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 $5.95.
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.

Frequently Asked Questions
How hot does the Raspberry Pi Compute Module 4 (CM4) get without a cooler?
The Raspberry Pi Compute Module 4 (CM4) reaches 76°C under sustained CPU load without a cooler, with an idle temperature of 36°C. No thermal throttling was observed.
What is the best cooler for the Raspberry Pi Compute Module 4 (CM4)?
The EDATEC ED-CM4COOLER provides the best thermal performance, reducing load temperatures by 21.0°C to a peak of 55°C at a price of $5.95.
Does the Raspberry Pi Compute Module 4 (CM4) need a cooler?
The Raspberry Pi Compute Module 4 (CM4) does not thermally throttle under sustained load even without an aftermarket cooler. However, a cooler will still reduce operating temperatures, which can improve long-term reliability.
