Heat on Hummingboard

[Hannes Worst]

Recently I took my old Hummingboard and to run Armbian on it. I chose the desktop-version for Hummingboard using mainline kernel (presently 4.11.6-cubox). Unfortunately Armbianmonitor shows high CPU -temperature. It gradualy builds up, starting from 50 degrees next to 70 degrees, eventualy approaching 85 degrees and then it shuts down. I use the passive heatsink that came with the board and no case. I use it for light desktop things like browsing the internet.

Is there something I can do to prevent this, is there something in the kernel like throttling when the board reaches a certain temperature?

Thanks again for a great OS, I think you are doing an outstanding job for all those different kinds of boards!

[Igor]

That's unusual. Haven't notice any troubles on last testing, but it's true that I didn't test with HB1 but only with HB2 ... can you provide logs (armbianmonitor -u) and information - is there any activity on the board? Exactly which board do you have? Is board in some case, perhaps heat sink got detached somehow?

 

Thanks for compliments

Armbian monitor gives me at the moment this output:

[Igor]

This is more or less maximal temperature (from internal and external sensor) that I could get while running full desktop with browser and this:

stress --cpu 8 --io 4 --vm 2 --vm-bytes 128M --timeout 200

Current ambient temperature is around 20°C

I'll upgrade to latest and do tests again.

Edit: no changes after apt update and upgrade to 4.11.6-cubox 

[Hannes Worst]

That keeps me puzzeled. I use exactly the same image on more or less the same machine, only single core. The logs are absoluty comparable. Maybe I have a faulty board, or it has something to with Midori. Midori is known to spike the CPU at moments. Thanks for the detailed logs! I will go on to investigate ..

[Igor]

I also have single core with 512Mb memory, but it's Hummingboard 2 and it performs the same - up to 53°C It should use the same DT as yours. Check: http://sprunge.us/IGeF 

 

It must be related to SOM / u-boot settings?

[Hannes Worst]

In the meanwhile I think I found the source of the problem. A change of hdmi2vga adapter did the trick. The faulty adapter contained some kind of soundcard that triggered the CPU. Sorry for the disturbance!
