— Intel
Core on-die digital thermal sensor
coretemp* at cpu?
The coretemp
driver provides support for
the on-die digital thermal sensor present on Intel Core and newer CPUs.
The temperatures can be observed by using the envsys(4) API or the envstat(8) command. Temperatures are reported for each core separately.
The coretemp
driver is able to send a
critical
event to the powerd(8)
daemon. The script
/etc/powerd/scripts/sensor_temperature will be
executed by the daemon (if running) when the limit has been reached.

The coretemp
driver was written by
Rui Paulo

as part of a Google Summer of Code project. It was adapted to
