FurMark is the ONLY program that I can get the fan to kick up to the point that it's audible. Even then, if I were to push the fan to 100%, the card would cool down into the low 60's C.
What Nvidia is asking the consumer to do in terms of heat dissipation is flat out ridiculous. The first person that doesn't have proper cooling in their clunker case for this card is going to fry their entire computer. This is not a good situation for Nvidia. They're so desperate to salvage some money out of this that they're putting people's computers at risk.
I agree with your assement.
I was disappointed when I first installed the 480 GTX in my system for testing. I had a hunch that it would not be able to match the 5870's efficient cooling system.
The tables have turned and NVIDIA desperately needs to spend more on R&D or make agreements with other companies in designing a high-efficiency and effective cooling system. It will cost them, but the days of drowning out fan noise by using headphones are over.
