I started using Ubuntu 32 bit last week. I love it but I recognized there was a problem with the cooling system. the fan doesn't stop and slightly loud all the time (that wasn't the case while running with windows 7). I told a friend who claimed that it should be a drivers problem. My machine is dell inspiron n5110 and the official site recommends win 7 64 bit only. there's no support for linux. (the page showing the machine drivers and system recommendation I tried to fix the problem using the "additional drivers", it opens but it shows nothing (no drivers to activate, just the help and the close buttons) is there a way to fix this?

Maybe your CPU is running on maximum performance all the time and generating a lot of heat, hence the fan doesn't stop. I suggest you to install Jupiter, as it will show your CPU temperature and also let you choose which performance profile you want. Here's how you install and configure Jupiter in Ubuntu 12.04.

Try installing i8kutils, and check out the information in this post How to control fan speed in Dell Inspiron 5010 (15R)?
