Windows x64, 6800GT & GPU Fan Speed

So I've run into a problem since installing 64 bit windows... 3D games stutter and are unplayable. I think it's because my Gainward 6800GT is overheating, cos the 64 bit driver neglects to up the fan speed when the card processes more information. Previously, when running 32bit windows, the card would get really loud when I played games like Doom 3 or Far Cry. Interestingly, one game that doesnt have a problem is Chronicles of Riddick. I'm using the latest 64 bit Nforce drivers (77.77).
Anyway, I've tried using RivaTuner to adjust the MinFanSpeed setting, but I don't understand the syntax... Can anyone help? Is there another way/program to adjust the fan speed manually? Or should I just got back to 32bit?

Thanks!

are they stuttering as in completely stalling and regoing?

or do you get like blurred zones or just regions that don't seem to update as fast as others creating a blur effect?

just curious cause i was getting an effect like that with the new 7.7.7.7 drivers on my 6800GT and ti drove me nuts (XP pro)

I ended up saying F it and downgraded to 7.1.8.9 and everything runs 1000000x better

i'm runnin CS:S at 1600x1200 with 6AA and 8AF with all details on the highest settings. and it was running above 60FPS with very very few dips below. so i know it wasn't pure power issue.

yes, the more complex stuff going on, the more it stalls. I stops maybe once every 10 seconds for about 10 seconds. But it varies alot.
I had a similar problem in xp 32 bit when using Nforce drivers. It only went away when I downloaded drivers from Gainward. Unfortunately they don't provide 64 bit drivers as far as I can tell...
