Hi, I went to a friend yesterday for troubleshooting his 8800GTX and came out as an idiot. His card hangs whenever he tries to run 3dMark/games after overclocking even by 10Mhz. His Fan was running at 60%, so I decided to change the speed with rivatuner(ntune not working on his system), though rivatuner now shows it to 100% but everest and rivatuner hardware monitor shows the fan cycle at 60%. Temps are way too high, almost 65-68 @ idle,(though i dont know whether its a high temp. or OK temp. for XFX 8800GTX). I believe if he is able to increase the fan speed he will be good to go, so can anyone suggest any application which will let the fan speed be increased in actual.
