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.

Nothing:

While things are running hot, that might not be a problem. A number of files
are truncated.  For example:
/usr/libexec/gcc/x86_64-redhat-linux/4.7.2/

I may need to re-install.  Is there a way to clone my F17 installation
before I run fedup?  It would be nice to have a fedup mode that installs
to a new partition, based on settings and packages in the currently
running one.  Given existing F18 problems, I'm a bit nervous about running
fedup in place and thus risking my working F17 installation.  I guess
I could back up my disk with clonezilla (for example), but that's a pain.
