Affordable Cooling for Cards?

[2D]

I've been looking into something like this:

http://www.arctic.ac/en/p/detail/index/sArticle/502/sCategory/2182

Does anyone have any experience with this product?

today I just ordered 3 Accelero Xtreme II for my 7950s (with EK adapter, it will fit the card no problem)
It's on clearance sale  
I'll let you know the result.

It should cut down on power consumption by a huge margin. 79XX series benefits greatly from water cooling.

They should work well, I have a couple of those on the Nvidia cards I use for gaming. A bit pricey for Bitcoin rigs though. I'm a slave for price/performance ratio so I'm just using a couple of huge old fans.

well, at the price of 45 each I guess is reasonable

I was halfway down that road, and changed my mind.
I am still not comfortable to use water around rigs

IIRC, the power savings from a watercooled 7970 was because the waterblock keeps the VRM temps as cool as the GPU core, which runs more efficient. This Accelero does not do that, and people often times see higher VRM temps.

This one from EK looks really cool equipment http://www.ekwb.com/ ... and they have support for dual gpu cards water cooling
Also they have a nice cooling configurator at http://www.coolingconfigurator.com/ ... did someone tried their watercooling ?

true for Full cover water block, but not for GPU core.

OK, after several hours of work I put xtreme Plus II on 7950 and let the glue dry overnight.

three cards have temp of
66, 61, 54 @ less that 50% fan

VRM temp (I see two VRM sensor on each card)
81, 78
69, 73
69, 74

TPU shows cards are running at 0.96v (I set in MSI AB @ 1.06v)

and the result is mining scrypt coins, so I guess you will have better temp if it's SHA256 coins.
hope this helps.

I'm think i need an AC, because i have 20" fan facing the rig and temps still go up to 90C... I can't cut a whole in garage, it's a condo so not much i can do and there's no window.

I was thinking:
http://www.walmart.com/ip/Haier-Mini-5-000-BTU-Mechanical-Window-Air-Conditioner-HWF05XCL-L/17477197#Item+Description

then enclosing the rigs into some kind of 'box' and point cold air from the AC into it(using some kind of hose or something), so the cold air ony goes directly to the enclosed box where the rigs are, then big fan sucks out all the air of the box.

here's the mockup:



Do you think it will work?

I'm also concerned about the power consumption to run AC 24/7, what do you think it will be if my rate is 0.11 per kwh?

Thanks!

I put 3X 7970 directly in the line of fire of my AC w no case and some risers, works like a charm hottest card is 72C.

Disclaimer: only works with a blower (reference) style fan.

If possible, remove the metal grate from the card exhaust in order to improve the air flow.


In many cases this is not possible as the metal plate is used to secure the card, but it can reduce the temps with few degrees.

A step further would be to attach on the same end a fan to help pulling the hot air outside, (a push-pull configuration).
Something like this:


With this combination I have reduced the temps with about 10C (running at 60C now).

Yep, forgot to mention. I will add exactly that.

anyone any ideas on this mockup?

Why don't you put the cold side of the AC in the box.  Your garage will still get really hot of course.

I thought about doing exactly what you have drawn up here. I haven't done it yet but was thinking I would build the box out of that blue Dow Styrofoam 4x8 sheet insulation probably 3/4". Use Aluminum Ducting tape to tape off all the corners http://www.homedepot.com/p/Nashua-Tape-324A-2-1-2-in-x-180-ft-Cold-Weather-Foil-Tape-3240024500/100048600 .
You may or may not have to build some sort of wood frame for it as the 3/4" sheets are pretty riged. Building the box out of the styrofoam would make it light and easy to move around or out of the way.

As for the A/C you can stop by Wal-Mart and look at the unit most of the time it will tell you the energy consumption on the signage.

A little window unit draws like 500 W.

I have been thinking of using a kitchen-vent. The kind you have above your stove.
It should create a draft that sucks in fresh air all the time. To make it more efficient, a box/skirt could be added to make sure the air is drawn in from as low as possible. (cold air sinks).
-Not totally sure on how they cope with being always on though, but a duct fan should also do the same job.

You have to make sure that there is enough air coming in so that you don't create a low-pressure where the fan will struggle to move air out, but the garage probably has some vents already.

BTW: you might wanna add some form of light material at the vents to filter away some dust/pollen etc. - Like polyester wool for loudspeakers.
