Lm-sensors

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

How to set it up

Warning

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

Quick Recipe

• Have the package lm_sensors installed as described under installing software.
• Set it up

sensors-detect
sensors -s
/etc/init.d/lm_sensors restart

• Test it like this

Using it

You can now use your sensors with the program ksensors.

Frontends

There are many front-ends for lm sensors:
