I have played too much with the fans and I made a short-circuit a few second, now the cooling parts fan is always spining at 100% speed, I am not sure if it is a motherboard issue, maybe it come from the software.
If I change fan speed by gcode I can eard that the fan speed change a little but still around 100% (I do not have a signal analyser so I only measured the DC voltage and it vary from 19V to 24V) , I tried Marlin 1.9 and Marlin 2.0 with different settings without success.
Here is my question, if it come from the harware, is there a way to change the part fan cooling pins ?
I have probably burned something on the motherboard :(

Hi, If you are referring to a cooling fan, it should be in a normally open state when the printer is turned on.
