Why the speed of the same batch of cooling fans is different?

In our understanding, the same batch of cooling fans should be the same. Why are the same batch of cooling fans at different speeds? When we are familiar with the speed test of the cooling fan, we will find that the speed is a dynamic and constantly changing parameter. This is because the resistance value of the motor changes slightly due to the influence of the environment. Therefore, the speed will always go back and forth in a small area. The beating of the same batch of cooling fans, different individuals, the resistance value of each cooling fan, the tightness of the structure, and the amount of oil. These subtle differences are caused by the variable value of the cooling fan made with the same parameter. For cooling fans above 4CM, it is normal that the speed tolerance is within 10% of the standard value. Of course, we can use special design and circuit interference to keep the speed in a constant state.
