Nn a Dell Inspiron the CPU Fan is too loud. It is not running constantly, but it changes from slow to really fast every minute. It's really annoying and hardly possible to work on this machine.
Is it possible to limit the range the fan is using?

There are no pwm-capable sensor modules installed
Install lm-sensors and try again. You can install lm-sensors with software center or in a bash terminal:
Next try installing and using the i8kutils "Utilities for Dell Inspiron and Latitude laptops"
