I'm afraid that manually setting the speed is not possible (or we don't know how to, since we Asus has not documented their interfaces for this). Maybe there is a fan profile selection option somewhere in the BIOS settings, which influences how aggressive the auto settings ramp of the fan ? > PS. When I set 0 into pwm1_enable. Fan speed is near 6000 RPM. Ok, so that shows that switching between max and auto works, other then that there is unfortunately little we can do.
