I just installed an eVGA GeForce 7600GT video card in my new Vista Ultimate x86 RTM computer. The GPU fan runs almost silently until just before the Vista logon screen when it kicks into high gear and stays there. I have the drivers for Vista RTM (97.46) installed. I've looked in nVidia Control Panel help and found a reference to controlling the fan speed and GPU clock, but those settings don't appear to actually be there. Is there any other way to control the fan speed? I'd also like to monitor the GPU temp.
