The Role of a Laptop Fan. How Does A Laptop Fan Work
The fan in a laptop is responsible for cooling the internal components of the device. The central processing unit (CPU) and graphics processing unit (GPU) generate a lot of heat when running intensive tasks such as gaming, video editing, or running complex software.
The heat produced by these components can damage the device if it is not dissipated. The fan in a laptop is designed to draw cool air from outside and push it through the internal components to remove the heat.
How Does a Laptop Fan Work?
The fan in a laptop works in conjunction with the heat sink. The heat sink is a metal plate that is in contact with the CPU and GPU. When the components generate heat, the heat is transferred to the heat sink. The fan then draws cool air into the laptop and pushes it through the heat sink, which dissipates the heat into the air.
The fan speed is controlled by the laptop’s motherboard. When the CPU and GPU are under load, the motherboard will increase the fan speed to help dissipate the heat. Similarly, when the device is idle, the fan speed will decrease to conserve battery life and reduce noise.
Different Types of Internal Fans Found in Laptops.
There are two main types of internal fans found in laptops: axial fans and centrifugal fans.
1. Axial fans: these are the most common type of internal fan found in laptops. They work by sucking in the air parallel to the fan’s axis and pushing it out perpendicular to the fan’s axis. Axial fans are simple, efficient, and cost-effective.
2. Centrifugal fans: on the other hand, are less common in laptops. They work by sucking in air perpendicular to the fan’s axis and pushing it out perpendicular to the fan’s axis. Centrifugal fans are more complex and expensive than axial fans, but they can move more air with less noise.
