Since installing Ubuntu 12.04 on my Dell Inspiron Notebook that came pre-installed with Windows 8 (very unfortunately),
I have been experiencing an increase in the fan's loudness and frequency of running. I have the system load indicator installed, and any time there is a spike (even small spikes) in resource usage, my fan turns on very loudly and continues for about two to five minutes. This happens also sometimes without a spike in resource usage. It happens about every 10 to 20 minutes. As far as I can tell, the temperature of the computer never rises enough to warrant such activity.
I have looked around online and found some advice, but I didn't want to go in and start messing with things right away without someone giving sage advice for my particular problem and laptop. I am a brand new Ubuntu user, and immensely enjoy everything about it thus far, except for the dramatic change in my fan.
How can I fix these issues?
