The chassis is the carrier of most parts of the computer, generally including the shell, brackets, various switches on the panel, indicator lights, etc. The chassis is part of the computer accessories, and its main function is to place and fix the computer accessories. Support and protection, after the computer is used for a long time, the speed of the cooling fan is likely to decrease, and the cooling capacity is reduced. The main reason is that a large amount of dust is accumulated inside the chassis. There are many dust particles in the incoming air. If the surface temperature of the internal components of the computer is higher than the temperature of the air drawn in, these dust particles are easily adsorbed on the surface of the device. Over time, the dust will form a layer of dust film on the surface of the components. This layer of film will directly affect the heat dissipation effect of each component. As the dust inside the computer accumulates on the board inside the computer, the dust will accumulate on the exposed pins of the computer's internal components, especially in the humid season. The dust will form a plate with moisture on the board, and the accumulated dust will form a conductor to short-circuit the board, and in severe cases, it may burn the components.
