Some products have higher requirements for the noise of the cooling fan, but they also need a relatively large air volume. What should I do if this happens? You can consider from the following two aspects
1. Choose a larger cooling fan and reduce the speed
2. The size remains the same, the speed is reduced
The size of the cooling fan is also 40*40*10mm. The first model is a public model, and the second model is a private model. The main difference between them is that the motor in the private model is smaller, and the fan blade is larger. This design has two advantages
1. At the same speed, the fan blade has a larger air volume
2. Under the same current, the speed of the private mold is lower and quieter (the motor is small, the running current is large, it is easier to start at low speed, and the speed can be lower)
