First off let me say, I have never, and I mean never loaded my stock 5870 anywhere near 80 C. I don't know if their lab is hot, or if their measurement technique is better, or what, but I don't even arrive near that. An hour of furmark over-clocked and I can't get it much past 60 with the CCC controlling the fan.
Cliff, I remember my HD4850 with Furmark. The temperature was going easily past 90C and it was crashing every time I run it. Later, ATI added "a feature" in their Catalyst drivers to detect Furmark and throttle. People were renaming Furmark to eliminate the detection of Catalyst. I am not sure if they are still doing this with HD5000 series. But it is easy to check. Just rename Furmark.exe and run the renamed file, compare the temperatures and score.

I will admit having a single slot heat-sink as the reference design on the 4850 was a big mistake that was eventually corrected, but your right, that card on its reference heat-sink ran too hot.
Okay, so other than folding, whats an icrontic approved GPU loading technique? I want to test this on my 5870.
I have been manualy controling my fan, no wonder, but still, at 40% fan speed its not the loudest fan in my case and after five minutes its stuck at about 64 C
With the CCC taking over it shot up to 73, now thats only after a few minutes a piece, but I can see the complaint with how the CCC handles the fan ramping.
I'd like to see a simple priority toggle, quiet vs. temps, I think that would be an improved feature on a future release. I'll tolerate a little fan noise to keep my card cool.
Still, would we all not agree that this is a fundamental issue in testing? Its kind of hard to get an apples to apples comparison when each company has a different interpretation on what fan speeds should be set at to handle temps? Its its a typical blower fan, set it to an equal sound output and test there I say. Set that fermi to 24% (what the CCC was running at 73 C) and see where the Nvidia card ends up.
I'm sorry, if that thing has to sound like a blow dryer, it just has to.

They still throttle apparently, check the link below.

I will let you know soon enough...
