[BUG] Artillery Sidewinder X2 Controller Fan not working

[Schalonsus]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

With stock firmware the controller fan starts spinning when heat bed is over 50°C or stepper motors are working
With bugfix-2.1.x there is only a clicking sound from the controller fan, never turns on
With 2.1.2.1 the controller fan starts spinning over 50°C but then stalls and just make clicking sound

I lowered #define CONTROLLERFAN_SPEED_ACTIVE from 255 to 240 and then the controller fan is working like expected

Interesting. 255 is max speed, so it should work better than 240.

Is there any chance his logic levels for the fan got inverted?

[Schalonsus]

With 2.1.2.1 it starts spinning full throttle and then stalls, so logic should not be inverted
Maybe overflow error (value too big) or 255 draws too much amps and the board cuts power?
Strange is the clicking sound with 2.1.2.1 and Bugfix 2.1.x when not spinning
