'''Dynamic frequency scaling''' (also known as '''CPU throttling''') is a [[power management]] technique in [[computer architecture]] whereby the [[Clock rate|frequency]] of a microprocessor can be automatically adjusted "on the fly" depending on the actual needs, to [[Power management integrated circuit|conserve power]] and reduce the amount of heat generated by the chip. Dynamic frequency scaling helps preserve battery on mobile devices and decrease cooling cost and noise on [[Quiet PC|quiet computing settings]], or can be useful as a security measure for overheated systems (e.g. after poor [[overclocking]]).
