The OS is not involved in over-temp shutdown logic. It happens at the
ACPI level. The firmware lets the kernel know, so you can at least see a
message in your /var/log/messages to let you know that you hit the
thermal cutoff, but the logic to trigger the shutdown is in the
firmware, not in the OS. You should be able to tell
from /var/log/messages if you're hitting thermal cutoff, just look for a
message about critical temperature threshold exceeded (or something
roughly like that) around the time of the shutdown.
