Silent and High Performance

The CM1 is a silent, fanless, passive heatsink kit for the Raspberry Pi Compute Module 4. We like our quiet time and attaining the best performance possible so we designed this kit to have the best of both worlds.

The heatsink is made of microforged aluminum with fins that are designed with maximum surface area. The tall square fins allow ambient airflow to pass in all directions and are well suited for natural convection.

The 3D printed mounting bracket is designed to not interfere with the WiFi signal and provides enough clearance for an external u.FL antenna to be installed.
