Try "sysctl hw.acpi.thermal"

For more information see "man acpi" and man "acpi_thermal". If you're 
lucky it gives you information on the ACPI thermal control system, if 
you have one.

If you want an alarm based on this, a shell script is easy enough.

If that doesn't do it for you, try some of the others. I've known these 
to work (sometimes)


And there are some fun modules you can add to loader.conf (stuff I've 
done in the past, but could be on an early version of FreeBSD)


Then give "sysctl dev.cpu | grep temperature" a try.

If you're worried about your Winchesters getting over-cooked you can use 
smartctl, available in /usr/ports/sysutils/smartmontools. Something like 
"smartctl -a /dev/ad?? | grep -i temp" should do the trick. It lets you 
mess with the drive SMART (self-diagnositc) system and it can tell you 
all sorts of stuff about you drive performance to make you really paranoid.
