“I got some of these before the instructions link was created, and I couldn’t figure out what to do with the nylon nuts and screws. I probably eventually could have figured out how to install this fan shim, so it was compatible with the Pi-bow case, but I set them aside and several days later, instructions appeared. Excellent! The switch on the shim wasn’t really accessible with the case, until I drilled a hole in the case for a paper clip to get to it, see my review of the case below.”
“Installation was seemless and the Python script is easy to install and configure. I use it with the official Raspberry Pi 4 case without the lid. The Fan Shim easily keeps the temperature at the specified threshold.”
