Was working on my brothers computer here, and noticed the fan on his video card wasn't spinning at all. I checked the power to the 3pin connector to the fan on the backside of the card, and getting 12v to the two outside pins. I 'manually' gave the card 12v to the fan, and the fan spun up no problem. I further checked the voltage at the connector to the fan - 12v again, but no fan spinning. Only way I can get fan to spin up is to pull 12v off of a molex connector. Anyone have any ideas or suggestions?
