“Great piece of kit for keeping the Pi 4 cool, the software for it works well ensuring it does its job. The circuit is built well and a decent fan is enclosed with it. If it keeps the Pi 4 cool ensuring longevity it will be well worth the money. Other fans I have seen don't have software to control them so this is far superior to them.”
“Great little cooling solution, Fits well with the Pibow Coupe case. The only minor drawback, is the fan cable, although small, can get in the way of the ribbon connector occasionally.
This drawback shouldn't influence your decision, the fan shim is a wonderful addition to the RPi 4.”
