Help me setup dual gpu cooling?

post #1 of 11
Thread Starter 
A bit of a WC'ing noob. Anyways im trying to help my friend. He wants to water cool only his GTX 480's in SLI but im unsure about what size radiator I would need, what kind of pump, and all those other things. Would anyone be nice enough to link me a build for it? He has a HAF 932, that should make it a bit easier with choosing certain components.

For my build, I will have an i7 920 and three GTX 480 using a 480 and 240 rad. For SLI 480, I would say a GTX 360 would work. I'll take a stab at a build:

1x GTX 360
3x AP-15 for the Noise Conscious or San Ace H1011 for Raw Power Fan Controller Recommended
2x EK 480 WB
1x MCP355
1x XSPC Acetal top
1x EK 150 Basic Res
8x 1/2 3/4 Compression Fittings
2x Angle Adapter Needed to hook up compression fitting to reservoir
1x SLI Fitting Add the Crystal Link Tube specific to slot numbers
5x 1/2 3/4 Clear Tygon Tubing

Couple things. The compression fittings make it a bit more expensive. However, I've never used barbs so I don't know much about sizing and how to use them. It's also a lot to put out there for someone as new as you, so make sure you and your buddy reads up on installing it. Lastly, I didn't know the spacing of your video cards, so you have to choose the SLI link tube that works for your build. Other than that, this is the general gist of the situation. I'm pretty sure others will have better ideas. This is just my take. Hope it helps.

Anyone else have any recommendations? I was thinking a dual bay res with a pump already in it.

I'm just cooling my gpu's at the moment also. Here's what I bought:

http://www.frozencpu.com/products/12...l=g30c321s1310

and

2 of these (I have 470s)

http://www.aquatuning.us/product_inf...FC480-GTX.html

overnight shipping from germany was only 8 bucks!

and the finished product:



gpu's idle at 30c and no more than 50 at load

I use the 1.5 X GPU rule. So a 360 rad and a MCP355 pump should work great. Swiftech micro resevoir.

So far im looking at:
http://www.frozencpu.com/products/10...07s152#options
pump/res

http://www.frozencpu.com/products/42...?tl=g30c95s161
radiator

GPU waterblock x2
http://www.frozencpu.com/products/10...0c87s143#blank

http://www.frozencpu.com/products/10...-13.html#blank
fans x3

http://www.frozencpu.com/products/11...oir_Strip.html
kill coil

http://www.frozencpu.com/products/11...ive.html#blank
pt nuke

Now im unsure about which compression fittings I would need and whatever else besides tubing. Also instead of using a 360 rad, would it be fine to use a 240? He's only cooling his GPU's so I don't see why not.

Sure a 240 may work, but you may not get optimal temperatures. You'd probably have to get some higher RPM fans to offset the lower amount of radiators. The 480s do run hot.

Also, with the radiator you've chosen, I don't think low speed fans will do. You will have to get the SR1 radiator designed for lower speed fans. If you want to stick with the stealth, you'd have to get higher RPM fans.

Oh, alright. Then i'll pickout some higher RPM fans. So what should I pickout for fittings, etc?

You would need 2 for the radiator, 2 for the pump/res, 2 for the top and bottom of the GPU blocks, and an SLI fitting for both. So that is 6 fittings and 1 SLI fitting. You can grab 6 of these 1/2ID x 3/4OD Compression Fittings and one EK SLI Bridge. If you have a further spaced SLI setup, grab the 3 slot EK SLI Bridge

Then just choose the color you want of 1/2ID x 3/4OD tubing

Fittings is personal choice. Barbs if you want to go the cheaper route just make sure you zip tie or clamp them. A lot of folks like 7/16" ID tube over 1/2" barb for a tighter fit.

If you go compression fittings, you need to choose your fittings to match BOTH the ID and OD (inner and outer diameter) of the tubing. So if you go with a tube that is 3/8" ID and 5/8" OD just get the compressions that match the same measurements.
