Computer Fan Function

The cpu is the computers most important chip.

Tower fan grey. Fan control is the management of the rotational speed of an electric fan. If this component reaches a pre set temperature the computer will shut down. The speed of a fan is measured in revolutions per minute or rpm and the higher the rpm rating the faster the fan spins.

Controlling the cpu fan speed in your pc or all the fans in fact is a way to give you more control over your windows 10 experience. However in many cases the higher the rpm rating the louder a fan may be. A fan is a hardware device that keeps the overall computer or a computer device cool by circulating air to or from the computer or component.

A typical desktop or notebook computer has a cpu cooler consisting of a metal heat sink and a fan. Computer fans are sometimes noisy and irritating but they perform the very important function of cooling the computer specifically the central processing unit. In computers various types of computer fans are used to provide adequate cooling and different fan control mechanisms balance their cooling capacities and noise they generate.

This is commonly accomplished by the motherboards having hardware monitoring circuitry which can be configured by the end user through bios or. In fact its often referred to as the brain. A user can even supplement this function with additional cooling components or connect a manual fan controller with knobs that set fans to different speeds.

Fan control is not always an automatic process. The picture is an example of a fan on a heat sink. A computers bios basic inputoutput system can control the speed of the built in fan system for the computer.

The heat sink moves heat away from the processor and the fan forces the heated air out of the computer through a vent.
