hey I got three of these and am happy as a clam, with the controller knob at 12 o'clock they run at exactly 2400 rpm and they are really quiet, maxxed they are a bit noisy - but not bad at all
the controller fits in a case slot and the cables are long enough for my biggest cases
comes with a grill and all the screws too
great price
