Cpu Heat Sink And Fan Definition

Stands for heat sink and fan nearly all computers have heat sinks which help keep the cpu cool and prevent it from overheating.

Cpu heat sink and fan definition.

There are two distinct types of convection. Cpu gpu asic fet etc and the surrounding fluid is air. But sometimes the heat sink itself can become too hot. 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.

Usually heat sinks are outfitted with built in fans to help keep both the cpu and the heat sink at an appropriate 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. The picture is an example of a heat sink that has both active and passive cooling mechanisms. 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.

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. As the name suggests it is composed of a passive cooling unit the heat sink and a fan. Cpu fans and heatsinks help ensure that your pc works efficiently at all times. 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.

The cpu fan attaches to the heat sink pulling air through the fins. Cpu fans often work together with heat sinks to keep a computer cool. 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. In computers heat sinks are used to cool cpus gpus and some chipsets and ram modules.

Laptops present a difficult mechanical airflow design power dissipation and cooling challenge. A cpu fan works in conjunction with a heat sink to prevent this. 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 many applications the device is an electronic component e g.

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.
