The Corsair Commander just helps clean up the cable management, also helps keeps everything in sync like the fan speeds and lighting as it can all be controlled at one time from Corsairs software. The Corsair Commander is a great piece of kit in all honestyThe fan doesn't bother me but I will probably change it on the future when I financially recover from what the steam sale has just done to me.
Why do you recommend moving it from the motherboard to the ccore? or PWM hub? just so I know.
