laurentppol Posted August 9, 2020 Author Posted August 9, 2020 GREAT, thats what I may use in script :). As one of my OPiPC+ repeatedly hangs, despite heatsinks, but it is in plastic enclosure, so I may suspect overheating. Now I will add not only date/time but temperature too to a "logfile". Changed uSD card from Toshiba to Samsung (A1) same. System is not the "old upgraded one" with whitch I had problems, but a clone of working OPi. Last thing is power, but there is SMPS 5V 3A + UltraCap 1F/5.5V, but who knows, cable is short (10-15cm) but poor quality (more than 1ohm @ 1m). But a bit strange, other one, w/o heatisinks, shows temp 74950 (I guess it is miliK) but runs (for now) for 8 days w/o problem.

That's 75C, check htop for speed, because it should be throttling down to 1.30Ghz until ~72C And high temp is not recommended longterm, try cpu max 1.1GHz Edited August 9, 2020 by xwiggen
laurentppol Posted August 9, 2020 Author Posted August 9, 2020 I will install a fan in the case this week (already got it from China). Then log temp/date and see if it hangs. I observed, that while hung, if I do a power cycle, temperature after boot is even 85*C. Then it (slowly) falls to 65-70*C. But I get temp about 70-75* in OPi3 in metal case, 4 heatsinks (1 "fake" -> a small metal tab on flash, but there is mPCIe connector) and fan. And it works rock-stable. I am curious, what will it be with OPi4 i plan to buy.

laurentppol Posted August 10, 2020 Author Posted August 10, 2020 Most suspect is OpenHAB2 (Java), seems too heavy for OPiPC+. But looks ok on OPi3 (even together with motion).

But this is while OpenHAB2 starting. But at then last moment it worked it had only ~53.5*C. What (how) to trace now? Replace SMPS (12V->5V 3A) powering device (& cable)? Remove case (temporairly)? Any ideas else?

Any ideas else? Load at bootup is <=1.82 (<50% all core utilization), 25C increase within minute seems very unlikely, what is likely (commit=600 in /etc/fstab) your monitoring script did not sync till the end, i.e. last temps are probably not logged to block device.
laurentppol Posted August 18, 2020 Author Posted August 18, 2020 Ok, yesterday installed fan (sold on Ali as for "Raspberry Pi 3" but it fits even inside casing), temperature (no real load) even below 40*C. (@ 26*C ambient). Will look that is to be going on. "1 liner" to log temperature@date-time launched, so there will be possibility to make a graph of this.
