My rack setup, $14 plastic shelving w/modular individual PVC framework. I can deploy these 1 shelf at a time, or stack them to any height. Just add power and ethernet cable.:


"Air intake" side, 120mm silent fans push air between cards:


Best GPU cooler ever, the Prolimatech MK-26 setup (from the rear) dual 140mm silent fans cool the GPU, while this large heat sink on the back helps dissipate heat as well:


That's my general rack deployment setup. Low quality image but it gives you an idea. The 2nd unit from the top are the new R9 280x's I just threw up there to warm up. Going to take them out in a few to replace the TwinFrozr IV with the Prolimatech MK-26.

24kilo, I take bamt 1.1 and then upgrade it and add some tweaks to it (to satisfy my tastes). If I'm doing it from scratch, I burn the image onto a USB stick (8gb adata professional, it's like $9), change the user password, change the admin password, and then github the latest cgminer. I then pick a particular version from the repository (I'm peculiar), which I know will work for sure. Install all required dependencies then build cgminer. Then I modify some of bamt's scripts to suit my tastes, pointing it to the new cgminer (keeping the old one as a backup), adding some custom commands to make remote monitoring easier basically.

While I like bamt's built in web monitor, I don't use it, as I just SSH in and take a look at cgminer.

For anyone curious, all of my GPU rigs use the Prolimatech. The rack you see is absolutely silent, keeping most cards in the 50*C range, sometimes 60's depending on how bad off the cores are, and also depends on the ambient temperature and some other factors. The GPU's are spaced very far apart, I use a double riser for the end card to spread them out; it's hard to see. The cooler itself sticks about 4" past the GPU, it's a 3 slot cooler.

I have a write-up somewhere on my particular bamt modifications if you're interested. I've got this rack currently pointed your way Fuse, with all it's 8mh fury lol.

Vesper,

Thanks for sharing... what a great set-up!!!

Do you like the Prolimatech MK-26(can't find them for sale in Australia) better than liquid cooling? My 16-year-old son is determined to water-cool everything!!!

Curious what temps you run on the 280X's as mine run about 77C-80C... and pretty much everything you said about BAMT was 'greek' to me... I never used a batch file until cgminer a few weeks ago!!

I have no doubt!

Vesper,
Thanks for sharing... what a great set-up!!!

Thanks, I'm fond of them Smiley

Do you like the Prolimatech MK-26 better than liquid cooling? My 16-year-old son is determined to water-cool everything!!!

Long version:

I haven't liquid cooled a mining rig, I have done it for a regular sysem. For a mining rig there's a few "sensible" options for liquid cooling, specifically a simple closed-loop system like the Arctic Accelero Hybrid. There's some DIY setups as well which use the same design for about half the price. Here's how I came about the Prolimatech (In Silver and In Black:

My situation wasn't the normal "gamer looking to cool his GPU", I'm looking to cool racks. The stock TwinFrozr III setups started to die slowly, and I was having MSI replace them for free ($10 shipping on my part). But that isn't ideal. And cooling means longevity, and that's what I need in a rig. SO I needed a new cooler. And I needed many of them, at least 12-16 to try out, with the availability to purchase more and more.

The goal was, in this order: Reliability, Cooling, Silence, Ease of installation. The solution also had to support the modular setup of my racks, so it had to be physically tied to the PVC framework in case I moved them. I researched about 100 places with reviews on many coolers. I ran across a forum where a person has dedicated their bank account to reviewing 7950/7970 cards & setups of all brands, along with all possible cooling options. This was cool, and is what led me to my decision.

Basically it boiled down to a closed-loop liquid cooling option, like I linked above, or the Prolimatech MK-26 (The DeepCool Dracula needs mentioning, as it's essentially nearly the same, but is 2x as much and you can't find them anywhere). In every review I could find, the Prolimatech and Hybrid were pretty much dead even for noise level and ability to dissipate heat. In 2 independent reviews, however, the Prolimatech came out quieter than the liquid cooling option as measured by several devices. I started leaning toward it at that point.

Upon further analysis, the decision was clear: Prolimatech. What nailed it for me: It's a universal cooler, it will work for 20+ GPUs, and most future GPU's as well. It comes with a bunch of fittings. So it will be useful beyond the life of the GPU rig. It was $25-75 cheaper than the liquid cooling solution (even the DIY systems), and easier to install.

More important was reliability. If a pump fails on the liquid cooler, the GPU is dead. If a fan fails on the Prolimatech, the cooler is actually capable of dissipating the heat without the fan (up to 300watts without fans -- I checked this myself running them without fans and they stayed on par with the stock cooler).

TLDR; Prolimatech was the clear winner for noise level, cooling, availability, price, ease of installation and ease of maintenance (zero maintenance). It will also fit many other cards. So far I've bought 3 crates of them LOL. Amazon, FrozenCPU, Newegg and various outlets on ebay must wonder what I'm doing with them. When I say it's silent, I'm not joking. You have to put your ear onto the fans to hear them. It gets the wife approval as well.

Curious what temps you run on the 280X's as mine run about 77C-80C... and pretty much everything you said about BAMT was 'greek' to me... I never used a batch file until cgminer a few weeks ago!!

The MSI R9 280x's I just got are currently running at 59*C @ 740kh, one of them is at 68*C because it isn't spread apart from the GPU next to it. The fans are running around 2700rpm which I believe is 85% (in comparison, the Prolimatech fans run at a static 1000rpm). This is with a low gentle breeze of 40*F coming from my cold air fan about 4' away. I'm waiting on my next shipment of risers so I can spread it apart--it would be around 59*C as well if it was spread apart.

The TwinFrozr IV cooling system these come with is very impressive, the cooling is close to the Prolimatech (though still about 5*C shy of the Prolimatech), but it's nowhere near as quiet. It is MUCH quieter than the TwinFrozr III setup though (they sound like jets). This just sounds like a low whir. So I would definitely say the TF4 is probably the superior "stock" GPU cooler out there right now.

But, I like "silent" and the fact the Prolima's can take hardcore abuse and not even require a fan, thus tomorrow I'll be putting some Prolimatech's on them.

Forgot to mention, these are the fans I'm using on the coolers: http://www.amazon.com/Prolimatech-Blue-Vortex-14-Fan/dp/B0045FE3V8/ref=sr_1_1?ie=UTF8&qid=1387256228&sr=8-1&keywords=vortex+14+fan

You can get them from Newegg through ebay for $1 cheaper, but they limit you to 5 per order.

All my cards are running in the high 70C's... I do my best to keep them below 80C even if it is 79C... also it is summer time here with outside temps approaching 35C or more... we had a cool day not long ago and all the cards were running in the high-60C's.

What is my life expectancy on my cards at these temps?

What is my life expectancy on my cards at these temps?

That's not bad since it's summer down there. I wish I could tell you a good life expectancy, I'm not sure though. I can tell you my experience so far. My 7950's have been in use since late September/early October, with the temps in the mid to high 70's for a long time, a few hit the upper 80's because it was hot here. I have some other of the same model which I got second hand from a guy who'd had them in use for about 3 months, in the low 70's.

So far, only 1 card has failed, and it was one of the ones he gave me. That's about 6 months of use with mixed temps in the 70's. The rest are still chugging away just fine. So if I can expect 6 that's awesome, I'm hoping for 9, 12 or even more.

My estimation is, with an aftermarket cooler, you'll increase longevity. The MSI 7950's have sucky VRM cooling. 2 SCR's (or similar) aren't cooled at all, and 1 of the RAM chips is also not cooled. The Prolimatech fixed all of that, and I'm sure any aftermarket cooler (especially an Arctic product) would do the same.

The MSI R9 280X models have better VRM cooling, but it appears 2 RAM chips are uncooled. The RAM chip cooling may not be as important, but I still want to try to squeeze every hash out of these.

I have run two variations of the 280X so far...

Gigabyte GV-R928XOC-3GD and the Sapphire Dual-X R9-280X

The Gigabytes run cooler, but only run about 720Kh/s while the Dual-X run hotter but cruise at a solid 750Kh/s... I can try to post some screen shoots if you want.

I under-volt the Dual-X to 1.180 and the Gigabyte to 1.160... the Dual-X run at 1080/1500 and the Gigabyte at 1036/1500... for some reason the hashrate just plummets on the Gigabytes above 1038 on the GPU.

I've got some of the Gigabyte's on order to try out. If they ever get released from backorder. I believe what you say though. I've heard good things about both.

These cards are so hard to get ahold of right now.

I have first dibs on any 280X's at my local and I am getting about 1 or 2 cards per week... I prefer the Dual-X because they are $25 cheaper and since I am looking at aftermarket coolers, that goes a long way to cover the cost of a cooler.

I can expand slowly as I am only using 'free money', that is funds that I can find out of the weekly budget as I do not want to borrow money for this project. I am buying gear instead of coins as I want to be able to liquidate equipment even if it is at a 50% loss if all this goes pear-shaped.

I am really hoping TAG moves back up to at least $1.50USD, as that is where mining becomes reasonably profitable for me. But I do not want TAG to be a runaway as it will drive difficulty through the roof and make it hard to mine... just find a happy medium would be nice.

The rig in the photo has the pair of Dual-X cards.

Arghhh.... The suspense is killing me!  Damn revolving planet and stationary sun.  I'm awake and Fuse is asleep  Cheesy  The diff is in the 20's, the pool is cranking at > 160MH/s, we should be finding around 6 blocks an hour (and I'm sure we are) and swimming in TAG but the the front end and the back end have had another lovers quarrel and aren't talking to each other...

Where have all the miners gone? TAG is at the top of the Coinwarz list, it should be getting smashed?  My best guess is that they're all mining the latest fad coin - DOGE.  Too late guys, diff is up to 113.  I mined a couple of million whilst this pool was down when the diff was around 5!!

John,

I know the feeling... I am hoping that all is well and we are smashing TAG blocks like fiends... got to love this low difficulty... com'on Fuse, wake up.

Hate to say, but this has to get fixed. I know Fuse has poured his heart and soul into this server and we are loyal follower, but this must be a priority to get sorted and resolved. It only seems to happen when the pool starts running over 130Mh/s plus.

Fuse, what do you need to get this sort out?

The pool front-end is working again... not sure if it is because Fuse woke up or because the whale left?

No.  I'm sure he's asleep. It's like nearly 3am his time.  The frontend appears to hang when we get a combination of a long round and the whale.  Dunno, maybe it overloads the database?  The whale left, we got a couple of short rounds and the DB was able to catch up.  Pure guesswork on my part as I'm a bit of a luddite with all that kind of stuff.  Roll Eyes

Block stat confirms are still updating so I think it is just a long round.  When block stats hang at 199 or 198 confirms, you know that something has gone tits up...  Shocked

Yeah I'd love to see tag go back up also.. I was REALLY liking when it was $3/usd.. I was rich lol.

Hoping all is well with the pool. I did mine a butt tonne of dogecoin yesterday just to have 'just in case'.
