Waveshare Aluminum Heatsink for Raspberry Pi Compute Module 4

The Waveshare Aluminum Heatsink for Raspberry Pi Compute Module 4 (CM4) is a compact, purpose-built cooling solution designed to help manage heat during demanding CM4 applications. Made from durable aluminum, the heatsink provides efficient passive heat dissipation while resisting corrosion and oxidation. Its 55 40 5 mm dimensions are tailored to the Raspberry Pi Compute Module 4, with mounting holes aligned for a secure fit.

The antenna notch allows the CM4’s wireless antenna area to remain unobstructed, making it suitable for wireless CM4 configurations and compatible baseboard setups. The heatsink weighs 0.028 kg (28 g) and comes with screws and thermal tapes for installation. Waveshare’s testing indicates that its dedicated CM4 heatsink can reduce operating temperature by approximately 11C compared with a bare CM4 board, although actual results can vary with workload and operating conditions.
