If your fan is running all the time, that means that your BIOS believes 
that your fan should be running all the time. For a number of reasons, 
Linux tends to generate more heat on most hardware than Windows does - 
that will tend to manifest itself as the fan being on more. In some 
cases there are ways that you can override the BIOS, but that's likely 
to lead to your machine running hotter than it was designed to.
