ITHERM(4)                BSD Kernel Interfaces Manual                ITHERM(4)

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

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.
