Change fan speed in nVidia control panel?

Is there anyway that I can set the fan speed to 70% in 2D, and 100% in 3D gaming sutomatically?
As far as I know fan control speed has been broken in the NV control panel for a while now. Use rivatuner to control your fans.
the newest drivers let you change the fan speed on the 8800s again :D YAY!
Im confused now. Latest ntune has fan control? This is for vista 64 on my system. Is this for xp only?
nice, I didn't know they fixed ntune's fan control speed, im still not going to use it as I like Riva tuner but its nice to know nvidia can fix things lol.
