Will the 12V cooling fan be damaged if the voltage is lower than the rated voltage?
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 under low voltage, can ensure smooth start-up and operation, the voltage is lower than 12V, there is no problem, 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, but the 12V cooling fan cannot use 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 air volume and high speed. If it is possible that the cooling fan is higher than the rated voltage, you can provide the cooling fan supplier with this requirement to expand the voltage range.
