Raspberry Pi PWM Fan Control in Rust

This is a temperature speed control daemon for your 4 pin PWM fan on a Raspberry Pi.

Motivation

I have a Raspberry Pi 4b I use with Hyperion. At times it can get very hot, ~70C. I bought a case with integrated fans, but the small fans eventually became noisy. I Switched to Noctua NF-A6x25 5V 60mm fan. At full speed it is also quite noisy. Using Python code from here as inspiration, I set out to build a program to control the fan.

    • sudo cp target/release/fan_control /usr/local/bin
  • Install the systemd unit file 
    • sudo cp fan_control.service /lib/systemd/system
sudo systemctl enable fan_control
sudo systemctl start fan_control
