Lm-sensors

lm_sensors is a tool/driver for monitoring CPU/Motherboard temperature, fan speeds, voltage information, etc.

Warning
'''Installing (not only running) lm_sensors can cause your computer to spontaneously switch off days later. See lm sensors problems.'''

 * Have the package lm_sensors installed as described under installing software.
 * Set it up
 * Test it like this

coretemp-isa-0000 Adapter: ISA adapter Core 0:     +61°C  (high =  +100°C)

coretemp-isa-0001 Adapter: ISA adapter Core 1:     +60°C  (high =  +100°C)

coretemp-isa-0002 Adapter: ISA adapter Core 2:     +57°C  (high =  +100°C)

coretemp-isa-0003 Adapter: ISA adapter Core 3:     +54°C  (high =  +100°C)

You can now use your sensors with the program ksensors.
