Cpu Heat Sink And Fan Definition

The picture is an example of a heat sink that has both active and passive cooling mechanisms.

Cpu heat sink and fan definition.

It may also shorten the life of your cpu or cause immediate damage. A laptop computer s cpu and gpu heatsinks and copper heat pipes transferring heat to an exhaust fan expelling hot air the heat is expelled from a laptop by an exhaust centrifugal fan. Cpu fans and heatsinks help ensure that your pc works efficiently at all times. But sometimes the heat sink itself can become too hot.

Laptops present a difficult mechanical airflow design power dissipation and cooling challenge. Cpu gpu asic fet etc and the surrounding fluid is air. In many applications the device is an electronic component e g. As the name suggests it is composed of a passive cooling unit the heat sink and a fan.

When you use heavy applications such as video games and video editing software the cpu can produce excess heat which may cause your computer to freeze. A heat sink is a metallic device that sits directly on the cpu drawing heat away from the chip into its cooler aluminum fin like structure. Usually heat sinks are outfitted with built in fans to help keep both the cpu and the heat sink at an appropriate temperature. Cpu fans often work together with heat sinks to keep a computer cool.

There are two distinct types of convection. A heat sink also commonly spelled heatsink is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium often air or a liquid coolant where it is dissipated away from the device thereby allowing regulation of the device s temperature. This can happen if the cpu is running at full capacity for an extended period of time or if the air surrounding the computer is simply too hot. A heat sink is a device that incorporates a fan or another mechanism to reduce the temperature of a hardware component e g processor there are two heat sink types.

A heat sink and fan hsf is an active cooling solution used to cool down integrated circuits in computer systems commonly the central processing unit cpu. In computers heat sinks are used to cool cpus gpus and some chipsets and ram modules. The cpu fan attaches to the heat sink pulling air through the fins. The device transfers heat to the heatsink by conduction the primary mechanism of heat transfer from the heatsink is convection although radiation also has a minor influence.

Basically what a computer fan do is pull the heat from the heatsink that is connectted to the cpu and escorts it out of the computer because if the cpu gets to hot then the computer just stop.
