I just installed my first graphics card that has a fan. Within the first half hour I noticed the card is extremely hot but the fan is not spinning.
Is there a trigger in the graphics driver that switches the fan on & off, or is the fan supposed to spin constantly? (in which case it sounds like a defective card) The card is a used VisionTek 1550PCI256 from ebay, runnning under Ubuntu Linux 10.04
It should start up when you power on the PC, if it is not powered up make sure the little 2 wire power connector for the onboard fan is connected on the video card. If that is connected and the fans still don't spin you will need an RMA.
