I have this guy telling me his 6990 runs at 110C degrees (after 3 minutes) when fan is working at 100%. I'm thinking that's not possible. It would shut down PC or his video signal would die. But I need to know from someone with experience. I never run these cards so hot. Edit: the guy is on eBay. I sold him a sealed card and I think he is trying to screw me. Says he can prove me wrong with a video, but it has been a long time and he has not delivered any kind of proof. Just opened a case against me and tried to waist my time. He doesn't even want to return the card, just wants $100, as if that would fix anything.
