Thanks for the tut. Unfortunately as soon as I boot into SL it lowers the fan speed.
As Im in bios you can hear the gpu fan increased speed, but once booted in SL it goes back to normal. Around 20%?
Any ideas? Or if someone could point me in the right direction. Thanks

I have the same issue as well. After modifying the BIOS, it does run at 100% until OS X lands onto the desktop, then it drops again.
Anyone with ideas?
