Nvidia 9800 GT (1024 MB edition), Using EVGA Precision. When I play BFBC2 I will change my fan to 75% on my videocard, usually around 20 minutes later the fan will go back to 35% and I won't be able to change it and if I can it will go back to 35%. I tried to solve the problem on my own by updating drivers. Did not work. Any Ideas??

Windows 7 Home 64 bit.
Idle temp 50-55 C
With fans at 75%, 65-70 C
With fans at 35%, 90+ C
