Rock64's temperature while being in aluminium case

[rasputin]

Hello,

I am about to order from pine64 website these : 1 Rock64 4GB, 1 EU power supply, 1 heatsink and 1 "Model B" premium aluminium casing.

I wonder how the Rock64 is doing while being locked up that aluminium case as I don't see any openings. Is this casing effective at keeping the Rock64 cool (or not too warm ^^) ?

Anyone to shut my concerns down ?

Thanks a lot

Hi _zernok, hi forum!

I recently purchased a Rock64 (4GB version) and a "Modell B" Premium Aluminium Casing. I successfully installed DietPi (downloaded from https://dietpi.com/) on a 16GB eMMC. Unfortunately, the SBC crashes occasionally with a kernel panic.

I assume the cause is a thermal problem. I used the tool stress and could reproduce the failure. With low load, the Rock64 runs stable for days.

I tried to catch the kernel panic message, but I have currently no sufficient UART level converter at hand that is fast enough for the 3 Mbaud serial console of the Rock64 (only a CP2102-based one). This way, I hope to get some information which point to the root cause of the kernel panic.

The cover of the casing features a "L"-shaped "heatpipe" inside that attaches to the SOC and memory chip of the Rock64 via a thermal compound. Hence, there is no simple way to attach an additional heat sink to the Rock64 inside the casing.

Does anyone have/had the same problem and an idea how to fix this?

Thank you in advance!
