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