How to Monitor Hardware Temperatures on Ubuntu 11.10/11.04

It's important to Keep a close eye on different hardware temperatures and voltages on Ubuntu 11.10/11.04. This will help you make sure your system isn't overheating.

To monitor, for example, CPU, GPU, HDD, motherboard temperature, or fan speed on Ubuntu, you may need the Hardware Sensors Indicator (Indicator-Sensors), which will bring your sensors outputs on your desktop. We will also see the Psensor temperature monitor.

To install  Indicator-Sensors on Ubuntu 11.04/11.10, run these commands from the terminal:

sudo add-apt-repository ppa:alexmurray/indicator-sensors
sudo apt-get update
sudo apt-get install indicator-sensors

You can then start the indicator via the Unity dash by searching "Hardware Sensors Indicator":

- Psensor is also another hardware temperature monitor for Linux. It allows via a GUI to monitor temperature of the motherboard, CPU, NVidia GPU, hard disks, fan speed, etc.  To install it on Ubuntu 11.10/11.04, run these commands from the terminal:

sudo apt-add-repository ppa:jfi/ppa
sudo apt-get update
sudo apt-get install psensor

That's it!
