Notebook computers are often used by us. They are very convenient for both work and study. However, if you want computers to be durable and have better performance, you have to maintain them well. The simplest and most important two points are dust cleaning and heat dissipation. Have users ever known about the natural enemies of computers? It doesn't matter. Now let's popularize the knowledge about computer natural enemies.
I. dust
Dust is the natural enemy of the computer. When our computer is used for a period of time, there will be a lot of dust in the computer, mainly in CPU fan, graphics card fan and power fan. Notebooks usually accumulate a lot of dust on the CPU fan and heat sink. At this time, how to deal with the dust? Note that if they are desktop computers and have strong hands-on ability, they can remove the CPU fan, computer graphics card and power supply, brush the dust off with a soft brush, and then blow the dust off the fan leaves with the cold air of the hair dryer. If they are not strong hands-on ability, please do not disassemble the computer parts, Put the whole chassis on the balcony or in an open place, and use the cold air of the hair dryer to blow the dust in the whole chassis. Of course, this does not use a brush. After brushing, the blowing effect is better, but it is still helpful for computer dust removal. The more dust, it will lead to the phenomenon that the heat sink does not dissipate heat when the fan blows the heat sink in the computer. Therefore, it is necessary to clean it when there is too much dust, Computer dust. If you are not a professional, it is generally recommended not to dismantle your laptop by yourself. It is best to send it to a professional to help you clean the dust. Generally, the cost of cleaning the dust in block letters is between 40-80.
II. Temperature
If the temperature is too high, it will also cause damage to the internal parts of the computer. If the computer is stable and does not crash without such and such inexplicable faults, reducing the temperature inside the computer host is a key problem. Then, how to cool the inside of the chassis? Add several heat conduction fans on the side and behind the chassis, add fans on the side of the chassis, import cold air, add fans behind the chassis and export hot air, In this way, a circular conductor is formed. In this way, the temperature of your computer host will drop. When the temperature is low, the life of computer hardware will become. According to incomplete statistics, 80% of computer hardware failures are caused by poor heat dissipation of the computer, resulting in damage to the motherboard, graphics card and CPU. Therefore, cooling the host is a good way to prolong the life of the computer. Due to the high integration strength of notebook computers, it is difficult to add fans. At this time, we'd better buy a slightly better heat dissipation base under the notebook to cool the notebook. The heat dissipation base 1. It can help you raise the notebook and expose the heat dissipation holes to the air. In this way, the heat dissipation must be better. 2. The heat dissipation base has its own fan, which can improve the heat dissipation of the notebook and is very good for the maintenance of the notebook.
