For watching the CPU temperature you've got coretemp(4) for Intel CPUs and
amdtemp(4) for AMD CPUs. Both report their values through sysctl(8), and both
can be loaded as modules. N.B: they're not built into the GENERIC kernel.
Just kldload the appropriate module and then do `sysctl -a|grep temperature`.

If you have an ASUSTeK motherboard, the aibs(4) driver gives information about
temperatures, voltages and fan speed.

You can use smartctl from the sysutils/smartmontools package to monitor the
health of harddisks. The disk temperature is given as the attribute name
“Temperature_Celsius” when you run `smartctl -a /dev/<disk>`.

E.g. the sysutils/conky port can be used as a system monitor.
