I went from 82c idle to 55c at 35% (room temp is over 30c though). Any more than 40% however is too loud for me. At 50% it sounds like a vacuum cleaner and at 100% like a fighter jet taking off!

Question: Are idle clocks working as they should? When GPU activity is 0% my GPU clock drops to 500Mhz and Memory clocks stay the same.

Also, which is the best program to stress the GPU?
