The power supply voltage of each product that uses a cooling fan may not be the same. Some use 5V, some use 12V, and some use 24V, 48V. Many customers will ask whether the cooling fan powered by 5V is not as large as 12V. ? The air volume is actually related to the speed. If the speed of 5V and 12V are the same, the air volume must be the same for the same mold, but the current at the same speed of 5V will be higher than the current of 12V. For high air volume and high speed, 12V power supply The speed can be higher, and 5V may not be able to do as high as 12V. In this case, the air volume of 12V is basically higher than the limit air volume. Therefore, when we decide to use a certain cooling fan shape mold, if we want a higher speed, choose a higher voltage, maybe the speed can be higher, and the air volume will be higher.
