The laptop fan is loud

Method 1:

Lubricate the bearings and oil the fan

The most important part of the fan transport It is the bearing that lacks lubricating oil over time, which will produce noise when rotating at high speed. Therefore, we only need to put a few drops of lubricating oil on the fan bearing, which can be replaced if a sewing machine is not used.

Method 2: Fixed fan blade

Vibration noise It is also an important component of fan noise. Because the blades are loose on the bearings and the bearings are worn, the gap becomes larger. Therefore, you only need to remove the fan and tighten the screws. After it is firmly fixed, it will no longer vibrate. .

Method 3: Polish the fan blades

In addition, the quality is better Poor cooling fans. Due to process defects in the production of such fans, the center of gravity of the fan blades may not be on the axis, resulting in "eccentricity". Over time, the "eccentricity" of the fan will become worse and worse. The more serious it is, this will not only produce noise, but may also damage the CPU. In this regard, you can dismantle the cable and hang it in the center with a thin wire. After it is still, see which direction it sinks. Gently grind the sinking end on the grinding wheel for a few times, and then test it. Wait until the fan can be in a horizontal position before installing it.

Method 4: Clean the fan

Prepare a medium-hard brush, air pump or hair dryer. In order to prevent static electricity on our hands from damaging the power supply, it is recommended to hold a large metal object, such as a metal railing.

Hold a hair dryer in one hand to blow against the fan, and hold a brush in the other hand to dust If the fan blade can be removed, it is best to clean it with clean water.

Method 5:

Sometimes the power screw is screwed If it is not tight, resonance will occur, resulting in slight noise. It is recommended to check whether the power supply is stable and suitable for installation.

Method 6: High fan speed

New The reason why the fan sound is loud is often caused by the high speed of the fan, especially the original fan. The area of ​​the fan blades is relatively small and the number of aluminum heat dissipation fins is small. In this way, if the heat is high, in order to ensure that the processor If the temperature is not too high, you must increase the speed of the radiator fan.

The first method is to replace the large fan blades and large cooling fin area, use A better heat-conducting metal radiator will reduce the fan speed and reduce the noise.

The second method is to manually adjust the speed of the processor fan to make it less noisy Fixed speed.
