“These fans work quite well "when they work". I have purchased and used them since 2019 on PI4's. However, for the latest order of 2, I could not get them to work on the Pi4s. I reinstalled the software a couple times and tried both fanshims from this order and a couple different pi4's. Seems like the gpio overlay is not making good electrical contact with the gpio pins. I tried putting headers on top and various other tips from the forums. No luck. The fans run continuously, which is OK from the cooling standpoint but not ok for noise and wear. I wonder if there is an issue with the latest raspberry pi OS on account of the requirement to use python venv's. Or maybe I did something else wrong. Still good hardware - quite and effective when working.”
“quiet small very easy to install. It doesn't move alot of air but think it will help alot. Also becareful the heat sink that was under it was higher then i thought and i broke my fan mounts”
“I soldered mine onto a gpio connector and use it with a heatsink.
Mostly the fan is off and the board is passively cooled, but when required it does a great job to prevent overheating and throttling.
Thanks Pimoroni.”
