1. Excessive load on your computer

 Excessive load on your computer is one of the main reasons why your laptop fan feels noisy.

The processing load on a computer fluctuates depending on the applications and software that the user operates. In particular, when high-performance games, large-scale data processing, or multiple applications are run simultaneously, CPUs and GPUs consume large amounts of power to achieve high performance and generate large amounts of heat.

For example, this applies when playing games that make full use of 3D graphics, editing large-scale videos, or running software that performs complex numerical calculations. Under these conditions, the fan starts spinning at high speed to efficiently dissipate the generated heat to the outside, resulting in loud noise.

In this way, by understanding that excessive computer load is one of the main causes of laptop fan noise, and by making appropriate usage and settings, it is possible to reduce fan noise problems. is.

2.Dust and foreign matter inside

Accumulation of dust and foreign matter is one of the main reasons why your laptop fan may be noisy.

Fans are responsible for cooling the inside of a computer, but their efficiency decreases significantly when dust and foreign matter accumulate. When dust accumulates, the fan blades may not rotate smoothly and may cause abnormal noise. Dust also tends to accumulate heat, which requires the fan to run faster.

If you use your computer for a long time or in a particularly dusty place, dust and foreign matter will easily accumulate on it. In particular, if you do not regularly clean the fan with air duster, etc., dust and foreign matter may accumulate inside the fan, making the fan noise louder.

As you can see, the accumulation of dust and foreign matter inside your laptop is one of the main causes of fan noise. Regular cleaning will help maintain your computer's cooling capacity and reduce fan noise.

3. High temperature in the room

High temperature in the room is one of the main reasons why laptop fans become noisy.

Computers convert electrical power into thermal energy to perform operations. Therefore, the higher the environmental temperature, the more energy is required for cooling, the faster the fan spins, and the louder the noise.

For example, during the day in the summer or when used for long periods in a heated room, the environmental temperature rises and the fan rotates at high speed to cope with the rise. This may result in increased noise from the fan.

Therefore, high temperature in the room is one of the factors that increases the noise of the laptop fan. By using air conditioners and fans to maintain an appropriate temperature in the work environment, fan noise can be reduced.

4. Deterioration or failure of the fan

Deterioration or failure of the fan is one of the important reasons why laptop fans feel noisy.

Fans play an important role in cooling the heat inside your computer, but if used for a long period of time, they will wear out and deteriorate, reducing the performance of the fan itself. Additionally, if internal parts are defective or damaged, the fan may not function properly, causing it to spin at high speeds and generate noise.

For example, if the bearing part of a fan deteriorates, the fan rotation becomes unstable and abnormal noise is generated. Also, if the propeller part of the fan is damaged, it will also make more noise than usual.

From the above, aging or failure of the fan is one of the main reasons why the computer fan becomes noisy. If these problems are found, appropriate repair or replacement is required.

5. PC placement and environment

One of the reasons why laptop fans feel noisy is related to their placement and surrounding environment.

Computers require airflow, but for example, if the computer is placed in a place surrounded by walls or other objects, heat may not be able to escape sufficiently, and the noise generated by the fan rotating at high speed will increase. Masu. Also, if the temperature or humidity of the area where the computer is installed is high, the fan may work harder and the sound may become louder.

For example, if you use your laptop in a place with poor ventilation, such as on a bed or cushion, the bottom part of the laptop that is supposed to let the heat escape gets blocked, causing the fan to spin at high speed and make a lot of noise.

Therefore, the placement of your laptop and the surrounding environment have a big impact on fan noise. When using a computer, it is important to ensure sufficient ventilation and maintain appropriate temperature and humidity.
