I just put my new XFX 4890 to replace two 8800GTs. When I installed the latest drivers (9.11 Catalyst) my GPU fan keeps fluctuating from 0% to 56% displayed on the ATI overdrive panel. This does not happen when on boot up so I guess it is driver related when windows loads up. I can set a manual fan speed but I would like the drivers to take care of the adjustments. Is this some type of ATI driver issue? Any help would be a appreciated.
