Processor throttling
Updated: 04/26/2017 by Computer Hope
Alternatively called frequency scaling, processor throttling allows a computer's CPU (central processing unit) to lower its frequency for a time, prevent overheating, or save power.
Preventing a processor from overheating can prevent damage to the processor. Lowering the frequency during idle times (when the computer is not being used) helps conserve power, which is quite useful when dealing with laptops or other portable computers.
