Workings
This project's backend works by setting the following dtparams in /boot/firmware/config.txt. Settings require reboot to work.
The RaspberryPi 5 firmware supports up to 4 different thresholds.
The backend validates the new config and only if valid it writes it to disk.
Each threshold is defined by:
- fan_tempN: temperature fan activates at in millicelsius
- fan_tempN_hyst: fan turns off (or to lower setting) when temperature is
fan_tempN - fan_tempN_hyst. Also in millicelsius - fan_tempN_speed: fan speed in range [0, 255] where 255 is 100% fan speed
An example of the additions to your /boot/firmware/config.txt:

Defaults
The following are the default values used by the firmware:
fan_temp0 Temperature threshold (in millicelcius) for
1st cooling level (default 50000).
fan_temp0_hyst Temperature hysteresis (in millicelcius) for
1st cooling level (default 5000).
fan_temp0_speed Fan PWM setting for 1st cooling level (0-255,
default 75).
fan_temp1 Temperature threshold (in millicelcius) for
2nd cooling level (default 60000).
fan_temp1_hyst Temperature hysteresis (in millicelcius) for
2nd cooling level (default 5000).
fan_temp1_speed Fan PWM setting for 2nd cooling level (0-255,
default 125).
fan_temp2 Temperature threshold (in millicelcius) for
3rd cooling level (default 67500).
fan_temp2_hyst Temperature hysteresis (in millicelcius) for
3rd cooling level (default 5000).
fan_temp2_speed Fan PWM setting for 3rd cooling level (0-255,
default 175).
fan_temp3 Temperature threshold (in millicelcius) for
4th cooling level (default 75000).
fan_temp3_hyst Temperature hysteresis (in millicelcius) for
4th cooling level (default 5000).
fan_temp3_speed Fan PWM setting for 4th cooling level (0-255,
default 250).
