Anyone else use this controller? http://www.sidewindercomputers.com/sufanmasf.html I just got it today and having a problem. Fan 1 control knob doesn't control the fan properly it allows it to speed out of control when turned all the way down. So I have to keep tapping and holding the knob until it stays at the speed I want it at. It's fine when running full speed, but no one wants to listen to fans running full speed all the time. Is there a simple fix or should I just RMA for another? I really hate to RMA because I have to take it back out of my PC, pack it up and pay to ship it back.
