I don't think a lot of members here have that case but wow, what cooling potential it has!!!!! I would like to get that case.
How are you giving it power? Plug the fan into a spare molex connector from the power supply. Do you have it plugged in with piggybacks from other devices? Make sure you back trace to power source.
Goddamnit, I hate this site. Too freaking slow. I'm really getting fed up with it.
