No Pi-Touch (i just tried with HDMI), both raspberry are 3B+, with Hifiberry DAC RTC+, ethernet, and SDCARD class 10.
I tried 4.19.42 and 4.19.34 kernel with 5.2, but no differences. I don't know if the difference i saw on the CPU usage between 4.4 and 5.2, has an impact on temperature (i guess yes a bit, but i didn't have time to test more).
EDIT: With a third RPI on 5.2 i can see kinda the same behavior as i saw in V4.4 earlier, so probably not relevant.
EDIT 2: No throttling (throttled=0x0)
