What is a CPU and CPU fan?

A Central Processing Unit (CPU) is the main microchip in a computer, while a CPU fan is the dedicated fan that helps keep the processor cool. A CPU fan works in conjunction with a heat sink to prevent this. CPU fans often work together with heat sinks to keep a computer cool.

What is the function of CPU fan and heatsink?

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). As the name suggests, it is composed of a passive cooling unit (the heat sink) and a fan.

What does CPU fan mean?

[¦sē¦pē¦yü ′fan] (computer science) A fan mounted directly over the integrated-circuit chip containing a computer’s central processing unit to prevent overheating.

Is a heatsink the same as a fan?

The heatsink draws the heat away from the CPU, and the fan ensures a steady stream of air for the heatsink to pass the heat to. However, there is more to selecting a heatsink and fan than just looking for a good price or one that looks cool.

What is heatsink CPU?

A heatsink is a piece of metal that sits on top of a computer chip such as a CPU and draws power away from components by letting it rise through a set of fins. Heatsinks leverage a thermal conductor to move the heat into fins, which have larger surface areas and thus disperse the heat throughout the computer.

How do CPU fans work?

Convection. The basic thermodynamic principle behind CPU cooling is convection. A hot object transfers some of that heat to the air molecules near its surface, cooling slightly in the process. If the air is moving, then these heated molecules will float away, allowing cooler air to replace them and absorb more heat.

How does a heatsink fan work?

Heatsinks work by absorbing heat from the CPU or GPU to which they are attached. As the CPU or GPU warms up, heat will transfer to these fins where it’s released using a fan. A fan is attached over the heatsink to circulate air. The fan runs in reverse, meaning it draws the hot air away from the CPU or GPU.

Can you use a CPU fan as a case fan?

Yes you can use it as a case fan. Just plug the black yellow green wires in. (The blue will hang over the fan header.)

Is a heatsink a CPU cooler?

A heatsink is a component in CPU cooling. The heatsink is the aluminum piece that sits beneath the CPU fan. A CPU Cooler is more commonly an aftermarket variation. If you buy a boxed CPU, it comes with a heatsink and fan.

How do heatsink fans work?

What is a CPU heatsink?

Does a computer CPU need a heatsink?

The main chip or computer processing unit ( CPU) requires a heatsink , and chipsets also use heatsinks . The size and design of these devices varies, as do materials and method of attachment.

Does a CPU really need a fan?

While there are people who can manage a modern CPU without a fan, it’s more or less true that any modern CPU requires a fan. It’s just lucky that these days a CPU whose fan stops will throttle then shut down, not burn.

Do processors come with a heatsink/fan?

Retail processors generally come with a heatsink/fan. Yes. They also sometimes come with a pre-applied thermal pad, in which case you wouldn’t necessarily have to apply thermal grease (though it’s generally better to use good thermal paste instead of a thermal pad.)
