Manta M8P and 3 pin fans
Hi everyone. I'm new to klipper (coming from reprap).
I'm struggling trying to install and configure a 3 pin Pc 12V PC case fan on my new M8P. I don't know if it's electrically possible. Does anyone configured a 3pin fan on the 4pin manta PWM connector? If so, how??
Thank you!

Is there a reason you need to use the 4 pin fan port? Why not use fan0-fan3 and just leave off the Tax wire from the fan? https://raw.githubusercontent.com/bigtreetech/Manta-M8P/master/Hardware/BIGTREETECH%20MANTA%20M8P%20V1.0%20PinOut.png

Cause i already have all 2 pins ports occupied...
You can't. A 3-pin fan is just a 2-pin fan with a tach readout. 4p ports need a dedicated PWM pin and that's not a thing on 3p fans.
You can use the power pin and the gnd pin for an always on fan, but i have a feeling that's not what you want.
