I'm rebuilding an old Cooler Master CM900 case with a fully populated hard drive cage in front of the front 120mm intake fan. I'm looking to replace the original CM OEM fan with something better to cool these five drives down, as well as provide decent intake into the case. This will be the only intake fan. I'm using a Cougar Vortex as the rear exhaust. Excellent fan, moves a lot of air, and extremely quiet. I'd use another for the intake, but wasn't sure if the focused air flow would be best to cool for drives or if a high-flow (non-focused) fan would be better. I'm considering the Cougar Vortex, Cougar CFD12HBB (doesn't seem to have the focused flow of the vortex), Arctic F12, Noctura S12 and F12 and others. I read where the Noctura F12 was designed for radiator use, and the S12 would be better as a case intake fan - the same may apply with the Cougars. Any recommendations would be appreciated!
