i installed ubuntu 13.10 on my dell inspiron 5520 and this is my first experience with ubuntu or any OS other than windows..

the system starts up normally and functions although it seemsto be slower than win 8.1 (thats not much of an issue though) but once the fan starts running it wont stop untill i shut down the laptop. this is the only major issue i have with ubuntu

Why 13.10 and not 14.04? – TuKsn May 29 '14 at 10:18

One thing I would check would be the load of the system (as this is usually the case when the fan revs up), fire up a terminal and type:


To read more about the load values, see for example this thread:

If it seems high, you might also wanna dig deeper into the top command:


and even checking all the process, with

ps -aux 

trying to pinpoint if there are applications running hot.
