3 SFLEX 1200 RPM in the middle
2 Arctic 1500 RPM in the rear (these things push serious air)

It's not super quiet, but it's consistent. Most of the noise's from the Arctic fans pushing God knows how much air around. The raptor's aren't half as annoying as when I used the old Stacker HDD module though.
