I have an HP desktop with an Intel 845G chipset. Been working fine, but now I notice that as soon as XP starts the fan gets extremely slow and never speeds back up. I have tried this fan in other computers and other fans in this computer but get the same result. Also tried another power supply to no avail.
I believe it is something in the hardware fan control software that XP is using, but do not know how to look at that. Any suggestions?
