I am running a PNY 9800 GT 1 GB. I have been using Nvidia system tools 6.05 to set my fan speed to manual at 60% for gaming. I then start a game MW2 in this case, and something overrides my manual setting and the fan speed drops to 0% or stock speed. There is a conflict somewhere. Has anyone been able to fix this problem. It has been the same with Vista 64 and 7 64 rc as well. I tried Nvidia support, with three replies and 2 other drivers, I am getting no where fast. I have tried 191.07, 195.39, 186.18 with no joy. I also have a "co-op" system with a BFG 8800 GT OC2 that is having the same issue. Currently running Windows 7 x64 on both machines. My temps are hitting 77c-80c with 1920x1080 AA 2x. If I force the fan speed back up my temps drop to 66c-68c.
