I have been monitoring temperature on my DC-board several times pr. day for some days now and it suddenly raised from 26-ish to 42,9°C. No change in room temperature. What kind of temperatures can I expect during normal operations?
Its hard to say what is normal since the enclosure will make a huge difference, but the data sheet for the processor says that the max temp is 85C… after that I would think it will get unstable or be damaged.
This doesn’t mean other components dont have a lower threshold that will cause issues, but the processor is usually the thing that will cause a problem.
Out of curiosity, how are you checking the temp?
Thanks for the info! My DC is not in an enclosure yet.
SSH to the DC
mine looks like this, no enclosure, and about 20°C room temp:
once your temp reading “jumps up” try to measure the SoC with a multimeter temp head so you can double check if there is some SW bug fooling you or the temperature truly jumped up. Just an idea. I having a cheap multimeter with NTC probe, or there are some IR remote sensing probes too not sure if you have some of those. (I guess the ‘thermal_zone0’ shows the core temperature, and we can measure only the package temperature on the SoC so there should be an offset)
Ahh ok just making sure there wasn’t another way i didnt know about…
