What are your gpu temps with a waterblock?

post #1 of 13
Thread Starter 
I purchased a 79x0 heatkiller block, will take 1-5days till FrozenCPU has it in stock and then ships it to me.

I currently have my card very cool, its a his 7970 iceq2, seems it idles 39C and loads up to 62/65C under heavy stress tests, OCCT pushes it to 74C after a few minutes

What are your temps? Do you think I will see guaranteed temp drop by watercooling mine? Reason I ask is because maybe I can save $200 smile.gif it was quite expensive for the block+backplate and I don't want to go through with it if i'm only going to see a 1-2C temperature drop.

You guys know best, help me out! I'm sure I can still cancel the order since it hasn't packaged or shipped due to not being in stock.

Generally GPU temps, assuming proper raddage  / water flow, would be in the 40-50C range under load.

My 680 idles at 22C and maxes at 30C.

My 7970, which runs three 23" monitors, idles at 35C and maxes at 47C.

You're going to notice, mostly, a smaller delta, and that's what is most important.

Low 50s, but she's taking alotta volts.

3970x @ 4.7GHz 1.4v and a GTX 480 @965MHz 1.24v. All on 480mm worth of rad.
