“Great product, I have the Horizontal version to be able to fit it into the case (just, love how compact this is) between the Pi & the Fan mounted on the top. This has saved a noisy fan from running all the time while preventing it from getting too hot.
Just to add there is the Fan option within Pi > Preferences > Pi Configuration, switch it to Enabled and set to GPIO 3 and that will also update the config.txt file as described above, I also set mine to start up a few C lower than the 80c default.”
