Thanks for the reply I think I'm going to send back the 3000rpm to get the 2000rpm instead. I was controlling the fan in PWM (I have to say with no particular issues) with the previous Commander Pro until the fan header went KO. I cannot say if things are related or not but I suspect yes Federico P.S. Is there an explanation for these controlling difficulties in PWM? I mean: a PWM signal is a PWM signal... what can possibly be different?

Hi, It's my first post here. I have bought a Commander Pro but I had to RMA it because fan header #1 wasn't working. I'm currently waiting for the new one, but since I have to control a Noctua 140mm Industrial 3000rpm, I'd like to ask if the "controlling problem" arises even if I force "3 pin mode" for that fan (and so voltage controlled mode) Thanks a lot Federico
