 How can't it be critical?  Your system is overheating.  It is about to
fail -- depending on the configuration, it'll either crash or be shut down
by hardware (consider fire in the server room as well).  Either way the
condition should be caught ASAP, for proper steps to be taken by the OS
and/or the operator.  Otherwise it might have no second chance to get
reported and the system will die silently -- you'll not know the reason
until you get at the console (or its remains).  It may be too late then.
