I just recently RMA'd my second Commander Pro because it stopped working. I have posted this same question/thought to Corsair support and i'm waiting for a response. I have Noctua fans that were working fine with the commander pro till recently. I really like the commander pro as I can fine tune case performance to the application. As I haven't found anything similar in the sector.
NF-14 IPPC 300 pwm
My fan specs:
3 phase motor
max input power: 6.6W
max input current: .55A
As with these specs I should be able to run 3 within the threshold of the commander pro, right?
Also I wonder of getting the NA-FC1 fan controller from Noctua to act as middle man and send the pwm/rpm to the commander pro(if I read the features right) so I can theoretically control the fans in ICUE.
