I would check out google on the issue as suggested, also look through 
CRON for all users to verify that nothing strange is in there, or 
something isn't tripping it off. At the very least it may be something 
different than core temps, since some systems have memory temp ability, 
as well as on-die versus on chip temp monitoring. From all you have 
said, I would focus more on CRON and validate that what you have 
installed on the system isn't doing something silly.

On the other hand, it could just be missing its dust blanket ;)
