Raspberry Pi 4 Fan Mount **Backward Compatible!**

thingiverse

As many know, the Raspberry Pi 4 often encounters difficulties with high CPU temps and overheating. I've designed a simple fan mount to attach a 30mm fan directly to your Pi in order to help cool it down! There are several versions available that come equipped with either two or three screw mounts for added stability. These variations also accommodate m2 (or #2 machine screws) as well as m2.5 for the board-mount screws, while the fan screw holes remain consistent at m3 dimensions. To effectively utilize this setup, a 3v or 5vDC 30mm fan is required, which can be directly connected to 5V and GND without any additional scripting; however, users may opt to write (or find online) a script that will control the fan speed based on the CPU temperature. To establish a secure connection between the fan and 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 seamlessly. It is essential to utilize the correct pins and take note of the polarity to ensure a safe and efficient setup. A recent update was made on February 27th, 2020, adding a new 40mm mount design that has yet to be printed or thoroughly tested. To explore more options for your Raspberry Pi, users can find 30MM fan selections [here](www.digikey.com/short/zcm3w5) and 40MM [here](https://www.digikey.com/short/zqvdnm).
