This is a dedicated 12V cooling fan and bracket module designed specifically for the Raspberry Pi Compute Module 4 (CM4).

The fan module comes with a screw and thermal tape pack for attaching to your Compute Module 4. The mounting holes on the heatsink match the Compute Module mount holes perfectly.

A notch is included to allow for the CM4 antenna kit to be attached without obstruction, and the fan can even be used with the Official Compute Module 4 IO Board or the Waveshare Compute Module 4 PoE Board.

In testing, Waveshare found that the fan reduced temperatures by an impressive ~25C vs the bare CM4 board (your mileage may vary depending on usage and local conditions).

Dimensions: 54x39x13mm

Note: CM4, IO board and antenna kit not included.

How to Install

1. Attach thermal tape onto the CM4:

2. Fix the screws as per the images below, depending on your chosen method:
