Re: Geforece Go 7600 fan problem
I believe that most people have not had success using the 3.30 bios and are sticking with the 2.40 bios. If you downgrade to 2.40 (assuming that's possible with your model) the attached DSDT.aml causes my 7900GS Go card's fan to work. If you are running Ubuntu, simply unzipping the file and putting it into /etc/initramfs-tools, running "sudo dpkg-reconfigure usplash" and rebooting should make everything work.
(The usplash thing is just a simple way to force the rebuilding of the initrd for the currently running kernel. There are many other ways to do this but, this is the one I always remember).
