About this item

The EDATEC ED-CM4COOLER-B is a passive heatsink designed specifically for the Raspberry Pi Compute Module 4 (CM4), offering efficient thermal management for industrial and embedded applications. Crafted from high-quality aluminum with a black anodized finish, this heatsink measures 55mm x 40mm x 13.5mm and features a top-mount, bolt-on attachment method for secure installation. Weighing approximately 40g, it provides a lightweight yet robust solution to dissipate heat generated by the CM4's CPU, wireless module, and power management unit (PMU). The heatsink includes three thermal-conductive pads that ensure optimal contact with the CM4's components, effectively lowering the operating temperature by up to 20°C under full load conditions. Additionally, four nylon washers (1.5mm and 3mm height) are provided to prevent damage to the board-to-board connector and ensure proper alignment during installation. This passive cooling solution is compatible with all CM4 variants, including those with wireless capabilities, and is ideal for applications such as industrial automation, edge computing, and IoT solutions.
