Easy question, I hope. I have a case with 2 120mm LED fans on it (Coolermaster Stacker w/2 4-in-3 bays), and am looking at possibly putting the 2 front 120mm fans on a fan controller, to be able to turn them off at night, while leaving the PC on. I want to do this, as the case is in one bedroom, with the door facing directly into the master bedroom, and the case points towards the door. So, the question is, if I purchase a fanbus controller (too lazy to make one), probably a rheostat based model, not a PWM, will it cause problems with the LEDs, or will it simply dim the LEDs as the incoming power is reduced, lowering the speed of the fans? Thanks. Jason A.
