I have perfectly equal Orange Pi Zero Plus 2 H3 boards in their original case - booting from eMMC.
Test conditions are: WiFi Hotspot enabled, HDMI off, CPU idle, CPU governor: performance, CPU freq. 240MHz - 1.1 GHz, kernel 4.14.84
Xiaomi Mi5 Charger as psu, 2.4A usb cable
armbianmonitor gives me a temp of ~50°C on one board (idle@1.1GHz)
and a temp of 65°C on the other board (same conditions, CPU starts throttling here to ~960 MHz).
The temp gets so high, that after an apt-get update/upgrade and reboot the opizero plus2 would not boot with an error msg that the temp is too high.
The temp seems to be correct more or less, since also the power consumption is significantly higher. While the 50°C board draws ~1.5W, the 65°C board draws ~1.8W.

I have no explanation for this...
