    Maximum Fan RPM

    Hello,

    I'm having an issue with one of my fans. I have a Noctua Industrial PPC 3000 RPM, 12V PWM that was working just fine with my old Crosshair V Formula Z goes up to 3000 RPM (quite noisy and noticeable but giving a lot of pressure).

    Now with the C6H the maximum speed it reaches is about 1500-1600 RPM no matter how I set it through the BIOS - PWM or Voltage mode, turned off the power management, maxed it out, nothing helps. The fan is connected to OPT 2 as it's closes to the front panel.

    Any ideas what could be wrong?

    Hello

    I'm not sure what OPT 2 is. If you are referring to the CPU_OPT header it is slaved to the CPU_FAN header and cannot be configured independently.

    My mistake. It's actually CHA FAN 2.
