If I understand you correctly, 30 seconds is certainly enough time to burn
a CPU when the fan has failed, isn't it?
Our old default poll interval was 30 seconds so this doesn't change
anything.  I know DeadRat takes more than 30 seconds from "shutdown -h
now" to power off.  All modern CPUs have a thermal shutdown builtin.
Think of _CRT as more of "system temp too high, shut down as soon as you
can."
