I just wish someone would make a controller that could actually tame the fans i want to tame. This one.. still not even close to the power per channel i need which is 4amps @ 48w. Then again they are 260cfm san aces, i doubt they'll ever be particularly quiet. My current fan controller for them is a crappy old PSU that barely has the power to run 3 on full blast.. it has two settings, on and off.
