Fan always on Ubuntu 13.10

That's annoying...I know.
After a fresh install of Ubuntu on their laptop some people are having overheating issues, fan always on and consequently short battery life.

There's an extremely easy solution for that.
Install TLP, a tool that will take care of your laptop's life.

Open the terminal (Ctrl + Alt + T) and type the following commands:

sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install tlp tlp-rdw
sudo tlp start
