Re: Higher idle temps on 6800GT
It's been known for some drivers to raise temperatures, however, that usually isn't the main problem. You say there isn't dust blocking the fan, but did you actually remove the card from your computer, then remove the faceplate that covers the heatsink area? The dust doesn't build up inside the fan, but outside the fan on the fins of the heatsink. In other words, the comes in thru the heatsink and out the fan (blowing away from card instead of onto card). 6800 cards are well known for dust build-up in the heatsink. Besides, these cards do run warm anyway, but you shouldn't have to worry about it overheating, it'd have to get pretty damn hot to notice any weird behavior from it.
