Yeah I'm going to have to keep an eye on that. I usually get high 70s, low 80s, but with summer coming up in that sauna of a room I will have to keep a close eye. Not working on a 511 anymore, and temps are back at high 70s. Also reduced the clocks on one card that was the hottest. Fans at 65% currently so there is some room there.Chris I'd do something about the stock cooling either replace it with a HR-03GTX or crank the fanspeed to about 75-85%. I had the same issue with my GTX280 while folding with stock cooling, unless I had the stock fan cranked it would get about as high.
