I have been testing various voltages for my GTX 470 to try to reduce the heat. I got it as low as 80 degrees with the fan at 80% with a custom fan profile. This was not a good solution (but still better than the 94 it got with the stock fan profile with the fan still at 50%!)
So I varied the voltage little by little. It started at 0.96v and while running Furmark I lowered it until I saw artifacts and crashed. lol. That occurred at .862v, so I raised it one notch to .8750v and ran it for one hour on Furmark at that voltage and saw no artifact and no instability. And it was able to bring the fan down to 75 degrees at 70% fan speed. I'm sure with a little more tweaking of the fan profile I can get it better.
Is my one hour test on Furmark enough of a test for stability?
