This is a dedicated aluminum heatsink designed specifically for the Raspberry Pi Compute Module 4  (CM4). The heatsink is black and 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.

In testing, Waveshare found that the heatsink reduced temperatures by ~11°C vs the bare CM4 board (your mileage may vary depending on usage and local conditions).
