A couple of things to check:
- are all fans running?
- is the case dust clogged?
- is the CPU pegged at 100% for long periods?

If all of the fans are operational, check for buildup of dust.  A can of
air and a face mask (if you're allergic) will clean the system quickly
and efficiently.  Be careful to clean only when the system is off.

If a CPU fan is not running, shut down the system immediately and fix
it.  If a case fan is not running, it's probably OK to leave the system
open until you can replace the fan.

The message indicates a serious problem that you need to address as soon
as possible.  Running too hot can do serious damage.
