Hi all, ive just bought an Enthoo Primo and connected my CPU fan to the Hub and then the Hub connector to the CPU Fan header on the motherboard, the BIOS reports my fan speed as 1200RPM so I know the Hub is working or it wouldn't be receiving a speed, now the issue is that speed will never change no matter what I do, I cannot lower it or raise it, its connected to the correct port on the Hub as it would not receive an RPM reading otherwise but it seems like PWM control of my fan/fans isn't working at all, does anyone have any suggestions or help with this please? thank you very much
