Okay so I have a 6 inch ram mixed flow, with ram controller, the issue is when reducing the fan to 50% on the low setting the fan whines like a bitch, 50% on the high setting and the propellor inside wobbles like hell...is this normal or faulty? Also where my outtake pipe is the noise is like a jet engine and very loud is there a way of deepening the air flow noise?
