My GPU is a BFG GeForce 7950 GT OC, with all stock cooling. It idles at 65c and when gaming it gets into the mid-90s, and those are with pretty high fan speeds. I did a case clean very recently--no dust--and the fan isn't clogged or blocked or anything. Any thoughts on (a) what the problem is and (b) how long the card will hold up like this?
