+.Sh NAME
+.Nm itherm
+.Nd Intel 3400 Thermal Sensor
+.Sh SYNOPSIS
+.Cd "itherm* at pci?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for several sensors found in Intel 3400 and 5 series
+chipsets.
+.Pp
+The sensors currently exposed via the
+.Xr sysctl 8
+interface are:
+.Bl -column "Sensor          " "Units" "Typical" -offset indent
+.It Sy "Sensor" Ta Sy "Units" Ta Sy "Typical Use"

+.It Li "Core 1" Ta "degC" Ta "Temperature"
+.It Li "Core 2" Ta "degC" Ta "Temperature"
+.It Li "CPU power cons." Ta "Watts" Ta "Power usage"
+.It Li "CPU/GPU Max" Ta "degC" Ta "Temperature"

+.Xr pci 4 ,
+.Xr sensorsd 8 ,
+.Xr sysctl 8
+.Sh HISTORY
+The
+.Nm
+driver first appeared in
+.Ox 4.8 .
+.Sh AUTHORS
+The
+.Nm
+driver was written by
+.An Mike Larkin Aq mlarkin@openbsd.org .
+.Sh CAVEATS
+Not all sensors are wired on every machine, so the list of
+sensors shown in 
+.Xr sysctl 8
+may not show all the sensors listed above.
+Further, the
+.Nm
+driver will flag sensors as invalid if they report bogus data.
