How can I read speed from my Argon fan?

[K92Pi]

Hi! I hope you're doing okay! I'm working on my Raspberry Pi project and I came across your repository. I have an Argon mini fan (link) and I just can figure out why read_fan_speed.py comes back 0 every time, even when I hear the fan spinning. Could you help me out find a way to make my Raspberry Pi 4 (running Dietpi) read and display this fan's speed?

Hi @K92Pi ,

If you want to read the fan speed for different fan you need to figure out which pin on fan is tach signal output (I use 24 for default) and modify PULSE param for your fan, which may different from Noctua's fan.
