@achrn thanks for that info. i will try at 25khz and also the pullup resistor

@dc42 the label on the fan is the right one but someone said that rat ric also had an batch with the wrong label

@dc42
do you have some recommandation for an 4028 fan witch is working?

is it possible to switch it off via the gnd like descriped on the rat ric site for klipper? (sry cant post an link)

hello, i have some problems with the Fan0.

I've rebuild my printer and before it worked already with an 4 wire Fan. Now i use an sanyo 9gax0412p3s001 fan.

plus and GND connected to an Stepdown and PWM to FAN[n]- and Tacho to PB6

Code:
M950 F0 C"!fan0+^exp.pb6" Q250
M106 P0 S0 L0 X1 B0.1

The Fan is working and controllable but is spinning at 0 already. I checked the Forum and someone sad the fan could be with the wrong label.

Would an 10K pull up help?
