“While the fan itself is very quiet, the mounting-system is prone to vibrations. I have yet to find a proper solution, but as it comes you will definitely hear the fan as it kicks in and the difference when it shuts down again. The python library that comes with the shim has both a python module to play around with and a script to install a systemd-service for cooling which is super convenient! From what I saw the code is very clean and the systemd-service allows you to customize: - temperature-related turn on/off with threshold - led on/off and brightness - set the button-press times and/or what it does If you prefer you can write your own implementation or fork the fan-shim lib to customize the hardware. If or when I find a solution for the vibration I will give it 100%.”

“I don't know, maybe I got a defective item, but it stayed silent for a couple hours and then it got very noisy and vibrates when it's on. I'm not removing it just because I need the cooling, but if that's the level of quality I should expect then I'd rather buy a good passive heat sink”

“The fan is working well, also using the sw to set the start and stop temperature. The fan however is not completely silent, and during the evening hours it can be heard”

“Just put it on the gpio header and you're good to go. When idling the processor shows around 37 degrees celsius, under stress it doesn't seem to go beyond 57 degrees. Button, led, fan speed can all be controlled and customised using the python library. UART pins 14 and 15 are not obstructed so serial console works without issues. The pibow case for the Raspberry Pi 4B is made with this fan in mind so it all comes together perfectly.”

“The RPi4 runs hot and really needs cooling. With an RPi4 in a Pibow case this shim was a very poor fit on the pins. When installed the fan runs (and is reassuringly quiet) but there was no speed control and no LED lighting. By jiggling the shim about it was possible to achieve both speed control (cutoff below a certain temperature) and observe changes in the LED colour. However, the fit was never permanent and infuriatingly temperamental. The GPIO pins on the RPi4 were perfectly straight and true (never used for anything else) and probably needed bending to make proper contacts with the shim. I wasn't prepared to butcher the RPi4 to achieve this and bought an alternate case with an integral fan (for less than the fan shim!) which runs cool and quiet. The fan shim does cool the RPi effectively, but the 'advantages' it offers over less expensive alternatives (control etc.) rely upon the correct fit ... which it doesn't.”
