1. Step 1: Prepare the tools to be used before dust removal. Screwdrivers, brushes, silicone grease and hair dryers are necessary. Don't take apart the computer and find a few tools and then find or buy them separately. In addition, it is better to prepare insulating gloves, which can play an anti-static role.

2. Step 2: Turn off the laptop and unplug the power plug. Then you can use a screwdriver to unscrew the screws on its back cover. After all the screws are unscrewed, remove the back cover. Find the battery of the laptop first and remove the battery first to avoid that the battery is still supplying power to other parts.
3. Step 3: After that, you need to find the position of the fan. There will still be screws here. You need to unscrew the screws with a screwdriver, and then remove the fan to start dust removal. When cleaning, use a hair dryer to turn to the cold air to blow away the dust outside, and then use a brush and flannel to wipe the dust inside.
4. Step 4: After the dust is cleared, remove the residual silicone grease on the CPU, and then apply new silicone grease. After the fan is installed back to its original position, tighten the fan screws, remember to fix the fan, and then replace the notebook battery and cover plate, and screw the back cover plate screws.
5. Step 5: Power on test. Finally, you can turn on the laptop and start it to test the effect of dust removal. Normally, the temperature of the laptop will drop significantly after dust removal, and the noise will also decrease. However, if the temperature drop is not obvious, you need to check whether it is caused by other reasons.
What's the matter with the loud noise of the laptop fan after dust removal
After cleaning the laptop fan, I found that the main reason for the loud noise may be that the parts inside are not fixed properly, such as the screws of the fan are not tightened, which causes it to shake and make a noise. Therefore, when cleaning, it must be better to restore the clothes. If you feel that the dust removal is not good, you can ask the computer shop staff to deal with it.
