Sapphire 7970 oc w/ boost fan turns off

post #1 of 4
Thread Starter 
I got a second 7970 and I noticed that the fan turns on and then off when I boot my pc. Any ideas why this is happening?

ZeroCore technology in AMD crossfire. To save energy, the second card turns completely off, and turns back on when its needed under load.

there is also a feature on my msi 7970 pe that spins the fans backwards then stops and starts them forward to remove any dust buildup. Sorry i read about the feature on the website but i dont remember its name.
