How to clean the dust of the fan on the computer, and how to deal with the dust of the computer fan

You need to go to the computer *** to hand over to the after-sales cleaning, and there will be some trouble in cleaning it yourself

1. Open the main chassis: first unplug all the wires of the main chassis. There is no need for a screwdriver here, and the general main chassis can be unscrewed directly by hand, here are four large screws, use your hand to unscrew it to the left (loose left and tighten it right), and then remove the main cover on one side by hand.

Just go to the side piece.

2. I have a piece on the right side (a piece with heat dissipation holes).

3. Remove the radiator: After opening the main chassis, you can see the radiator, which is a small electric fan, and you need to remove it. Rotate a few knobs around the radiator in the same direction (generally loose left and tight right), and then hold the radiator with your hand, and you can take it out with a little force (it is easier to swing left and right).

4. Remove the metal sheet of the radiator: After removing the radiator, there is a sheet of metal on the radiator, which has a lot of dust in it, and it only takes a little effort to remove this radiator, rotate it left and right, and rotate it outward to take it out.

5. Clean up the dust of the radiator: after the heat sink is removed, you will see that there is a lot of dust inside, which affects the operation of the radiator, thereby affecting the heat dissipation effect. Use a brush to clean up, and then use a hair dryer to blow it until the dust is cleaned.

6. The radiator dust is cleaned up: it will be cleaned up soon, it is better to use a combination of a brush and a hair dryer, the brush will brush down the dust or the brush is loose, and then the hair dryer will hang down, and it is best to use a hot gear to use the hair dryer, but not too hot (medium heat).

7. Clean up the CPU and motherboard dust: The dust is mainly concentrated on the radiator, but there is still a lot of dust on the motherboard and CPU, use a brush to brush off most of the dust or loosen the brush, and then use a hair dryer to blow (medium heat is better) until the motherboard and CPU are cleaned up.

8. Clean up the CPU and motherboard: After cleaning, the CPU should be bright and the dust on the motherboard should be less, so that it is completed, and after the cleaning is completed, you can install the radiator. Apply thermal grease to the CPU.

9. Install the radiator: This is the key, when installing, it is not as easy to get as when you take it off, here is a little trick. Turn several fixed knobs to install the radiator in the same direction (generally loose left and tight right), loosen, and then align the radiator with a few empty inside, insert a few holes into it first, use a screwdriver to press and hold a tubular thing at the bottom of the fixed foot, and then press and hold the remaining fixed foot into it.

The main thing is the dust situation on the heat sink of the CPU fan, if the gap is almost blocked, then it is not necessary to clean it, if there is only a thin layer of dust, it doesn't matter if you don't clean it; If you want to clean up, you can use a small paint brush, the key is to clean up the dust of the CPU fan, the dust of the graphics card heatsink (if any), and the dust of the motherboard heatsink, first use a small brush to reverse the dust floating, and then use the cold air speed of the hair dryer to blow off the dust (this should be done indoors), if the memory slot is to be unplugged and then cleaned up, but either not to clean up, to clean up must be cleaned as much as possible, otherwise it is easy to have the following situation; Try not to move the dust in the power supply, and if you don't have a professional tool, it will damage the power supply. The most likely situation after cleaning is that some boards, poor contact of memory, there is a situation that can not be turned on, re-inserting and removing the board can generally be solved, it seems that you are not familiar with the computer hardware, it is recommended to ask a professional to clean it.

1. A set of screwdrivers, often the screws in the notebook are of different sizes, and a set of screwdrivers needs to be prepared to be able to prescribe the right medicine, and the screwdriver is a tool, so be prepared. I myself use a set of screwdrivers from Nanqi, and by the way, I also have a cheap set in case I need them. It is also possible to use a screwdriver with Xiaomi.

2. Silicone grease, since the ash is disassembled, then replace the silicone grease by the way, after all, the silicone grease is almost dry after two or three years, and I often prepare the silicone grease for the people.

3. Notebook cleaning suit. Generally speaking, many notebook cleaning kits contain: crowbars, brushes, tweezers, screen cleaning spray, anti-static gloves, screw storage boxes, suction cups, brushes, etc. (each has its own purpose, basically you will know what tools you need after getting started), and there will be a set of screwdrivers in the ash cleaning set, personal advice is that if you don't use it often, this set of screwdrivers is enough, if you use it often, it is better to change the set, because the screwdriver itself is not very strong, and it is easy to screw the screws on the notebook.

1. Use a screwdriver to remove the screws on the trapped strip of the Zhengchun windshield, remove the trapped, and then remove the outer half of the hood.

2. Twist the big screw that fixes the fan blade, screw it out, you can remove the fan blade, and use the large air volume of the hair dryer to blow off the dust that can be blown off.

3. Wipe off the dust on the windshield with a wet rag, inside and out, and then wipe off the dust on the fan blades with a rag.

4. Align the fan blades with the motor shaft, install the fan blades, and tighten the big screw with a wire. Pay attention to the direction and then put the windshield up, tie it with a trap strip, and screw it; It is recommended to remove dust and maintain the fan once every 2 months.
