Combination

Host Raspberry Pi Raspberry Pi Compute Module 5
Other DeskPi Super4c

Symptom

Overheating / throttlingSlower than expected

Notes

The DeskPi Super4c ran four Compute Module 5 nodes in an HPL benchmark. With only the passive heatsinks the modules throttled quickly; a 5V 120mm fan placed on top of the heatsinks was needed. (from GitHub issue #814)
