Fan refuses to go above 250 RPM

I’ve used ectool pwmsetfanrpm 5000 for testing, but fanduty has the exact same effect.

You were right. pwmsetfanrpm does work, although setting it to 250 makes the fan run like 2100RPM. Higher RPM works properly. You can get lower RPM (down to 1000) by fanduty 10

@Niklas_Berggren

set the RPM to 0 causes the sound to immediately stop, but the fan itself takes a second or two to spin down, leading me to believe that there’s either some issue with the fan controller, or the motor.

Looks like the fault is at its electric circuit, the friction of the fan is normal

@Adrian_Joachim

reported cases of fans “melting down”.
