Icy Box Enclosure IB-RP111

[ghrimx]

CPU cooling test with the enclosure from Icy Box IB-RP111

Full aluminium case with 2 massive aluminium heat sinks on CPU and IC.
The 2 heat sinks bridge the CPU and the IC to the top of the aluminium case allowing the heat to dissipate outside.

Test:

Test performed with RPi4B 8Gb running Raspbian GNU/Linux 11 (bullseye).
External temperature: 24°C
Run: 5 min idle then 30 min max CPU
Config A: stock clock
Config B: over_voltage=4, arm_freq=2000, gpu_freq=600

Results:

Conclusion:

Very effective case but the thermal pads are thicker than most pads that we can find. I think that replacing the pads each time access to the GPIO is needed will make the design frustrating in the long run.
