# NAME

`itherm` — Intel 3400 temperature sensor

# SYNOPSIS

`itherm* at pci?`

# DESCRIPTION

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
`Thermometer` | degC | Temperature
`Core 1` | degC | Temperature
`Core 2` | degC | Temperature
`CPU power cons.` | Watts | Power usage
`CPU/GPU Max` | degC | Temperature
`DIMM 1` | degC | Temperature
`DIMM 2` | degC | Temperature
`DIMM 3` | degC | Temperature
`DIMM 4` | degC | Temperature
`GPU abs.` | degC | Temperature
`PCH abs.` | degC | Temperature

# SEE ALSO

pci(4), sensorsd(8), sysctl(8)

# HISTORY

The `itherm` driver first appeared in OpenBSD 4.8.

# AUTHORS

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

# CAVEATS

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.
