Yes, I've set my GPU fan to 65%. It reaches around 44C under load.
I've turned the AA settings down to 4x and Anisotropic down as well. I also set the ambient occlusion to saso or whatever and it seems to be running on Ultra like it did when I first installed.
Still makes me wonder why it ran Ultra with all of the settings Maxed the first day I installed the card.
Ah, well I guess I can deal with this! There isn't much difference in quality from 16x to 4x.
