I can only assume i've

b) installed a Bios that causes the fan to change speed
c) Installed an audigy external, and its drivers have interferred with the setup.
One of these is probably the case, as this was not an issue for me at all, and I've installed a new bios, audio codecs and external soundcard in the last few weeks.
