“Works like a charm, especially with the python driver that autodetects the temperature and acts on the fan as necessary.
A pity that the button is not very easily acccessible when used with the piBow (would be much easier if it were on top rather than on the side of the shim.
Anyway, a fan is definitely MUST HAVE for any Pi4+4GB RAM due to thermal throttling. Plus so much fun assembling it and simply sliding it on the connector!”
