Troubleshooting • Re: How to change PWM fan control mode

Is there a way to have the fan be manually controlled? I've seen people unload and load modules to get access to it but there must be a more clean way to do it.

if i cat

Code:

/sys/class/thermal/cooling_device0/power/control

its set to auto.
If i cat

Code:

/sys/class/hwmon/hwmon2/fan1_input

i can see its RPM, pwm1 to see the current pwm value. When i echo a value into pwm1 it does react but then after a few seconds goes back to what speeds are set using dtparam.
