The commonly used cooling fan voltage is generally 12V, but some customers’ products, such as temperature-controlled cooling fans, set a lower voltage for the cooling fan at low temperatures. At present, when the voltage is low, the speed of the cooling fan is slower and more Be quiet. In order to design three different grades of air volume, some customers design three different voltages below 12V, so the cooling fan that does not work within the rated voltage range will be damaged if it is used for a long time.
Generally, the cooling fan working at 12V, as long as the supplier can ensure that it can work normally at low voltage and can ensure smooth start-up operation, there is no problem with the voltage lower than 12V, such as a high-speed 12V cooling fan, the voltage can be as low as 5V, or even 4.5 V can work, and the sound is quieter at this time
However, the 12V cooling fan cannot be used 10% higher than its rated voltage, such as 13.2V. It may exceed the power and cause the cooling fan to burn out, especially some high-volume, high-speed cooling fans, if it is possible to be higher than the rated Voltage, this requirement can be provided to the cooling fan supplier to expand the voltage range
