fan stops working

General
1

fan stops working when pifi starts up, with raspbian it works fine. is there a reason or is it a bug?

2

The fan is not “always-on” on PiFi it should be coming on certain temperatures

When booting up/first install the fan does also turn on

It’s controlled I believe in /boot/config.txt

dtoverlay=gpio-fan,gpiopin=14,temp=80000

So 80°C would be the default for turning on with Pi4, on Pi 5 I think it works like this:

  • At 60°C: The fan turns on at a low speed.
  • At 67.5°C: The fan speed increases.
  • At 75°C: The fan reaches full speed.
