The Active Cooler is a single-piece anodised aluminium heatsink with an integrated blower. It has pre-applied thermal pads for heat transfer, and is mounted to the Raspberry Pi 5 board directly using spring-loaded push pins. It connects to the same 4-pin JST connector as the case fan.
A radial blower, again selected for low noise and extended operating lifetime, pushes air through an extruded and milled aluminium heatsink. The cooling performance of the Active Cooler is somewhat superior to the Fan Case, making it particularly suitable for overclockers.
NOTE：Blowers are electromechanical systems that direct air towards a specific direction using a fan and designated channels. While fans displace large volumes of air and promote circulation within a designated area, blowers provide a degree of air pressurisation to drive it out and forward.
The Active Cooler has not been designed to be repeatedly removed from the Raspberry Pi 5.
Efficient Temperature Management:The Active Cooler for Raspberry Pi 5 effectively reduces idle temperatures from approximately 65°C to a much lower 45°C, providing efficient temperature management during normal usage.
Sustained Cooling Under Load:During extended testing under load, the Active Cooler's fan operates at low speed, stabilizing the CPU temperature at 60°C. This ensures sustained cooling, with maximum temperatures reaching only 62 to 63°C, well below throttling limits.
Enhanced Performance during Heavy Loads:The Active Cooler proves particularly beneficial during heavy continuous loads, such as rebuilding the Linux kernel, where thermal throttling can occur. It helps maintain a maximum temperature under load that is significantly below the 80 and 85°C throttling thresholds.
Flexible Cooling Options:The Active Cooler can be used independently with a passive heatsink or integrated into a fan case. This flexibility allows users to choose between different cooling configurations based on their specific needs and preferences.
Optional Cooling for Improved Performance:While the Raspberry Pi 5 is designed to handle typical client workloads without active cooling, the Active Cooler offers an optional solution for users looking to enhance performance, especially under heavy continuous loads. It ensures that the Raspberry Pi 5 operates optimally, minimizing the impact of thermal throttling.
No Mandatory Cooling Requirement:It's important to note that while the Active Cooler provides significant benefits in terms of temperature management and performance, cooling of any type, including passive cooling, is not mandatory. The Raspberry Pi 5 can still operate safely without active cooling, and no harm will come to the device if left uncooled.
