LS1043ARDB: critical temperature reached (85 C) issue

I have two LS1043ARDB-PD boards with LKSDK-20.12 Linux version 5.4.47.

I am facing a high temperature issue on these boards. (even when no external device is connected)

thermal thermal_zone1: critical temperature reached shutting down
thermal thermal_zone1: critical temperature reached (85 C), shutting down
thermal thermal_zone1: critical temperature reached (85 C), shutting down

The board boots up with 52C and then it keeps on increasing. It is mainly happening on /sys/class/thermal/thermal_zone1/temp.

What is reason behind the high temperature reading?

How do I fix this issue?

Please describe external conditions at which the overheating is registered.

Is the internal chassis fan operational?
