Fan control with nouveau controller ?

[Linuxguy123]

I'm running a fully up to date F14 installation on my laptop. 

For various reasons today I uninstalled the nvidia driver and installed
the nouveau driver.   My laptop has a GeForce 8800 GTS video card.

Everything works but I can hear the video fan running constantly which
is annoying and wasteful of the battery.

How do I get the video fan under control ?

Thanks
