Since switching to a minimal #Debian install for my #RaspberryPi 4, I've been pleased with the overall performance, and it's now also running #Plex.
I do miss the easy config of my #GPIO fan. Previously I easily set it to come on when the CPU reached 55°C, but I can't figure out how to target it manually from the #terminal. I'm happy to write a #Bash #script for the task of monitoring and triggering the power. But I can't do that until I figure out the commands.
Any ideas?

Yeah should be Python installed (if not, I could easily install it). Is pwm a module?

It's basicaly, fast on and off switching, with a variable on part (0-100%) allowing you to control the fan speed.
But the pi can only switch the 3v3 pins and only with some mA. So i soldered a transistor etc. to switch the 5v supply. You can easily find such circuits on the net.

Do you hava Python on it?
If so you could even controll the speed with pwm
