I have a 120mm Sharkoon '2000' cooling my processor and three 80mm Sharkoon '2000' cooling the chassis.

The 80mm fans are being slowed down by the Q-Fan thing to about 1300rpm which makes them all pretty quiet, however the 120mm fan always runs at full blast?

All the fans are three pin so I wonder why Q-Fan can't work its magic on the CPU fan?

I see it has a 4-pin header (PWM) connection but that should make the Q-Fan work a bit more accurately than a 3-pin, it shouldn't mean a 3-pin can't have its speeds adjusted at all?

Anyone got a 3-pin fan to work with Q-Fan on the CPU header?
