The hidden dangers start with dust! Internal chassis fan cleanup is a coup

Dust as the number one killer of the computer has a serious impact on the life of the computer. Generally speaking, the computer after a period of time, the chassis will certainly have a lot of dust. Because of the current computer chassis for wind cooling, computer work, the fan rotation will continue to inhale the external air, to facilitate the internal components of the cooling. In the process of air circulation, dust enters the inside of the chassis with air and deposits around the fan.

Dust into the inside of the power box, will continue to accumulate in the power components and circuits, affecting the normal rotation of the fan, resulting in a strong noise, even in the heat of the affected circumstances damage computer components.

In this case, it is particularly important to periodically clean the dust off the fan. But for ordinary users, if the computer maintenance personnel or other professionals to clean the door, it is a bit of a fuss, wasting money. So ordinary users should learn to clean the dust around the fan themselves. So how exactly should be cleaned up, below we will be from the fan demolition, fan cleaning oil and heat sink clean three parts detailed explanation fan dust cleaning process.

Before we clean up, we must buy some cleaning tools: a small soft brush, screwdriver, towel, alcohol, oil, knives, toothpicks and so on. One brush, screwdriver, oil is an essential item.

Removal of fan and cleaning oil

Generally speaking, the power of the fan is the most difficult to clean, because the demolition is very troublesome. Here we give you a detailed explanation of the power supply fan demolition and cleaning. There are four screws in the power supply position on the back of the chassis, use a screwdriver to unscrew it, carefully take the power supply out of the chassis (remove the motherboard, hard drive, Magneto power cord before taking it off), then unscrew the four small screws behind the power supply, remove the power supply shell, and then use a screwdriver to remove the power supply fan.

It is relatively easy to handle the dust of fan blades first with a brush. In order to eliminate the noise, we also need to add lubricating oil to the roller parts of the fan. Use a screwdriver to carefully peel the sticker behind the fan, exposing the rubber stopper.

Use a smaller screwdriver or toothpick to take out the rubber plug, then you can see the fan bearing, and then carefully drop a few drops of lubricating oil, the rubber set, the back of the sticker back to the original place.

Manually rotate the fan to allow the lubricant to seep into the bearing. Finally installed the fan, when the computer runs for a few seconds, the lubricant evenly distributed around the bearing, the noise is reduced, the fan cooling effect better.

Clean the heatsink and summarize

Because the heat sink is more dense, so it is difficult to clean up. We first use a rag or brush to clean the surface of the heat sink a large area of dust, and then put the heat sink into the alcohol immersion. This allows the bulk of the dust stuck in the gap in the heat sink to soften and make it easier to clean up.

Split the swab or toothpick with a knife and use it to clear the dust in the heatsink to carefully clean each one.

After that, remove the heat sink into the alcohol again to ensure that no dirt is left in the heatsink. Because of the deep gap in the heatsink, the alcohol is not easy to dry, so it is best to put the heatsink in front of the fan dry, and then install.

Summary: The entire cleanup process is not as difficult as it might be, and ordinary users can easily learn. Make a comprehensive cleaning of your computer over time to ensure that the computer is more stable and more effective in prolonging the life of the computer. In addition to cleaning up, should also learn to prevent dust, the use of computers is best not to smoke, because the damage to the computer is very large. Use the computer, cover cloth will be the display and chassis, can also effectively suppress dust.
