A heat sink is a component that increases the heat flow away from a hot device. It accomplishes this task by increasing the device’s working surface area and the amount of low-temperature fluid that moves across its enlarged surface area.
This is a dedicated aluminum heatsink designed specifically for the Raspberry Pi Compute Module 4 (CM4).
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).
