Graphics card fans not starting (Gigabyte HD6850/WINDFORCE)
TL;DR version: The fans on my new Gigabyte HD6850 (specifically, the variant with "WINDFORCE TM" fans) never start.
Longer: Since the purchase 3 weeks ago, I've only had time to play one fairly old game, which hasn't exactly stressed the system. After prolonged play, it appeared to lag a bit but I dismissed it as some peculiarity of my old system.
Since a few days however the game starts massively lagging within 5 minutes of starting it. Checking GPU temp gave me a shock: 103 deg Celcius. Not good.
The fans were according to ATI control panel running, but when I opened to box today while running the computer I could specifically see the fans are never moving at all...
My question is: What could cause the fans to refuse to start? System power undersupply? I doubt it's that however. Do you have any other ideas (aside from broken purchase?

Do you have the PCIe power cable hooked into the card?
Yes. Also, I don't think the card would run otherwise. To elaborate, card works fine except it's overheating because the fans aren't moving at all.
