This machine has a case fan at the end of a plastic tunnel that draws air 
past the CPU package slots.  It doesn't have a heat-sink fan.

"Reliable" in the sense that it was not intermittent.  My BIOS has a 
setting that will force power off when thermal violations are detected. 
That's what was doing the shutdown.

Linux may make your CPU work hard, but it shouldn't cause it to overheat 
if the hardware is otherwise OK.  See the other posts in this thread.
