SLI GTX580 WC Questions

post #1 of 5
Thread Starter 
Hey all,

I've asked a similar questions over on the EVGA boards but was just hoping to get a few more responses here.

I've just ordered my pair of GTX 580 HCs from EVGA. Im currently running a 920 @ 4.0 on the EVGA classy and the CPU and chipset are both liquid cooled. Im currently using the Black Ice 360 GTX.

With an additional 120 rad on the exhaust fan up top, do you believe I'll have sufficient cooling capabilities for the 2 cards and the cpu / chipset?

Thanks.

It really depends on what fans you are using. If you are using 3000 RPM fans you could run everything off just the 360 radiator easily. If you are using 1500 RPM fans even with the added 120 it would not be ideal.

Let's look at the results from Skinnee Labs radiator testing:



Now, i7 = 150w, 275w each on the 580s, and 50w for chipset. That gives a total of 750W. Now, you want to aim for a water-air delta between 10C and 5C. With the single GTX 360 radiator you could get a 6C delta with 3000 RPM fans, or an 10C delta with 2000 RPM fans. It depends on how much noise you can tolerate and what temperatures you want.

If you add in the 120 your will drop the above figures by 1-2C.

Thanks for the prompt response - looking at this I realize there's a whole wealth of knowledge I'm not even close to understanding yet. I'll give all of this a look.

FYI - the GTX 360 is currently using 3X scythe slipstreams (the 1900RPM model) and I'd use the same for the 120.

Okay, so you will have around an 8-9C water-air delta, which is pretty good for such heat producing components.

Outstanding - time to order parts! Thanks again. Cards / AX1200 should be in tomorrow and I'll get the new rad sent this week. I'll have updates soon as I can.
