Notebook noise is driven away from the reason why the notebook fan does not turn on at boot

The notebook is long, there will be some maintenance problems, and a small problem! Most of the problems with notebooks are caused by CPU overheating! That is to say, the fan of the notebook is prone to problems! Specific small problems such as: notebook noise, laptop fan when turning on the phone will not turn anymore! In the face of these notebook fans, when they turn on the boot, they will never turn and the notebook is noisy. The reason for this article is to find out some notebook noise methods and the notebook fan turn around when you turn it on. The reason for not turning, for the user's reference!

Notebook Noise Removal Method

The notebook fan is different from the desktop fan. The general desktop fan is when you turn on the power, the fan starts running at high speed; the notebook is exceptional. Generally, the fan only starts to rotate when the temperature reaches the predetermined limit of the BIOS, and it is often not fully operated, and is divided into several speeds to run. This is also considered for the purpose of power saving and noise reduction. Generally, used laptops are used for a long time, and a large amount of dust and dirt accumulate inside the fan. When the fan rotates, the sound is particularly loud due to the blockage of dust. Sometimes the dirt may entangle the fan blades and the fan cannot be used. The normal work, the consequences are unimaginable. Since there is no uniform standard in the industry, the internal structure of each notebook is different, so replacing the new fan is not realistic for the notebook. The simplest solution is to clean the fan by yourself. The method is to use a clean cotton ball. Alcohol carefully cleans each blade and the center of the shaft. It is important to note that do not add any lubricant to the fan shaft. This is mainly because the notebook fan is different from the desktop fan. It uses a high-grade fan in a self-lubricating form. It is different from the common ball fan, so it is not only the oil. Without any effect, it will affect the normal operation of the fan.

After the dust is cleaned, we also need to consider the problem of thermal deformation of the fan. Because the fan rotates at a high speed for a long time and blows hot air to achieve heat dissipation, the plastic leaf surface will be thermally deformed. As I mentioned above, it is not possible to replace the fan. We can consider the method of cutting off the deformed fan properly, so that the noise problem caused by the uneven operation of the blade can be solved.

Why does the notebook fan turn around when it is turned on?

Due to the temperature control design of the notebook computer, the boot notebook fan will stop rotating after self-test, and will only accelerate when the machine reaches a certain temperature, which is why when you carry out high-load work, such as The reason why the high-definition rate video and the high-speed rotation of the fan during 3D games are played.
