CPU fan refueling method

1: Remove the fan;
2: Place it on the table and carefully peel off the sticker on the back;
3: Take out the rubber plug. If you use a small screwdriver, it is easy to take out and put in the plug;
4: Add a few drops of lubricating oil; Put the rubber cover back and stick the sticker on the back back to its original place. If the sticker is not sticky, you can stick it with a small amount of glue. Turn the fan to let the oil seep in. After the fan is installed, when the computer runs for a few seconds, the oil will enter the metal hole and then enter the cylinder. You will find that the fan rotates faster and quieter than before. Not only does it reduce the noise of the fan, but it also extends its service life.
