In general, PC video cards - even with similar chipsets to the ones
installed in the Mac - are not guaranteed to work... part of the reason for
OS X's  better stability than, say, Windows has been that it's only
designed to work with a relatively small set of hardware configurations -
Microsoft has correctly claimed that much of the problems that users have
with Windows can be traced back to 3rd-party drivers.

You could try attaching a heat-sink in place of the fan or replacing the
fan with another... or look for an AGP card with Mac support.
