Cool'n'Quiet

Cool'n'Quiet is a feature in some computer processors that helps them stay cooler and quieter. It works by reducing the speed of the processor's fan when the computer isn't being used very much. This means that when you're not doing anything on the computer, it won't make as much noise. It also stops the processor from getting too hot which can help it last longer.
