cannot adjust fan speed for OC'ing on my GTX260
I'm not sure what the deal is, but I cannot adjust my 260 fan speed at all. I've tried rivatuner, EVGA OC utility w/o any success. I was using the EVGA OC utility that came with my card and everything was ok.......until I upgraded my video driver. I've unistalled, reinstalled several diiferent drivers, unistalled and reinstalled the OC utilitites and still no fan control.
Anyone have a suggestion? Frustrated........
