I need some advice on a fan controller. I had originally planned to use the built in fan controller on the trooper, however I did some test runs during the mockup and the fans had a sort of pulsing noise to them. Upon investigation I have found out that the fan controller on the trooper is a pulsating voltage fan control. For lower speeds the controller sends out a voltage pulse with a longer time interval between each pulse, something like that, this is not ideal. I don't have drive bays so simply putting in a drive bay controller is out of the question and I would like to be able to controll all fans with one "knob" or a system like what is built into the trooper. Any ideas? I can mod a drive bay controller to fit into the case but I still don't know which one to get.
