cooling gtx 480 sli

[Razor Time]

But how do you go from your water temp to your gpu temp which is important?

I will be adding a water thermeter tomorrow so can perhaps answer this myself but I would love to know now.

Unfortunately mate the only way to find out is to try it. There are too many variables to take into account ie the block, pump etc.

And yes 70C on water is not good but it works and is 20+ cooler than air cooler so how cares so long as your fans are quiet?

You say from the delta graph that a double rad won't be able to keep two 480's at 70c with silent fans but how can you tell?

From that graph I reckon the water delta will be 25C so about 45C if ambient is 20C. How do you know that 45C of water is not enough to keep the 480's below 70?

It looks more like 30c to me with 1000rpm fans. If you add 30c to a water temp of 30c (summertime) your hitting a water temp of 60c which is around the limit of what a pump can take. Push the clocks further on the 480's with overvolting and again temps rise. I have found that overvolting the 480's really does effect the temps.
