Description Waveshare-25939 is the Official Raspberry Pi Active Cooler for Raspberry Pi 5, built for Raspberry Pi 5 thermal management with a single-piece anodised aluminium heatsink, a temperature-controlled blower fan, pre-applied thermal tapes, spring-loaded push pins, and a 4-pin fan header cable. It is designed to keep Raspberry Pi 5 comfortable during heavy workloads such as edge computing, embedded Linux services, AI demos, media servers, camera processing, robotics, and long-running maker projects. The cooler follows the Raspberry Pi 5 board layout and mounting holes, so installation is compact and clean: remove the thermal-tape backing, align the heatsink over the Raspberry Pi 5 heat sources, press the push pins into the dedicated holes, and connect the 4-pin cable to the FAN header. PWM speed control with tachometer feedback allows the Raspberry Pi 5 to regulate the active cooling fan according to temperature and workload.

Dimensions 63.50 x 42.50 x 13.70 mm Mounting Spring-loaded push pins Heat Transfer Pre-applied thermal tapes Applications Raspberry Pi 5 thermal management and active cooling Edge computing, AI inference demos, and computer vision prototypes Home server, NAS helper, media server, and dashboard/kiosk builds Robotics, automation controllers, industrial prototypes, and embedded Linux systems Long-running Raspberry Pi 5 development, testing, and maintenance benches Compact projects that need an official low-profile heatsink fan solution Product List 1 x Official Raspberry Pi Active Cooler for Raspberry Pi 5 Other Content Install the active cooler only after powering off the Raspberry Pi 5. Check that the thermal tapes are present and undamaged, align the heatsink with the Raspberry Pi 5 mounting holes, press the spring-loaded push pins evenly until secure, and connect the cable to the FAN header in the correct orientation. Keep the fan intake and exhaust area clear for stable airflow. For best reliability, use the Raspberry Pi 5 official active cooler in a ventilated enclosure or open build. Repeated removal is not recommended because push pins and thermal tapes can wear after removal. The metal heatsink may become hot during operation, so allow it to cool before handling.
