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.
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.
