That was actually exactly what THG was attempting to illustrate ... the
ineffectiveness of the (then) current generation of Athlon boards to
properly shut down in the case of cataclysmic failure of the CPU cooler
(i.e. if it fell off ... which has happened) The article was written
September 17, 2001

However, after discovering this problem and notifying AMD great efforts were
made to prevent this ... and hence newer generation of motherboards have
been updated to handle such situations. A follow up article was posted on
October 29, 2001 outlining THG's talks with AMD and the updated standards
for thermal protection required by AMD for new boards.

"Thermal Death" is now not a problem with new Athlon boards, nor many made
after AMD updated their standards for thermal overload.
Hope this helps clarify a bit.
