What is CPU Heatsink?

 I believe everyone knows the CPU, which is the core processing element of every PC and is responsible for processing every data on the computer. CPU Heatsink manufacturer Coolsolte will share with you what is CPU Heatsink through this article, let's take a look.

 

What is a CPU Heatsink?

A heatsink is a piece of metal (usually aluminum or copper) made up of multiple heatsinks, placed on top of the CPU with a fan or liquid cooler to transfer heat and help cool the CPU.

 

Why do CPU need a CPU Heatsink?

A CPU can quickly overheat because some of its components generate heat. Without a heat sink, the heat generated by the components can remain in the CPU, causing it to overheat or even burn up. Because most components are made of electronic chips, they can easily absorb heat. If they receive too much heat, they can be damaged and affect the proper functioning of the PC for use.

 

The cooler is the best solution to help solve CPU overheating. CPU coolers can dissipate heat from the CPU while it is working because they have multiple heatsinks, so they can provide a larger surface area during heat transfer and maintain effective heat dissipation even when the CPU is working for a long time.

 

How do heat sinks work?

The workings of a heat sink can be divided into four basic steps.

1. Heat source: This can be any system that generates heat and needs to remove said heat to function accordingly, such as mechanical, electrical, chemical, nuclear, solar, and friction.

2. Heat transfer away from the source: In applications in direct contact with the heat sink, heat enters the heat sink by natural conduction and moves away from the source. The thermal conductivity of the heat sink material directly affects this process. This is why highly thermally conductive materials like copper and aluminum are so common in the construction of radiators.

3. Heat is distributed throughout the radiator: Heat will be naturally conducted through the radiator by natural conduction through a thermal gradient from a high-temperature environment to a low-temperature environment. This ultimately means that the heat distribution of the radiator will be inconsistent. As a result, the radiator will typically be hotter near the heat source and cooler at the end of the radiator.

4. Heat moving away from the radiator: This process depends on the temperature gradient of the radiator and its working fluid (i.e., fan or liquid cold plate).
