According to the acpidump, there is no _PSL control method, which is mandatory for a passive trip point.
So, this is a BIOS bug to me, and there is no way to fix it in Linux kernel.

Bug closed.

BTW, if you're running into a real overheating issue on this machine, I think you can set CONFIG_INT340X_THERMAL and use the int340x thermal drivers plus userspace thermal daemon for thermal control.

How do I know if I have this temperature problem? How do I check this?

you can attach the out of "grep . /sys/class/thermal/thermal*/*"

/sys/class/thermal/thermal*/temp shows the current temperature of each thermal zone.
