I know this has been mentioned before. Does anyone else experience fan speed slow down when driver loads, then speed up to bout mid speed when GUI starts? I mean, it isn't unbearable, but the fan hum is just annoying. Any solutions?
What card do you have? Is there a passive alternative? I'm using the Apple branded 7300gt and it has no fan.

I'm on a 7800 GT btw. Looks like it's BIOS flash time XD.

I would actually want to increase my fans speed!

When OS X nv drivers are loaded, it first sets fan speed to rom 2D mode, then desktop loads and switch to 3D mode. This is because OS X ALWAYS uses 3D mode.
In PPC macs, only ATI cards have fan speed control with ATI's software (ATIdisplays) - at least for X800XT/X850XT...
nvidia cards in PPC/intel macs just run in 3D mode all the time, so it means full voltage, full speed and fan at 3D speed setting.
If you don't use 3D, just flash your card with an edited rom with lower fan speed (using nibitor is the easiest way to do it)
Or just use a 3rd party cooler with thermal sensor or manual fan speed control.
I just run a Zalman VF 700Cu on my 7600GT, and plug it on MOBO case fan connector so it is controlled by the BIOS. It's not the perfect method, as fan won't speed up unless case temperature really increases, but VF700Cu dissipates heat fine, even runing at 15 or 20%...
Newer 3rd party GPU fansink just use a thermal sensor, so it's even better...
