Please can someone tell me if this fan header is true PWM (temperature) or voltage controlled. The manual says 'quiet' fan header.
Many thanks, andy.

If it is the CPU1 header you are talking about then yes it is a true PWM controlled header.

Thank you,
I am just considering how best to control all the fans using PWM. I am thinking along the lines of a Phanteks PWM Hub controlled from the CPU1 4-pin header. |

I've heard the Phanteks PWM Hub that comes with their cases works fine. But according to what I've read, this hub actually uses voltage control to change the fan speeds. So while it is connected to and controlled by a four pin PWM fan header, its control is not PWM, but standard voltage control. That's not a problem according to the users of this fan hub. |
