The itherm driver first appeared in OpenBSD 4.8.

The itherm driver was written by Mike Larkin <mlarkin@openbsd.org>.

Not all sensors are wired on every machine, so the list of sensors shown in sysctl(8) may not show all the sensors listed above. Furthermore, the itherm driver will flag sensors as invalid if they report bogus data.
