Jetson Nano 2gb SBC thermal zone 4 temperature issue

[lawrence128]

I have a Jetson Nano 2gb SBC and I want to make sure that it is operating normally before I start learning A.I.
I found that the thermal_zone_4 temperature is constantly running at 100 degrees. The heat sink gets really hot after a few hours.
Is that normal?
If not, what should I do?

Maybe you can check if that thermal zone is always 100 even right after you boot up the device…

If so, maybe you are asking the same question as

PMIC temperatures of 100 degrees celsius

Good afternoon! The jtop and tegrastats programs show PMIC temperatures of 100 degrees celsius. What could be the problem?, really the chip warmed up?, and is that the problem? At the forum I found information, but it also showed a temperature of 100 degrees and jetson AGX had problems.
