I had the same problem with my GeForce 7600 GT. No matter what powerplan I
select the fan runs constantly. Running Home Premium; clean install.

Fixed by (right click desktop, Personalize; Screensaver; Change power
settings...)
1) Select Power saver
2) Change plan settings
3) Change advanced power settings, then OK. I didn't mess with any of the
settings.
The fan turned off.

Hopefully this behavior will be fixed by a driver update. I don't want my
graphics card fan on all the time. Even if Balanced or High performance is
selected.
