As many know, the Raspberry Pi 4 can struggle with high CPU temps and overheating. I've designed a simple fan mount to attach a 30mm fan to your Pi to help cool it! There are a few versions with 2 or 3 screw mounts. There are versions to accept m2 (or #2 machine screw) and m2.5 for the board-mount screws. The fan screw holes are all m3. You'll need a 3v or 5vDC 30mm fan as well. We just had the fan wired directly to 5V and GND but you can write (or find online) a script that will control fan speed based on the CPU temperature.

To connect the fan to the headers, I soldered breakaway [female headers](www.digikey.com/short/zcm314) with 0.1" (2.54mm) spacing to the fan wires and plugged them in. Make sure you use the correct pins and note the polarity!
