Other Programs > Fan Control

RigPi 4 supports temperature sensitive PWM fan control through GPIO physical pin 32. The software for Fan Control can be found here:

https://github.com/mattrude/raspberrypi-fan-manager/

This is a C program. The source code is provided in /home/pi/raspberrypi-fan-control. It is set to turn the fan on when the temperature reaches 52C and off when the temperature drops below 45C. There is an option to set the GPIO pin number. The PWM pin number must be set in /boot/config.txt. Instructions are provided in README.md.

Fan Control starts when the Raspberry Pi boots.

The K1EL RigPi Keyer board has two pins through which a fan is connected,
