People are having this issue with EVGA and Gigabyte as well; as I have seen on Youtube.
So far there hasn't been any red screen, and my computer has been on and under stress since this morning, around 10am EST.
Playing games right now and no problems. I know my card has amazing temps (ranging from 40c to 60c) and up to 72c if I am playing a heavy game like Battlefield 3.
I feels like GPU Tweak and/or GPU-Z was the problem. I remember reading somewhere, it had something to do with temp monitoring software messing up the BIOS of the Video card.
