Thanks for your tip on envstat! I wouldn't have known about that. I can't
find anything like that in FreeBSD.
I ran envstat on the computer I am using now, and later tried on the
overheating computer.
On the overheating computer, I booted a NetBSD installation single-user,
immediately ran envstat several times.
CPU temperature went from 97 C to 98 C, and there was a warning console message
about the CPU being critically hot.
I then ran "shutdown -p now".
Reason for booting single-user was to make the root filesystem read-only. That
way, if the power cut off, and I couldn't unmount cleanly, the root filesystem
would remain unchanged.
It seems to me the CPU temoerature would drop to near room temperature when the
power is off. So I suspect either an error in the CPU or motherboard
temperature sensor, or the heatsink could be clogged or otherwise
nonoperational.
Replacing the heatsink and fan is the logical next step, and the replacement
Arctic cooler is already ordered and in transit.
