The reason why the fan is not windy is as follows:
The first point may be that the electric fan has not been cleaned for too long, and the electric fan is rotating but there is no wind. The fan surface and air outlet of the electric fan that have not been cleaned for too long will attach a large amount of dust and other debris, which will block the air outlet of the electric fan, and will also cause the speed of the electric fan to weaken, so that the wind power of the electric fan will be reduced. When you have free time, you can turn on the electric fan and clean and wipe the fan blades, air outlets, protective nets and other parts inside.
The second point may be that the motor lubrication of the electric fan is not good, the motor can not drag the fan blades, and after removing it, it will be found that the shaft can still operate normally, which means that the fan motor is not broken, but the motor lubricating oil is insufficient, resulting in insufficient speed of the electric fan and less air outlet. You can turn on the electric fan and apply some lubricating oil to the motor of the electric fan.

This is because the heat sink is blocked or the fan shaft is too sludge to rotate, and the fan needs to be disassembled and cleaned, and the fan shaft is cleaned and refueled. However, this requires good technical techniques, because if the technology is not good, the heat sink and chip may not be able to stand up or the silicone grease will not work, etc., and the heat dissipation effect will be worse.
The fan rotates but there is no wind because the fan blades are not installed tightly, and it is OK after fixing it tightly. If you can't do it, you can only replace the fan blades, which are seriously deformed during operation, and the deformation is out of balance, so there will be wind in both front and back. The balance is lost, the load increases, and the electromechanical sound becomes louder.
Take out the fan blades, put a little sewing oil on the motor shaft, and replace the fan blades is completely solved.
If the rotation is flexible, mostly caused by the decrease in capacitor capacity, or the motor coil has an inter-turn short circuit fault, first replace a new capacitor with the same capacity to try it, if it still doesn't work, then use a multimeter to measure whether the resistance of the motor coil is normal, otherwise you should replace the new motor or buy a new fan.

There are several reasons why the air volume of electric fans is getting smaller and smaller:1. The fan blades carry too much dust, resulting in a decrease in speed;
2. There is too much dust on the shell cover, resulting in unobstructed air duct;
3. The motor is aging, resulting in a decrease in speed.
Precautions for electric fans:
When the electric fan is working (assuming that there is no heat transfer between the room and the outside world), the temperature in the room will not only not decrease, but will rise.
When the electric fan is working, because there is an electric current passing through the coil of the electric fan, the wire is resistive, so it will inevitably generate heat and release heat to the outside, so the temperature will rise.
When the electric fan is in operation, the air in the room will flow, so it can promote the rapid evaporation of sweat, and in combination with the fact that "evaporation needs to absorb a lot of heat", people will feel cool.

The reasons are several situations: 1. It may be that the fan blades are reversed. 2. The reverse side of the electric fan may be too close to the wall, resulting in air inability to convection.
3. The internal resistance of the motor will become larger after a long time, and the load can become lower, resulting in the inability to drive the fan blade to rotate, and the excessive shaft clearance of the motor will also cause the fan blade to not rotate. Solution: 1. It will not affect the electric fan, it can still rotate, but there is no wind, you only need to disassemble the fan blades and reinstall it to deal with it.
2. Move the electric fan to a ventilated position. 3. Replace the motor with a new one. 4. Add an appropriate amount of smooth oil to the motor.
5. Repair the front elevation angle of the fan blade (repair it with a hair dryer) or directly cut the deformed part of the front elevation angle with scissors. 6. If you have just bought it, it is recommended to replace it again. The old fan is sent for disposal.
7. Check whether the fan blades of the electric fan are installed and fastened, and tighten and fix them in time if they are loose. 8. Check whether the fan blade is not the original fan blade, if the fan blade is too small, it will also lead to no wind, and it should be replaced with the fan blade of the original machine. 9. Check whether the surface of the fan blade is dirty and clean it in time.

The reasons why there is no wind in the electric fan are as follows:1. The fan blade is not tightened well, if it is loose, tighten and fix it in time.
2. The fan blade is installed in the wrong direction and needs to be removed and reinstalled.
3. The fan blade is not the original fan blade with poor stirring ability, if the fan blade is too small, it will also lead to no wind, and it can be replaced with the fan blade of the original machine.
4. If the fan blade is damaged, resulting in the weakening of the wind leakage, the new fan blade can be replaced in time.
5. The surface of the fan blade is too dirty, resulting in weak wind, so clean it in time.

1. It may be caused by the fact that the electric fan has not been cleaned for too long, and a large amount of dust will be attached to the fan surface and air outlet of the electric fan, resulting in the weakening of the speed of the electric fan. In this case, you only need to clean the fan blades, air outlets, protective nets and other parts.
2. It may be that the motor lubrication of the electric fan is not good, and it cannot be caused by the fan blades. If the shaft can still run normally, it proves that the motor is normal, but the motor lubricating oil is insufficient, resulting in the slow speed of the electric fan and less air outlet, as long as the motor is coated with some lubricating oil.
3. The age of the electric fan is too long, and the gap is too large after the wear of the shaft sleeve of the motor, which makes it impossible to drag the fan blade load, resulting in the motor being easy to burn out, making the internal resistance of the motor larger, and unable to drive the fan blade to rotate.

If there is no wind in the electric fan, it is generally a problem with the motor!
Fan. The causes and solutions for turning but no wind are: >>>More
Electric fans make people cool, but if they are turned on frequently, they will cause a series of symptoms such as sneezing, runny nose, fatigue, headache, dizziness, insomnia, shoulder pain, and loss of appetite, which is "fan disease". Electric fans can speed up the evaporation of sweat, making people cool and comfortable. However, due to the constant and variable speed of the fan, the airflow and vibration are carried out at a fixed frequency, so it is not as gentle as natural wind. >>>More
Memory doesn't work, graphics cards don't work, LG monitors don't work. >>>More
Reason]: 1. After using the electric fan for a long time, we must first see whether the motor lubricating oil is still there, if the motor lubrication is not good, there will generally be noise, and the more serious thing is that the fan does not rotate. In the event of a power outage, if you pull the fan blades with your hands, the fan will also be a little stiff. >>>More

Blocked, the heat dissipation capacity is very low, the temperature of the laptop is high, and it keeps turning. >>>More
