Hi, Using compiz causes the fan on my Nvidia cards to operate. I leave compiz turned off - it sometimes interferes with other 3D apps like GoogleEarth, Bleander, etc(all of which also cause the fan to come on). In my experience, anything that is graphics intensive - and relies on hardware acceleration - will cause the fan to operate. YMMV.
