I noticed the CM5 thermal throttles pretty quickly without a heatsink. But is a heatsink enough? Or should you consider an Active Cooler instead? Check out my main channel Pi CM5 video: https://www.youtube.com/watch?v=X4blR5Ua3S0 And my video on the CM5 Development Kit: https://www.youtube.com/watch?v=pu5PlXzqRLI EDAtec sent me the Active Cooler I tested in this video for review, and Raspberry Pi sent the CM5 Heatsink I tested. They did not pay for this video, nor have any say in its contents. Here are the coolers I tested in this video: - Aluminum Heatsink for CM4: https://amzn.to/4i0Pfd7 - Raspberry Pi Heatsink: https://www.raspberrypi.com/products/heatsink/ - EDAtec CM5 Active Cooler: https://www.digikey.com/en/products/detail/edatec/ED-CM5ACOOLER/25696857?s=N4IgTCBcDaIKIBEC0BhAsgVgIIoPK4Bk4AlEAXQF8g Support me on Patreon: https://www.patreon.com/geerlingguy Sponsor me on GitHub: https://github.com/sponsors/geerlingguy Merch: https://www.redshirtjeff.com Main Channel: https://www.youtube.com/@JeffGeerling 2nd Channel: https://www.youtube.com/@GeerlingEngineering
