Hello everyone, I hope you all had a Merry Christmas.
I would like to equip my RPI4 with Moitesier Hat2 with a cooling fan (in the Tyrrhenian Sea it is quite hot in summer), which fan should I buy? How should I go about connecting it?
Currently the RPI4 with the Hat is mounted in a Rooco case, which case should I buy to also insert the fan?
Thanks for your help and a happy new year to all forum users.

Hello,
I have tested a fan on my MOI-HAT 1.
It didn't work very well for me because the magnetic field of the motor deflected the compass.
I manage well with heat sinks and avoid heat from outside.
Greetings Jürgen
