We can simply do this by installing "Xsensors":

http://apt.ubuntu.com/p/xsensors

This application will install "lm-sensors". If the addon is not selected there, you need to select it.

After you install xsensors, you need to configure lm-sensors.

To do so, open Terminal and run:

 sudo sensors-detect

just press ENTER for everything it suggests. Lastly it will show whether to add what it finds to /etc/modules. Hit Enter again and you are done.

Now open Dash and search for xsensors.
