“perfect for the rasp pi4. even though i updated the firmware to reduce the temp of the new pi4 i felt that i should also mount a fan and fan shim is perfect for this. very simple to construct and a perfect fit when used with the pibow coupe case it requires no soldering. can be fitted with no additional software and it will simply run or you can download the software and program the fan to come on at a threshold you set. even has an led light to let you know what's going on with the temperature. brilliant and inexpensive. highly recommended.”
