Check out healthd or mbmon. One or other has worked OK for me on other
Asus boards, and both are in ports (sysutils/ I think).
If you have ACPI and your board supports thermal zones, then you can
check those.
sysctl -a | egrep 'acpi.*therm'
or
sysctl -a | egrep 'acpi.*tz'
one or other should be a good enough incantation. None of my ASUS mobos
do have thermal zones so I can't be sure -- it's much more commonly
supported in laptops.
Or just
sysctl -a | egrep acpi
and eyeball for anything that looks like temp information.
Also beware of constant monitoring. Every now and again (once a day on
average), I find mbmon sits chewing CPU and pushing the temperature up
itself. So I run in with
(ulimit -t 1; /usr/local/bin/mbmon -p winbond -c 1)
which means that the parent shell kills it if it uses more than 1 second
of CPU, which is far more than it needs.

PS Many disks which support SMART can display their apparent temp as one
of the SMART parameters (see sysutils/smartmontools). Not 100%
trustworthy, but better than nowt. I'd rather fry the processor than a
disk :-)
