Raspberry Pi Compute Module 4 (CM4) Cooler Comparison
Comparing 2 cooling configurations for the Raspberry Pi Compute Module 4 (CM4). SoC: Broadcom BCM2711.
Thermal Analysis
We tested 2 cooling configurations on the Raspberry Pi Compute Module 4 (CM4), built around the Broadcom BCM2711, each with an identical 60 minute sustained CPU stress workload. With no cooling fitted, the board idles at 36°C and peaks at 76°C under load and completes the full test without thermal throttling.
The strongest result came from the EDATEC ED-CM4COOLER (passive cooling), which cut the peak load temperature by 21.0°C to 55°C at a price of $4.60.
Across all configurations, peak temperatures ranged from 55°C to 76°C, a spread of 21°C. 1 of 1 aftermarket cooler completed the test without any thermal throttling. The Raspberry Pi Compute Module 4 (CM4) can run without extra cooling, but even a basic heatsink lowers operating temperatures and helps long term reliability.
