Project Absinthe – Part II

Build Log:

Progress on Absinthe would have continued on Saturday had a little shipping concern not gotten in the way. Instead everything had to wait till Monday. This wasn’t a major deal as I had a parts installation for my personal computer to handle in the mean time, and I was able to figure out another little bit regarding cable management in the interim.

But come the Monday, when the power supply and the first GTX 660 card arrived, I got straight to work. My wife had a dentist appointment that day, meaning I would be home for the afternoon as I made sure to go in early for work knowing that was coming up. Here’s where I last left things off (actually this was before the fan controller installation, but close enough):

Power supply switch

Anyone who has ever changed out a power supply on a system, especially the kind with tentacles, knows how much of a pain it can be. You’re basically pulling apart everything. And given what we knew was going to be coming up, I wanted to make sure that this would be pretty much the last time I’d have to do that. Five of the fans in the system would be for radiators, so I needed to make sure I could still get them out of the way, but everything else could be “locked down”, so to speak.

But my foresight didn’t reach as far as I wanted.

As I have a CX750M in my personal computer, I had previously purchased the custom cable kit that Corsair sells. It comes with a lot of cables, and I knew I had more than enough to cover another power supply – one of the things that made me glad I went with a Corsair power supply.

But one thing that slipped my mind is that the RM power supplies are full modular, meaning the CPU and 24-pin ATX power cables are also modular. Now for the CPU, there was already a cable in the Corsair kit to handle that. But there was not one to cover the main ATX cable. Corsair sells that separately. Had I remembered that, I would’ve included it in an order from Performance-PCs that occurred around the same time. Instead I ended up overnighting it from them.

On her previous power supply, I had used extension cables for the CPU, ATX and PCI-E power cables since the tentacles on the GS800 aren’t all that attractive, nor were they long enough to adequately reach everything. But with the custom sleeved cable kit for the RM power supply, those cables were no longer necessary, allowing for much shorter cable runs and much less cable bulk to manage behind the mainboard. That is always a good thing.

Add in the attractiveness of the custom 24-pin ATX cable I had overnighted, and I didn’t need any of the extension cables I originally used, giving a significantly reduced cable bulk.

But when I first put the power supply in the case, I operated under the assumption I would still need them, so I didn’t get the cabling the way I wanted it. But I still managed to get case closed up and just left it to wait for the sleeved 24-pin ATX cable. That came on Wednesday, but as my wife had that night off, I didn’t work it until the next day in which I tore apart practically everything again. I had also made a trip to Microcenter to find a SATA to 2xMolex power adapter with the intent of using it to get rid of the Molex power cables I had also put into the build – I bought two actually so I could use one in my computer as well to get rid of the Molex power cable I have currently.

So with the redo, I was able to eliminate a lot of cable bulk – getting rid of all extension cables, plus eliminating the Molex peripheral cable. I also had a second GTX 660 on the way from NCIX, so I made sure to run two PCI-E cables, leaving one just dangling in mid-air beneath the first card. When the second card arrived on Friday, all I had to do was open the side panel and install the card and the SLI bridge without having to pull apart anything else.

Now there was one snag to my plans by going with the RM1000: the 240mm radiator won’t fit lying on the floor of the case, as the cables protrude too much from the power supply, and there’s no way around that. So instead, the 240mm radiator will be attached to the front with the front 140mm fans blowing into it. This means the hard drive cage had to be moved back to the floor of the case, immediately adjacent to the power supply.

But I was aware this might be a concern and had already planned for it, already had an alternate idea in mind.

Release the Kraken!

Both of us kind of got sick of the “jet engine” noise the AMD stock cooler provides, so I decided that I’d take the ThermalTake cooler off my graphics card and put it back on her processor. By the way, a Corsair SP120 did wonders for noise, though not much for cooling on that. I also took the opportunity to connect up the various temperature sensors as well to her fan controller. I only connected three, though, as the last temperature sensor spot would be for the coolant temperature sensor.

The locations of the sensors are the front of the case before the front fans (as in between the fans and the fan filter), near the rear intake fan, and between the ThermalTake radiator and top dust filter.

Changing out the fans

The 140mm fans that come with the 750D don’t really do all that well with the fan controller, so it seems. So I decided to look around, especially since all these Corsair fans currently in her system cause it to sound like a beehive when they’re all cranked up. I’m considering switching to NoiseBlocker fans, the PL-2 and PK-3, as I’ve heard a lot of good about them. But I’m also looking at the BitFenix Spectre Pro fans as well.

Here’s the comparison with her current fans according to their respective manufacturers (best ratings in bold):

PK-3 AF140 Spectre Pro 140mm
Operating voltage 3.5-13.8V 7-12V 5-12V
RPM 1700 1150 1200
Airflow 90 CFM 62.74 CFM 86.73
Static pressure 1.65 mm/H2O .84 mm/H2O 1.38 mm/H2O
Noise pressure 32.5 dB/A 24 dB/A 22.8 dB/A

So on operating voltage and RPM, the PK-3 wins out clearly. But on airflow, the Spectre Pro has only 3.6% less CFM than the PK-3. Static pressure is a bit less at 16% less static pressure. But the Spectre Pro beats everyone on noise pressure, only slightly better than the AF140 but significantly better over the PK-3.

Now let’s look at the 120mm fans (best ratings in bold):

PL-2 SP120 HP Spectre Pro 120mm
Operating voltage 3.5-13.8V 7-12V 5-12V
RPM 1400 2350 1200
Airflow 56.5 CFM 62.74 CFM 56.22
Static pressure 1.24 mm/H2O 3.1 mm/H2O 1.24 mm/H2O
Noise pressure 22.5 dB/A 35 dB/A 18.9 dB/A

On the 120mm front, the PL-2 wins on operating voltage, but the SP120 wins on everything else except noise, where the Spectre Pro again beats everything else. And again we see the BitFenix Spectre Pro comparing quite well to the NoiseBlocker fan, with a negligible difference in airflow and about the same static pressure while being noticeably quieter. Given that the radiators I’ll be using are low FPI radiators of moderate thickness, I don’t think having the SP120s will really improve cooling much compared to the PL-2 and the Spectre Pro, so static pressure isn’t going to be of huge importance on this one.

And on price, BitFenix wins hands down. On Performance-PCs, it’s half the price of the NoiseBlocker fans for very comparable performance, and on the 120mm front it’s still less expensive than the Corsair fans, providing a good price to performance ratio and being significantly quieter.

So I think that settles it: I’ll be going with the BitFenix Spectre Pro fans for the case and radiators.

Now I don’t think I’d dream of trying to use the BitFenix or NoiseBlocker fans on the radiator for either the Corsair H60 or the ThermalTake Water 2.0 Performer, as both radiators are very high FPI. But for the AlphaCool XT45s I will be using for the full loop, it shouldn’t be a problem.

Back up to speed

The EVGA RMA came through with a refurbished card, and I ordered a second GTX 660 from NCIX as well. The first card arrived on Monday, the second on Friday. The first card went in with the power supply change, and I ran Unigine Valley against it to stress it a little. After the second card came, I did the same. In Thursday’s adjustment to the cable management, I made sure to leave a PCI-E power cable ready for the card so I didn’t have to redo everything again to install the second card.

By the way, Unigine Valley benchmarked at 2337 on the GTX 660 pair, compared to 2140 for my single GTX 770. This was run on the ExtremeHD preset with her resolution being 1920×1080 and mine being 1680×1050 (I’m running on 7 year-old Acer 20″ monitors, but I’ll be changing them out later this year). If I follow the settings listed in a TechPowerUp thread, which calls for 4xAA, then the scores become 2779 (hers) and 2655 (mine).

Both GTX 660s were also getting around 80C when running the benchmark, and given the hot air that’s being belched out the back of the case, I think a desk fan could be in order to help keep that cleared away, especially since I have the rear 140mm fan on the case as an intake fan.

One thing to also note: during the course of the benchmarking and burning in the cards with Unigine Valley, the fan on the RM1000 barely ever came on according to the Corsair Link, despite it pulling at times over 26A across the 12V rail – i.e. over 300 W of power draw. On the GS800, the fan would’ve been running nearly continuously under that load, or would’ve been off and on a lot more frequently, which would’ve reduced the lifespan of that fan.

So that definitely shows that with my wife’s setup, you don’t need a super high-end power supply covering all of it – a 500W 80+ certified power supply should do the trick, with a 600W being a little safer bet. The benefit of the high-rated high-wattage power supply, though, is that the supply is so efficient at providing power with so little of it lost to heat, the fan is much less likely to come on even under the heaviest load you can put on your system. Combine that with quiet fans – such as the BitFenix Spectre Pros I’ll be buying later, or something similar – and you’re going to be rigged for a fairly silent running, even before a fan controller comes into the mix.

And given that the RM1000 is currently going for only $160 on Amazon (normally goes for close to $200 elsewhere), and that’s a lot of power efficiency for the price.

Here’s the parts list for how things stand: PcPartPicker. Enjoy a couple shots of the current state of things.

Computer build tip: Cable management

Walking through Wal-Mart one afternoon, I saw these and got a bright idea:

17017CLR_rgb_D

And that bright idea was to use these for cable management in a computer case rather than a butt-load of zip ties and whatever cable management holders happened to exist in my Corsair 750D. I was putting a SATA RAID card in my computer, so it was a good opportunity to redo the cable management and give it a try.

DSC_0861.jpg

Placing the fan power splitter up behind the 5 1/4″ drive bays and running all the cables to it certainly helped over where I originally had it. Then it was a matter of keeping all the cables organized. I think this worked out quite well, especially in the crevice along the front-panel where I could easily hide the cables for the front panel and keep them virtually completely out of the way of everything else.

DSC_0866.jpg DSC_0868.jpg

And being able to secure and route cables in this fashion allowed me to easily slide the back cover onto the case without any issues. All of the cables are kept pretty flat courtesy of these cable clips.

DSC_0865.jpg

Initially I bought only a couple 4-packs. When I went back to Wal-Mart to get more, I found a 16-pack on the racks for $8.88, compared to a 4-pack for shy of $4. This made my cable management life a hell of a lot easier, and I think I know of a good way to redo the cable management in my wife’s build – Project Absinthe – especially for the cables coming from the fan controller.

Now if you’re concerned about ruining the paint job on your case, don’t be. These come off pretty clean as I needed to remove one I didn’t actually need where I placed it and it didn’t take any paint with it. Still not sure if I’d trust it with a custom paint job, but if the paint is done right it shouldn’t have any concerns.

There are also larger clips available, and I just may look for those as it could make bundling the power supply cables a bit easier as well. For the most part, though, it’s all in how you run them. These clips just seem to make the job a lot easier.

Passive response to concerns

When someone breaks into your home, you typically take measures to ensure that future break-ins are prevented. In my case, there were two homicides within 6 months of each other within a half mile of where I live several years ago, along with the fact there are also nearly a dozen registered sex offenders also within that half-mile radius, so I take measures to protect myself – i.e. I carry a firearm concealed.

Yet it seems that the only responses to sexual harassment and sexual assault is pacifism. From SlutWalk Toronto’s Facebook page:

NB: We’d like to acknowledge and bring attention to the fact that there have been multiple accounts of participants being sexually assaulted at Pride this year (and in previous years). This is not acceptable by any stretch of the imagination. Clothes do not equal consent. Costumes do not equal consent. Participation in celebration and revelry does not equal consent.

There are some members of the community who will be bringing up these issues to Pride Toronto, as well as the Dyke and Trans March organizers. We fully support them in pushing to make Pride safer from sexual violence.

People are allegedly being sexually harassed and sexually assaulted at these events, and the only response is basically saying to people "Please don’t do that." How exactly do they think the event organizers are going to "make Pride safer"? Yet they have the nerve to call people like me a "rape apologist" and "victim blamer" because I have said that you need to be more proactive in your responses to these concerns while also taking more proactive measures to prevent them from becoming concerns.

Easiest pro-active measure: pepper spray. But bear in mind that pepper spray doesn’t work on everyone, so do try to have other contingency plans.

When overnight isn’t

Amazon really screwed up this time.

The morning of July 3, I ordered a new computer power supply. The order I placed had the option of Saturday delivery, to be delivered July 5. As I’m an Amazon Prime member, that "overnight" delivery comes at a much reduced rate, and I was charged only $6 to ship it. If the next day wasn’t July 4, it would’ve been an overnight delivery, but since the holiday got in the way, delivery was to be July 5.

And I say "was to be", because Amazon didn’t ship the power supply using anyone’s overnight service. Instead it got shipped FedEx Ground. FedEx Ground doesn’t have a Saturday delivery option.

Now the package was shipped from Coffeyville, KS, so someone probably thought it’d be an overnight delivery even if it was being shipped using the Ground service. Unfortunately there didn’t appear to be anything anyone at FedEx could do to get the package released, and the FedEx Ground hub is closed on Saturdays – I know exactly where that hub is as I’ve driven by it several times.

So instead I wrote in to Amazon demanding that they refund the shipping charges unless someone can get FedEx to release the package. I mean, I paid for overnight, they didn’t ship it overnight, so they at least owed me that, and they issued a refund on the shipping charges.

It’s a good thing that I’m not doing client builds – something I’ve actually considered doing – and that this order wasn’t for a client build. If it was, I’d probably have to visit my nearby Microcenter to see what other options are available as they don’t carry the power supply I ordered, and I ordered that power supply for a particular reason.

Project Absinthe

Build Log:

Project Absinthe started life as an upgrade from an AMD X2-3800 system running Windows XP. Here are the current specs on the system (PCPartPicker.com list)

  • CPU: AMD FX-8350, running at stock speed with stock cooler
  • Mainboard: ASUS Sabertooth 990FX R2.0
  • Graphics: Zotac GT 620 2GB
  • Memory: Corsair Vengeance Pro DDR3-1866
  • Power: Corsair GS800

I chose the name Absinthe for this project due to the green CCFLs lighting up the inside of the Corsair 750D case in which this system has been built. The coming upgrades include:

  • Graphics: 2xEVGA GTX 660 SC in SLI
  • Power: Corsair RM1000

I’m also considering adding a hardware SATA RAID card to the setup as well rather than relying on the “fake RAID” that is built into the mainboard. And yes there is a rather important difference between the two, especially when we’re talking about RAID 1 setups.

Once the system has been adequately broken in with the new graphics cards and power supply, it’ll be getting a water-cooling upgrade. Here are the planned parts (not including fittings):

  • Koolance CPU-380A
  • 2xEK FC-660 GTX
  • AlphaCool XT45 360mm
  • AlphaCool XT45 240mm
  • AlphaCool VPP655 pump with AlphaCool HF D5 clear top
  • Bitspower Z-Multi 150mL reservoir

It already has a Phobya TPC fan controller, and will be getting a Koolance temperature sensor plugged into one of the radiators – likely the bottom one unless the cable isn’t long enough to run to the fan controller, in which case it’ll be plugged into the top one. The other temperature sensors for the fan controller will be put at the top of the case above the top radiator, beneath the bottom fans, and in front of the front fans – currently they’re not installed. This’ll provide a good idea of the intake temperature from the front and bottom, coolant temperature and exhaust air temperature.

I’m not sure yet if I’ll be doing video build logs on the various parts. We’ll see.

Water cooling build in my wife’s computer – Part IX

Build Log: Absinthe:

For just $6, I was able to overnight a $160 power supply. Pretty sweet deal, courtesy of Amazon Prime. Anyway. I ordered the RM1000 power supply to go in my wife’s computer, and overnighted it courtesy of the great rate Amazon gave me. Plus as putting the new power supply into her machine would be a bit of work, having it on Saturday would give me plenty of opportunity to get the upgrade done while my wife’s at work.

Update from AlphaCool/Aquatuning

The night before ordering the power supply, I got an e-mail from Westfälische Provinzial Versicherung AG, the liability insurance company for AquaTuning:

Guten Tag, sehr geehrter Herr Ballard,

wir melden uns als Haftpflichtversicherer von der Aquatuning GmbH.

Eine Haftung unseres Kunden ist nicht ersichtlich.

Das Auslassgewinde hat einen Riss. Für die Inbetriebnahme des Kühlers wurden von Ihnen Bitspoweranschlüsse verwendet. Diese sind jedoch nicht normgerecht und hätten nicht verwendet werden dürfen.

Bitte haben Sie Verständnis, dass wir Ihr Ansprüche daher nicht anerkennen können.

Thankfully Google Translate and Bing Translator were able to make some sense of this.

Apparently what they said is the outlet thread on the CPU water block had a crack in it. They alleged that I was using Bitspower fittings on the CPU block, and called these fittings “non-standard” (I’ll get to that in a little bit). And because they believed I was using “non-standard” Bitspower fittings, they’re basically rejecting my claim for liability with regard to the CPU water block and the damage that resulted.

Now the thread having a crack on it would lead to what I felt caused the block to ultimately rupture: water leaking into the block’s lid, and eventually building up enough pressure that it leaked out. But I didn’t use Bitspower fittings on the CPU block in any way – pictures in earlier iterations of this build log will demonstrate such as none of the pictures show Bitspower fittings being used. I used only Swiftech and AlphaCool fittings on the CPU block, and specifically an AlphaCool 45-degree single-rotary 1/2″x3/4″ compression fitting on the outlet.

I sent this as the response to the insurance company:

You will have to pardon me as I do not speak German. Please provide the previous in English so I am sure of what you are attempting to say, and any future communications with me should also be in English.

An attempt to translate through Bing and Google’s translation services provides the implication that I was using Bitspower fittings on the water block sent in for evaluation. This statement is not correct. I was using an AlphaCool fitting on the outlet of the CPU block, as pictures and statements I have provided to [redacted] note. At no time did I attempt to use a Bitspower fitting of any kind on the CPU block.

As such, please re-evaluate the claim based on the previous. If you desire, I can forward to you the mentioned pictures.

I somehow doubt they’ll do that. But I can hope. This e-mail was sent shortly before 2am CDT. The next morning I decided that I should also contact AquaTuning’s support contact again:

I received an e-mail yesterday from Westfälische Provinzial Versicherung AG. From what I could get from the e-mail — it was in German, so I needed to use Google Translate to get some idea of what was being said — they are claiming that I used Bitspower fittings on the CPU block I sent in for evaluation, and that this resulted in the outlet thread becoming cracked. As you are aware from what I’ve sent you, I did not use Bitspower fittings on the CPU block.

Do you have any additional details from the investigation regarding the CPU block? I’m very curious as to how they concluded I used fittings I’ve never owned.

Now this isn’t entirely accurate. I did use Bitspower fittings in the water loop – 3x40mm extension fittings as other pictures show – but did not use any on any of the water blocks, and most certainly did not on the CPU water block, as the insurance company originally alleged. The support contact replied back saying he’d “chase this” for me.

“Non-standard” Bitspower fittings

So before getting much further, let’s get to the idea that Bitspower fittings are “not standard”. Virtually all water blocks in a computer water cooling loop are threaded for G1/4″. The technical name for this is 1/4″-19 BSPP. According to Wikipedia, the BSPP standard for G1/4″ states the thread calls for 19 threads per inch at a 1.337mm pitch, with the outer (“thread major”) diameter being up to 13.157mm, or approximately 0.52″, and the inner (“thread minor”) diameter being 11.445mm, or .45″. Any fitting or block advertised as being G1/4″ should fit this standard, to a reasonable degree of tolerance.

But if you take calipers to the fittings that you find on the shelf, you will likely not find a fitting with a “thread major” diameter of 13mm, let alone above it, but at minimum the fitting should have a “thread major” diameter of at least 12.7mm, or 1/2″. The Bitspower fittings I have are approaching 12.8mm, while the 45-degree single-rotary AlphaCool fitting that was on the water block has a “thread major” diameter of 12.9mm.

Now if AlphaCool is going to advertise their water blocks as being threaded for G1/4″, virtually anyone is going to presume that it will accept any G1/4″ fitting. So to say that Bitspower fittings should not be used is just hogwash, and I think they’re just trying to make stuff up in order to avoid the liability that comes with acknowledging the water block’s failure, and the documentation distributed with the block says nothing about the kind of fittings to be used with it.

Project Absinthe

Absinthe-glass

I am about ready to start building out a new water cooling loop in my wife’s computer. The video card from EVGA should be here on Monday, and the new power supply will be here on Saturday. I’ll be installing the new power supply right away as well, including installing cables knowing that not just one, but two new graphics cards will be going into it.

Once the graphics cards have been thoroughly exercised is when I’ll build out the loop. I think a week of my wife’s gaming plus a few long runs of Unigine Valley should do the trick.

And the green lighting my wife selected when she picked out her 750D has inspired me to name this next iteration Project Absinthe, and any future articles on the build will be under that title, starting with the new power supply, while any updates regarding AquaTuning and EVGA will probably still be under the current series.

Reply to Ragen Chastain

Back at the end of 2012, Ragen Chastain penned an article for iVillage called “Are You Guilty? 10 Ways We Body Shame Each Other Without Knowing“. I’ll just go through the list one by one and respond accordingly. But before I do, there’s on observation that needs to be made: Chastain is basically saying herein to take no interest in the welfare of others, especially if those “others” happen to be women. She’s not saying to choose your words carefully, but to just ignore the person you intend to speak to in order to preserve their feelings.

1. Saying Things Like, “She Would Be So Pretty If…”

Have you ever uttered anything along the lines of, “But she has such a gorgeous face” or “She would be more beautiful if she put on a few pounds”? You are limiting your idea of beauty to a cultural stereotype. Beauty is not conditional. If you can’t say anything nice, maybe it’s time to learn how.

Actually, beauty is conditional. What is considered beautiful is going to differ not only from group to group, but also person to person. There is no getting around this. And typically when a person says “she would be so pretty if…”, chances are the person is speaking from their own personal idea of what they find pretty or beautiful and not necessarily to any particular cultural standard or stereotype.

2. Judging Other People’s Clothes

While it’s fine for you to choose clothes any way you want, nobody else is required to adhere to your style. The person wearing that outfit is, in fact, pulling it off, even if you think she’s too flat chested, big chested, short, tall, fat or thin. And fat people don’t have to confine themselves to dark colors and vertical stripes, no matter who prefers it. And spandex? It’s a right, not a privilege.

This is only true to a point.

In all the various “body image” articles I’ve seen, they always tend to say that a person should be able to wear what they want and not be judged for it. Unfortunately that is not the world in which we live, nor will it ever be the world in which we live. Because you will be judged by how you present yourself.

I’m a working professional. In the building where I work, I can dress casually. And everyone around me, except the higher-level executives, also do the same. But we also dress in a way that is presentable. Because how you dress, how you keep your workspace, and the like can shed light on how you are professionally. Now you could be the best [insert job title here] in the world, but there is something called “dressing the part”. And if you don’t dress the part, it doesn’t matter if you’re the best in the world at your job title because no one will take you seriously.

A woman who shows up for work in a professional setting wearing tiny shorts, a tight shirt with a plunging v-neck revealing a lot of cleavage, and stilettos is not only not going to be taken seriously, she’s likely going to be sent home by her manager. And if a woman were to wear that kind of thing in public, any observer will make certain assumptions about who she is, regardless of whether they are true. Because you will at least be judged in thoughts by how you dress. And others will let those thoughts escape their lips – whether to friends and/or colleagues, or even to the person wearing the ensemble in question.

But the same is true if a guy were to show up for work in the same office with an overgrown beard, unkempt hair, wearing a “wife beater” and torn jeans or shorts, and sandals exposing advanced athlete’s foot and toe fungus, smelling like he hadn’t brushed his teeth in months or decided that whiskey is a good substitute for Listerine. Even if that guy happened to have graduated from college summa cum laude with a perfect GPA, is praised by all his colleagues for his expertise and experience, and might even command a star’s salary for it, what’d be the first thoughts popping into your mind seeing that guy? Yeah that’s what I thought.

Don’t go around telling others to not judge by clothing or appearance if you’re going to do the same.

3. Making It an ‘Us vs. Them’ Thing

The phrase “Real Women Have Curves” is highly problematic. Developed as a response to the tremendous body shaming that fat women face, it still amounts to doing the same thing in the opposite direction. The road to high self-esteem is probably not paved with hypocrisy. Equally problematic is the phrase “boyish figure” as if a lack of curves makes us somehow less womanly. The idea that there is only so much beauty, only so much self-esteem to go around is a lie. Real women come in all shapes and sizes, no curves required.

Any phrase that begins with “real women” should be dismissed outright, including the one that concludes this paragraph. For one, the definition of a woman/female is chromosomal – i.e. having no Y chromosome. And before anyone jumps down my throat about how I’m excluding male-to-female transgendered individuals with that statement, the thing that needs to be kept in mind is that they are not biologically female, and no amount of cosmetic surgery and hormones is going to make that a reality, just as no amount of cosmetic surgery and hormone treatments will make a female-to-male transgender a biological male.

But beyond this is the fact that making any statement that starts with the words “real women” brings to mind the “No True Scotsman” fallacy. Beyond the chromosomal definition of who is a real female, no person has the ability to define who a “real woman” is. The existence of transvestites and male-to-female transgendered individuals should make that painfully obvious.

And any woman who utters a phrase beginning with “real women”, likely also finishing the phrase in such a way that they are certain to be included in that definition, is just looking for a way to 1-up themselves over someone else, and should be dismissed accordingly.

4. Avoiding the Word “Fat”

Dancing around the word fat is an insinuation that it’s so horrible that it can’t even be said. The only thing worse than calling fat people “big boned” or “fluffy” is using euphemisms that suggest body size indicates the state of our health or whether we take care of ourselves. As part of a resolution to end body shaming, try nixing phrases like “she looks healthy,” or “she looks like she is taking care of herself,” and “she looks like she is starving” when what you actually mean is a woman is thin.

Body size can indicate the state of your overall health. It’s something any physician will readily tell you.

If you are rail thin, you are not getting the level of nutrition necessary to maintain a healthy weight, whether incidentally or intentionally – i.e. your nutritional intake is not keeping up with your metabolism. I know a woman who says she just doesn’t get hungry and needs to literally remind herself to eat, yet she’s been told that she must work hard to maintain the body she has. And illnesses and medications may make it difficult to eat and keep food down.

I knew a woman who was rail thin, mainly because her nutritional intake wasn’t really all that diverse, making it difficult for her to put on weight – yes calories aren’t the only thing that determine if you will put on weight or not. She was also somewhat sedentary and ended up being diagnosed with deep vein thrombosis while in her mid-twenties.

I was rail thin all through my teen years as well. Keeping weight on was actually difficult for me for several reasons. It’s interesting looking back because I could eat large meals without any problem and my peers would ask “where I kept all of it”. But then in my later high school years, I just stopped eating nearly as much and just wouldn’t get hungry. My weight in high school was too low – I graduated high school weighing about 155 lbs at 6’2″ with a 28″ waist size. Much of the reasons behind that were purely psychological as well as I was going through a lot at the time that I just didn’t discuss with anyone else, including my thoughts of and two attempts at suicide.

As such, the other side of the spectrum – being fat – means that at some point you were overtaking your metabolism on your nutritional intake, even if you no longer are, and have not worked off your prior excess.

One afternoon my wife and I were dining at the Ryan’s buffet in Clive, Iowa. At a nearby table were two obese individuals, a man and woman. Watching them eat, there is no way to draw any conclusion other than having a non-sufficient means of caring for themselves. I mean when you are scraping clean from your plate the last little bits of cheese sauce from the macaroni and cheese, I’m sorry but you have issues, even more so when you are literally holding the plate in the air near vertically so you can tip it to make sure you got every last little bit.

I wish I was making that up.

But that doesn’t mean their weight does not have a logical explanation for how it started. A friend of my wife’s gained a lot of weight after being on a steroid regimen, and weight gain is a known issue with individuals who are on corticosteroids. There are things that can be done to mitigate that issue, but as the reason for being on the steroids tends to get in the way of preventing the weight gain – i.e. movement being painful – sometimes it becomes unavoidable. And after the steroid regimen ends, often the patient has put on so much weight that getting it back off can be difficult, if not impossible, without higher-level interventions, whether due to the amount of weight gained or the weight putting stress on the body that movement is, again, painful.

And stress can also cause a person to overeat, known as “emotional eating” or “stress eating“.

Again, whatever the cause, in general losing weight means your nutritional intake is not keeping pace with your metabolism, while gaining weight means you are overtaking your metabolism. Even if you are maintaining your current weight, or close proximity thereto, being fat means at some point in your history, your intake overtook your metabolism. That is just the fact of the matter. You cannot put on weight without any kind of nutritional intake, plain and simple.

An ex-girlfriend of mine was a larger woman when I first met her. We got to taking walks – averaging about two miles round trip – about every night and she dropped weight very, very quickly. While other women were complaining about the “freshman fifteen”, she’d lost a bit more than that, so much so she had to go searching through her older clothes to find ones that fit. And again that was merely from walking a lot more than previous.

We are long past the point of weight being an indicator of wealth, where being fat was a good thing because it meant you were well off enough to be able to get fat. Today weight is an indicator of health, either past or present, while being a predictor of future health. Again, being fat today means that at some point in your history you started eating more than you were burning off, whatever the reasons may be, and you have been unable or unwilling to get that weight back off.

Further, pregnancy changes a woman’s body quite a bit as well. Some women can bounce quickly to their pre-pregnancy weight, while others cannot. My sister-in-law was the former, and from pictures I’ve seen, so was my mother. And if a woman who does bounce back quickly from their pregnancy decides to show it off, don’t go around calling it an “act of war” or something else like that. And if you want to increase your chances of getting back to your pre-pregnancy weight after giving birth, talk to your doctor about an exercise routine you can keep while you are pregnant, and what adjustments can be made to it after birth.

But then if you’re not talking to your doctor while you are pregnant, why the hell not? And if you are but you are not discussing a fitness routine, again, why the hell not?

5. Making Up Body Parts

We could all lead very full lives if we never heard the words cankles, muffin top, apple shaped, pear shaped or apple butt ever again. We are not food.

So basically we should stop inventing ways of simplifying a description of something? Do I have that right?

6. Congratulating People for Losing Weight

You don’t know a person’s circumstances. Maybe she lost weight because of an illness. You also don’t know if she’ll gain the weight back (about 95 percent of people do), in which case earlier praise might feel like criticism. If someone points out that a person has lost weight, consider adding something like, “You’ve always been beautiful. I’m happy if you are happy.” But if a person doesn’t mention her weight loss, then you shouldn’t mention it either. Think of something else you can compliment.

You may not know a person’s circumstances, sure. But then you shouldn’t be congratulating someone you don’t know. This means that if you’re going to congratulate someone on losing weight, you should already know the circumstances behind the weight loss. If it was due to an illness, you should already know that before you say a word of comment. She may not see it as a good thing, or then depending on the illness, she may also see it as a wake-up call, a signal to change her lifestyle. But this is something you cannot know without, you know, having a conversation with her.

But something tells me, Ms Chastain, that you are discouraging even having that conversation.

In general, however, a person who lost weight worked to lose it, rather than it coming off because of some illness. As such, saying you should not congratulate someone for losing weight is about the same as saying you shouldn’t congratulate someone for accomplishing something that required a lot of hard work and commitment. Because that is what weight loss typically requires, a lot of hard work and commitment, including committing to a change of lifestyle.

As such, you shouldn’t congratulate someone for losing the weight, but for committing themselves to a healthier lifestyle. Losing weight requires a lot of change in your life, and there is no easy answer to whatever the issue might be. Commending the person for the life change, as opposed to the result of that change, can give that person a little bit of an emotional boost for keeping it up, helping them overcome any lingering doubts about their choices and changes.

But then if you’re going to congratulate someone on losing weight, you already know two things: they were previously heavier, and they thinned down in some fashion. A conversation with that person should open with a verbal observation of the weight loss, possibly a compliment on how they look, while allowing them to fill in the details if they so desire.

7. Using Pretend Compliments

“You’re really brave to wear that.” By the way, wearing a sleeveless top or bikini does not take bravery. “You’re not fat, you’re beautiful.” These things are not mutually exclusive — a person can be fat and beautiful. “You can afford to eat that, you’re thin.” You don’t know if someone has an eating disorder or something else; there is no need to comment on someone’s body or food intake. “You’re not that fat” or “You’re not fat, you workout,” need to be struck from your vocabulary. Suggesting that looking fat is a bad thing is also insulting, so also out the door are, “Does this make me look fat?” and “I look so fat!” when you are a size 2.

As I’ve already discussed above, your weight can be an indicator of your health. As such, being fat can be a bad thing. That’s just the reality of it, and there’s plenty of science to back that up. And reality can certainly be insulting at times. Avoiding talking about the consequences of your past actions is not the same as avoiding the consequences of your past actions, but we all seem to think that to be the case.

Let me also be clear that this is not the same as the consequences of your past actions being your fault where the consequences were unavoidable. For example, going on the previous example of steroids, you can either live with the pain and inflammation, thus leading a somewhat miserable life as a result, or you can go on the steroids and risk the weight gain instead. I think most people would choose the latter, even though both options pretty much lead to weight gain, either from being sedentary due to the pain, or as an effect of the steroids.

But this also means that looking fat or being perceived as fat can lead to a perception of being unhealthy. And a perception of being less than healthy can lead to a perception of being less than attractive.

Now saying to a person that they’re “brave” to wear something is not a compliment, not even a “pretend” compliment. Think of how it is typically uttered. It is an indicator of the kind of reactions others may have upon seeing the person in the outfit in question. It can also be an indicator that the outfit in question could have been unexpected or uncharacteristic, or something unique that might be attention-getting. Plus I’m sure we’d all call the Marines who served in the Middle Eastern desert “brave” for all the stuff they had to wear, whereas anyone who wore all of that in the middle of the desert in the middle of summer without a need for doing so would likely be considered foolish.

And yes, a person can be both fat and beautiful. A ready example for me is my wife – and no I’m not just saying that simply because she might read this. Queen Latifah also comes to mind.

Commenting on a person’s body or food intake when you don’t know the person I’d agree is quite rude. But if you do know the person, then the intent on commenting on their body and/or food intake is important. For example, if your best friend were to compliment on your body and/or food intake, would you think they were doing so for malicious reasons, or out of a genuine concern for your health and well-being?

8. Thinking of Women as Baby-Making Machines

One of my readers mentioned that her gynecologist called her “good breeding stock.” Also awful: “baby making hips.” Worst of all is when people ask fat people when they are due. As has famously been said, unless you can see the baby crowning, do not assume that someone is pregnant.

It’s kind of difficult to not think of women as “baby-making machines” because, hate to say this, they are. In case you happened to have missed that part of your sex ed classes, women are only the ones who can and do get pregnant. And their bodies must support the nurture of the growing fetus while pregnant until the point where they give birth – abortion notwithstanding. And this reality is reflected in the fact that one of the questions asked soon after a woman gets married is when they are going to “start a family”.

This means that being able to conceive and carry a child to term is part of what it means to be a woman, and that has been the case for millennia, and will remain the case probably till we are extinct.

A woman who is unable to conceive or who has difficulty conceiving may have feelings of inadequacy or inferiority. Thus saying the words “good breeding stock” or that a woman has “baby making hips” may seem to be in poor taste, but, again, the intent behind the words is also important – just as saying the word “nigger” is not racist without any context. And given that women can have feelings of inadequacy if they are unable to conceive, and may be treated as inadequate or substandard even by other women, the intent behind those words is typically reassurance, since, again, a lot of women place a lot of their own self-worth on their ability to conceive.

And no amount of saying the equivalent of “you shouldn’t place your self worth in your ability to conceive” will change that since, again, they are typically being judged by other women. How so? Just see how mothers respond upon hearing a woman who says she doesn’t want to have kids, the comments, judging and attempted 1-ups-manship that results.

Indeed, the law allows marriages to be annulled if one partner to the marriage knew they were infertile or not “good breeding stock” and did not disclose it. For example if a guy knew he was shooting blanks, or had obtained a vasectomy before getting married, and failed to disclose that to his new wife before they got married, then the wife can file for an annulment. Same for the husband if the wife knew or should have known that she was infertile but did not disclose it – for example if the woman has Turner’s syndrome but never mentions it and the husband later discovers it.

And assuming that someone is pregnant is quite different from voicing that assumption. I can assume all I want, as making that assumption is mere thoughts and little more. So I’ll assume all I want whether a woman might be pregnant, but I’m not going to voice that assumption as I prefer not having red marks on my face I’d have to later explain to, of all people, my wife.

9. Sticking Your Nose in Other People’s Exercise Routines

A subtle form of body shaming occurs when people make assumptions or suggestions about someone’s exercise habits based on their size. Don’t ask a fat person, “Have you tried walking?” Don’t tell a thin person, “You must spend all day in the gym.” I have had people at the gym congratulate me for starting a workout program when, in fact, I started working out at age 12 and never stopped. I had a thin friend who started a weight-lifting program and someone said to her, “Be careful, you don’t want to bulk up.” How about not completely over-stepping your boundaries and being rude and inappropriate?

Again, given that being fat means you at some point in your life started or continued eating more than you were burning off, and that being fat seems to imply not having the willingness or ability to work it off, asking whether they have “tried walking” is a way of giving a person a simple start at solving a complex problem. See my anecdote above about my ex-girlfriend and the walking we did on a near nightly basis. It can be a simple change that can lead to a healthier lifestyle, leading to a healthier life.

Saying that a thin person must “spend all day at the gym” is characteristic of the hard work that typically comes with trying to maintain a lower weight, especially since many weight loss “success stories” turn into failures after the celebration is done – hence why I said earlier that one should congratulate someone who lost weight on their change in lifestyle, instead of the results thereof.

Saying to a woman that she “doesn’t want to bulk up” is an implication that she could actually be seen as less attractive or even intimidating to men if she puts on some muscle, thus affecting future relationship prospects, and also future prospects at becoming a mother, especially since if your exercise routine is too intense, it could also lead to amenorrhea.

10. Playing Dietitian

If you have no idea how much a person eats or exercises, you shouldn’t tell her to eat less and move more or suggest she put more meat on her bones. (Even if you do know what she eats, don’t do it). How do you know she’s looking for nutritional advice from you or the newest weight-loss tip you saw on Dr. Oz?

Personally I don’t think anyone should be taking weight loss tips from Dr Oz, but that’s beside the point. Anyway.

I firmly believe that a person should not be giving nutritional advice without being a nutrition specialist or a registered dietitian – and yes there is a big difference between the two, and if you don’t know that difference, learn it. But suggesting that a person “eat less and move more” is not “playing dietitian”. Instead it is passing along the common idea that losing weight means moving around more, thus burning more calories, while also limiting your caloric intake. The specifics therein, however, would determine whether a person is trying to act like they’re a nutrition specialist or dietitian.

For example, my mother in law is a nutrition specialist, but not a registered dietitian. But watching her design meals, I can definitely tell she knows what she’s doing. As such, if she saw me preparing a meal and knew of a way to make it better, nutritionally or even just on flavor, I’d likely welcome the advice. Whether I used it right then and there would be a whole other matter, but I’d probably keep the advice in mind for the future.

And if I caught wind that a friend of mine had switched to, say, the paleo diet or something else like that, I’d be doing what I could to get that person off that diet and back into a more sound and sane nutritional path.

* * * * *

I said at the start of this that Ms Chastain appears to be taking on the perspective of just ignoring other people. If a person is fat, you should just leave them alone, even if you know them. Same if a person is thin. Or wearing rather questionable attire that is drawing a lot of attention from others. That’s at least the gist I get from this.

And if we were talking about two people who were perfect strangers, I’d be inclined to agree. But even then she is basically saying that even if you know the person, you shouldn’t have any kind of concern for their welfare. And, I’m sorry, but no. If I feel a friend of mine, or a colleague that I know well, is making questionable choices, it would be irresponsible for me to not do or say something.

I mean, what would you say to a woman who is smoking while pregnant and around kids she already has? Would you say nothing? Somehow I doubt that. What if she were drinking while pregnant? Doing drugs? Again, would you genuinely sit around and do or say nothing? Same if a woman is drinking like a fish and getting herself into questionable circumstances, would you say or do nothing? Oh wait, that’s blaming the victim, or is it only such when men point out that she’s drinking like a fish and getting into questionable circumstances?

The thing is that if you actually care about someone, you’ll try to help them. Interventions come from this. And sometimes some tough love through an intervention is necessary, but if I’m interpreting Ms Chastain’s words correctly, she’d even be against anything like that.

Water cooling build in my wife’s computer – Part VIII

Build Log:

The day after posting the last part, the AlphaCool CPU water block was confirmed delivered in Germany. I’m definitely curious as to what they’d find.

And the next day, I got the GTX 660 in the mail back to EVGA. I’m thinking the reason they accepted the RMA request was simply because of what I wrote in the request: the fact I’d be knowingly sending them a damaged card that got damaged from a faulty component in a custom water loop. The fact I explained that up front I think allowed them to be willing to work with me. After the faulty card was confirmed received by their RMA department, they shipped out something the following Monday (they received it on a Friday).

And given a new serial number got registered to my EVGA profile, it was a new card they shipped out. Hopefully the repair bill won’t be too high. Unfortunately it won’t be here till July 7th.

Controlling the fans

In the mean time, the fan controller and temperature sensor both arrived. I also bought a couple splitter cables to go with it: a 3-fan splitter cable for the top radiator, and a 2-fan splitter for the lower radiator. Well I should say that’s what I ordered, but two 3-fan splitters is what arrived. I notified Performance-PCs pretty much right away to get the situation taken care of. I had another 2-fan splitter already, but the one I ordered was sleeved. And after a small e-mail conversation, they put the right part in the mail and I’ll be mailing the incorrect item back to them.

This isn’t the first time I’ve had to work with their customer service. In one instance earlier this year, the first order I ever made with Performance-PCs actually included a length of acrylic tubing that I never ordered, and I wrote in about it. Back in May I had to file an RMA with them over a custom cable I ordered that came apart on the first attempt to test it.

But the fan controller along with the temperature probe and fan splitter cables were really the last parts I needed before considering how I was going to build out the loop. The fan controller was also going to be installed in the system first, ahead of everything else. This was not only to play around with it, but it also gave me a chance to get the Bitspower X-Station I out of her system. As I said previously, I intended to repurpose it for powering a Raspberry Pi among other things I plan to use with it.

Plus it gave me an opportunity to redo some of the cable management in her case. Well mostly…

New power supply

And I say “mostly” because her power supply isn’t modular. And I might change that before putting in a new loop just to make things significantly easier, but it’ll happen eventually. It’ll just be easier to do it at the same time as her loop. Now my power supply is modular, mostly. I use a Corsair CX750M with the custom sleeved cable kit. So I definitely can speak to the convenience of a modular power supply compared to one that isn’t.

Currently she has a Corsair GS800, which is 160mm long from the back of the case inward. I was originally considering replacing it with an EVGA 1000G2, a gold-certified 1000W power supply. But that’s not going to work.

I plan to have the 240mm radiator laying on top of 25mm wide fans on the bottom of the case. The technical drawing of the radiator shows it to be about 280mm long total length, with about 35mm between the screw hole and the longest edge of the radiator. The EVGA 1000G2 is 200mm long, meaning how I plan to run the radiator should I go with that power supply will be a tight fit given the position of the fan mount points. The clearance provided by the fans will give room to reach the bottom connectors on the power supply, but the mainboard connectors will likely be blocked.

So instead I’ll go with the Corsair RM1000 power supply, another 1000W gold-rated power supply that is 180mm long, only 20mm longer than the current power supply, and being 20mm shorter than the EVGA power supply, the fit will be a little looser around the radiator. The power supply is also full modular, like the EVGA power supply. But that’ll be an upgrade that’d happen later down the road, such as the next time I would need to drain the loop for maintenance, or when I put the graphics cards into the loop. I considered the AX860, but given this build will have two graphics cards in the end, the 1000W supply would provide good headroom for everything that’ll be in this.

Ethylene glycol

More and more of what I’m reading regarding ethylene glycol with regard to water cooling loops is making me more and more regret going with the XT1 coolant from Mayhem’s. One item I’m considering for a loop in my computer is rigid tubing, specifically PETG since it is supposed to be stronger than acrylic, nearly as strong as polycarbonate, but with pricing more around acrylic than polycarbonate. One of the main suppliers of PETG tubing for water cooling loops is PrimoChill. In looking at their website for the tubing, I discovered this under the “Warnings/Cautions” tab (emphasis mine):

With the use of different components, materials, fluids, and flow rates, results may vary with the appearance of your tubing. Rigid PETG Tube is designed to work with a large variety of cooling components, however the use of alcohols, Ethylene Glycol and as well as any other harmful chemicals is strictly prohibited and will void your warranty. PrimoChill is not responsible for any damage caused by or when using this product. Please use at your own risk.

And on the pages for their fluids (Ice and Pure), they further state that they do not use ethylene glycol in their coolants. But I couldn’t find anything to indicate that ethylene glycol would’ve reacted badly with the CPU water block or the tubing, and AlphaCool’s own CKC “Cape Kelvin Catcher” coolant contains ethylene glycol!

This is just getting more frustrating. Hopefully AlphaCool will be able to find something out. In the mean time, I’m using the Koolance block for the loop, and I’ll probably go the same route for my computer as well.

Now ethylene glycol should not be used with PETG tubing. PETG is polyethylene terephthalate glycol-modified, and ethylene glycol is already known to not react well with it, hence PrimoChill’s warning. Propylene glycol doesn’t have any known concerns with PETG. But both ethylene glycol and propylene glycol should not be used with polycarbonate, in case you were considering buying polycarbonate tubing and building your loop with that.

Ethylene glycol also does not have any known concerns with polyvinyl chloride, or PVC, which is the material for the tubing I used in the loop. And then there’s PMMA, or polymethyl methacrylate, also known as acrylic or Plexiglas. According to my research, ethylene glycol shouldn’t have any reaction with that either. So again, hopefully AlphaCool will figure something out.

Speaking of, they got back to me on the 30th of June confirming they received the block and started their investigation. They wanted to know the fittings I used along with whether I had pictures of it installed. I sent them two pictures from an earlier article in this build log along with the compression fittings I had in the loop. Hopefully the investigation won’t take too long.

Storing coffee

Depending on where you read, you could find all kinds of methods for storing coffee. There are all kinds of specialty air canisters and the like, but often it is the simple solutions that work best.

For the longest while I had been buying coffee from The Roasterie here in Kansas City. Typically I’d get their smallest offerings, a 12oz bag of whole beans. This would typically take me about 2 weeks to get through, so buying coffee to correspond with my pay cycle worked well. The Roasterie also has a coffee subscription program called "Autopilot" that sounded intriguing, which gives you a 10% discount for signing up. But the program only calls for the coffee to be sent weekly, monthly or bi-monthly, meaning I’d either end up with wasted coffee or not enough of it if I stuck with the 12oz bags.

So I looked into the 2lb bags, the next highest increment.

I have an Airscape, which can hold about a pound of coffee and is the perfect size for the 12oz bags. Obviously this isn’t going to be enough, and I didn’t want to buy another. Instead I looked into other options, namely vacuum sealing.

My research pointed me to the Waring Pro Pistol Vac (buy now on Amazon). A little more expensive than some other options, but after reading mixed reviews on other methods and offerings to vacuum store coffee, I figured it’d be the best shot. I didn’t want a counter-top vacuum sealer, nor did I need one. And FoodSaver’s handheld bags shouldn’t be used for coffee grounds or beans, as the oils from the coffee can get into the valve and prevent a good seal from being made. That’s due to the kind of valve they use on those bags. Instead the only mention for coffee on FoodSaver’s web site is with regard to using a canister.

Except my research led me to believe that negative-pressure storage shouldn’t be used either on fresh-roasted beans. I don’t buy the beans off the shelf at the grocery store – a lot of which has been nitrogen treated so they end up with a longer shelf life, but a muted flavor. The best way to tell if the beans are nitrogen treated is to look on the bag and see if there’s a "sell by" date instead of a "roasted on" date. Anyway, another option is what is called positive-pressure storage, basically storing the beans under CO2 pressure to also prevent degassing. Except that would mean having to buy CO2 as well and something to try to pressurize a container with it (somehow I doubt the SodaStream would do that).

But that is what vacuum storage is about: preventing degassing and trying to keep that freshly roasted flavor as long as possible by removing all of the air that could cause the beans to continue oxidizing. And that is what led me to vacuum sealing.

And the Waring Pro Pistol Vac seemed to be the best option available from all that I’ve researched.

I’ve been using it since February, and so far I haven’t had any issues. The 2lb bag of beans I get from The Roasterie lasts me now about 6 weeks, so still not the right increment for joining the Autopilot program, but oh well. The 2lb bags are a better value over the 12oz bags anyway – $26.94 for the 2lbs (about 84 cents/oz) vs $12.89 for the 12oz ($1.07/oz) – so being able to buy the 2lb bags and vacuum seal what I’m not immediately using, while keeping the Airscape for what I am immediately using, has so far allowed me to save both time and money – I’m not having to pick up coffee nearly as often, and I’m not spending as much for it.

But there is a caveat. If you vacuum seal the beans not long after roasting, you may need to check them every couple days to ensure the bag hasn’t puffed up and vacuum it again if it has. That doesn’t happen from air getting into the bag, but from continued degassing of the beans. It’s why beans tend to be sold in bags with one-way valves: allow the CO2 to escape but prevent more air from coming in.

Cooling off a Raspberry Pi, revisited

Previous: “Cooling off a Pi so it won’t crash

I have to admit that before starting this little experiment I was a little nervous about how it would all work. I wasn’t sure if I’d succeed or if I’d end up frying my Raspberry Pi and possibly a power splitter board, and perhaps a power supply in the process.

DSC_0841.jpg

Here’s the setup: I had the Raspberry Pi powered off one of the 5v connectors on a Bitspower X-Station I. There are 3 of them, so in theory this setup should be able to power three Raspberry Pis while also providing for fan cooling on all of them as well. The fan in the picture is a ThermalTake fan that came stock with a ThermalTake Water 2.0 Performer all-in-one CPU water cooler. The fan was plugged into a 12v connector. I later tried a Corsair SP120 High Performance fan as well.

And all of this was powered by a 500W Rosewill Stallion power supply. Note: I needed to use a 4-pin Molex extension cable on the power splitter board as the power supply’s connector had difficulty getting a solid connection that would allow the 12V connectors to be powered.

DSC_0849.jpg

The cable connecting the X-Station to the Pi was built from a female-to-female 3-pin fan extension cable distributed with an NZXT Grid, but I had to modify the end going to the Pi. The pinouts for these connectors are, looking down at it from the non-keyed side, pin 1 is ground, pin 2 is 12V, and pin 3 is the RPM sensor signal. To power the Pi on the GPIO, you need to put 5V into Pin 2 and ground into any of the ground pins, the nearest being pin 6. And the keyed connector won’t fit as-is, but you can cut the key slots off the connector and then you can slide it onto the pin array.

So basically you need to change it so Pin 1 on the connector is 12V and pin 3 is the ground with nothing in the middle, as the above picture shows. And to make it fit, just shave or clip off the keyed rails on the connector. If I had the knowledge along with the materials, I might have tried to build something directly rather than adapt something. Perhaps that’s a future project, or I’d solder the wires directly to the board and get rid of the GPIO pins completely.

DSC_0848.jpg

And it’s keeping the thing nice and cool, with the copper heatsinks helping as well. That number you see below means the core temperature is registering at 27.171°C (80.9°F). As I mentioned in a previous article, the Pi will crash if the temperature gets into the upper 40s Celsius. And using a Corsair SP120 (a fan typically used on water-cooling radiators for PCs) didn’t fair much better, perhaps a half a degree Celsius at best.

openelec.png

So now that I’ve got a viable way of powering and cooling the Raspberry Pi, or at least another proof of concept, I’m going to see what else I can do with this. I know that the power board can also be used to power a hard drive, or I can use the power supply for that as well. But as I’m considering an enclosure for all of this, with a fan to keep it all nice and cool, I’ll want it all powered off the Bitspower X-Station, and then I can use a SATA data to USB converter to get it into the Pi.

The reason to go that route is I actually want to set up a small NAS with the Pi as the server. And if I can power everything off the Bitspower board, using a PC power supply, most likely, or something that I can adapt to provide power to it, I should be able to have pretty much an enclosed unit. I’ll see what I can come up with on that. The idea I have in mind for an NAS enclosure is a chimney-type setup with airflow coming from the bottom and exhausting out the top with the Pi, X-Station and hard drive held vertically. And using a hard drive off it would actually give me a sense that I’m doing something with the board as opposed to using a $20 power splitter for just two items.

These temperatures are not significantly better over the 40mm fan I originally used, meaning using an 80mm fan would probably suffice just as well, though a 120mm fan would provide adequate airflow to cool the Pi and a hard drive when blowing across both. Now for just a small media center device, an 80mm or 40mm fan would work just as well.
