The noise level of the cooling fan affects people's normal life. The cooling fan in operation will produce noise, which is acceptable in a certain range. However, as the fan is used for a long time, the noise will become larger and larger, so how to avoid excessive noise?

1. When selecting the cooling fan, the fan with lower speed is selected under the condition of cooling fan, and the noise of the fan with larger size is smaller than that of the fan with higher speed and smaller size conveying the same air volume.

2. When the fan is running, the air flow obstruction will produce noise, and the air inlet and outlet need to avoid obstruction.

3. The voltage of the cooling fan will also affect the noise. The higher the voltage is, the higher the speed will increase the vibration of the product, so the noise will also increase.

4. The design of each fan parts will affect the noise level, so we need to consider the noise reduction, winding, blade and fan frame design, accurate manufacturing and balance.

The above is a brief introduction to the temperature resistance of DC axial flow fans. I hope it can help you.
