Cpu Heat Sink And Fan Definition

In many applications the device is an electronic component e g.

Cpu heat sink and fan definition.

As the name suggests it is composed of a passive cooling unit the heat sink and a fan. 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. In computers heat sinks are used to cool cpus gpus and some chipsets and ram modules. 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.

But sometimes the heat sink itself can become too hot. 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. Laptops present a difficult mechanical airflow design power dissipation and cooling challenge. There are two distinct types of convection.

Cpu fans often work together with heat sinks to keep a computer cool. 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. A heat sink is a thermal conductive metal device designed to absorb and disperse heat away from a high temperature object such as a computer processor. 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.

Stands for heat sink and fan nearly all computers have heat sinks which help keep the cpu cool and prevent it from overheating. It may also shorten the life of your cpu or cause immediate damage. 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. Cpu fans and heatsinks help ensure that your pc works efficiently at all times.

Cpu gpu asic fet etc and the surrounding fluid is air. 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. Usually heat sinks are outfitted with built in fans to help keep both the cpu and the heat sink at an appropriate temperature. The picture is an example of a heat sink that has both active and passive cooling mechanisms.

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.
