If you are not keen on installing and configuring Conky to your desktop, there is another wonderful tool to keep tabs on the health of your computer. It’s called Psensor
Head to your Software Manager and do a search for psensor. After you get it installed, launch it from your Menu, and do a very quick configuration of what sensors you want to show, and what colors you want them to display and off you go!
Psensor will monitor all the temperature probes in your machine, as well as fan speeds. It’s nice to keep an eye on your processor temperature when under heavy load.
You can also log everything to a file for future viewing, and my favorite part, by installing the psensor-server, you can monitor your remote servers health just as easy.
