I am using a Dell Inspiron 15R 5520 laptop running Ubuntu 14.04 with kernel version 3.13.0-34 generic. Since installing the OS, I have been having issues with my computer's fan spinning at its maximum speed for prolonged periods of time. I tried installing TLP, which works sometimes, and I also tried i8kutils but it only turned my fans off. This fan issue occurs more frequently when on AC power, and I cleared the exhaust of dust already.
Why is this happening?
I am not an advanced Linux user, but I am open to any suggestions you have at this point. Listening to a fan running at max is annoying.
