My card is a BFG GeForce 7950GT OC. It runs at 65C idle, and that's with me setting the fan fairly high, and when gaming it gets into the mid 90s. I know that's ridiculously hot. How long can I expect this thing to last under those conditions? No artifacts as yet, and as far as I know it's been doing this for a long time, at least a few months (didn't look at the temps much before then). I cleaned out my case with air just a few days ago.
