The itherm driver provides support for
several sensors found in Intel 3400 and 5 series chipsets.
The sensors currently exposed via the sysctl(8) interface are:
| Sensor | Units | Typical Use |

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.
