I'm new to ubuntu and so far I've not had great experiences. Since I installed Ubuntu 12.04 LTS on my computer it seems like it's running hotter. What I mean by that is my fan is constantly on and running loud, even when idle at the desktop with no programs opened, even straight from boot and several hours after boot. I opened terminal and did the TOP thing and I wasn't running any CPU power and i was using like 0.2 RAM.
I had 12.10 at first but figured since there is a LTS group for 12.04 I'd give it a try and the problem remained.. this problem never existed when I previously ran Windows 7. I even went as far as to take apart my laptop and blow it out and clean the fan, ect.
I was told there is a certain problem with ubuntu running right off the graphics card and that there is a fix for it, to make it run cooler. I have yet to find this fix so any helpful advice on the matter would be awesome.
