What is the relationship between the voltage of the DC fan and the speed?

The DC fan is powered by a DC voltage. Commonly used DC fans have 5V, 12V, 24V, 48V. Does the voltage have a relationship with the speed? 1. A shaped DC fan, when the input voltage is lowered, the speed will decrease accordingly. Of course, when the input voltage is increased, the speed will generally increase. When the limit is reached, the voltage will increase and the speed will not change, just causing The current is higher, but the voltage is too high, the current is higher, and the motor chip may be burned. 2. The speed of the DC fan of the same specification and size can generally be higher at high voltage, and the power will be higher. 3. The voltage is higher. Low, the rotation speed can be made relatively low and can start, and the operation is quieter. Welcome to the heat dissipation classroom and news center of the cooling fan manufacturer again.
