I am running DELL Vostro 3750, operating system Linux Mint and despite all my attempts the fan is still running very fast and loud. So far I have tried first edit Grub according to this article. Than I tried to install nvidia drivers according to this manual but all got was a screen telling me that the X screen can't be started because no X devices were found. So I had to delete
/etc/X11/xorg.conf file. Before I had ubuntu 12.04 and the problems were the same. There I also tried Jupiter and the bumlebee project. But no results.
This is my computer's information:

EDIT: Ever since I asked this question I, time to time, tried to look for some complex solution to this problem. Eventually I hit on THIS absolutely perfect answer that helped me solve all my troubles with overheating and fan noise. Just follow the instructions and you will be fine. Especially I recommend using indicator-cpufreq.
