Processor throttling

Alternatively referred to as frequency scaling, processor throttling is a feature that allows a computer's CPU to lower its frequency for a time, in order to prevent overheating or to save power. For example, if the processor has been doing a lot of work and is getting too hot, lowering the frequency will help to keep the processor from overheating. Lowering the frequency during idle times (when the computer is not being used) helps to conserve power, which is quite useful when dealing with laptops or other portable computers.
