Fan does not go off if the PI is powered down

[neilyoung]

As subject says. I'm having the service running to control the fan, but if I sudo shutdown now the PI powers off, but the fan still roars. Only a complete removal of power from the PI switches off the fan. Is that by design?

I'm getting the same problem, it's probably by design, and I'm unsure if it's a hardware thing or not because it's connected directly to the pins.

But I would also like to see it powering down and the RPI is powered off!

This is by design, but you may be able to force it off by asserting a GPIO pin on shutdown.

It'll require a script in /lib/systemd/system-shutdown/gpio-poweroff that looks something like this - https://github.com/pimoroni/clean-shutdown/blob/master/daemon/lib/systemd/system-shutdown/gpio-poweroff

And drop a config file in /etc/cleanshutd.conf with:

poweroff_pin=18

I cannot confirm that this solution is working, means 120s after shutdown the fan is still running.
Maybe I missed a step.
Can you please explain what you mean by "[...] asserting a GPIO pin on shutdown."?
