Same speed, same voltage, same airflow. Cooling fans with lower current are better. The smaller the current, the less fan wear and the lower the power consumption.

Currently

Same speed, same voltage, same airflow. Cooling fans with lower current are better. The smaller the current, the less fan loss and the lower the power consumption. The main reasons for low power consumption are:

<1> The product has strong magnetic conductivity

<2> Motor enameled wire has low loss

<3> High copper content

<4> Lubricating oil has high reactivity.

Listen to noise

At the same speed and voltage, cooling fans with lower noise perform better because low noise is mainly related to fan blades, bearings, oil, assembly structure, etc. The better the blade shape design, the greater the airflow and the lower the noise. This is not only a technical task but also a test of the technician's ability. The higher the precision of the bearing, the less friction with the shaft core, the more accurate the size matching, and of course the lower the noise. This is greatly related to the bearing material. Low noise means less friction, longer bearing and shaft core life, and longer DC fan life.

Vibration measurement

For fans of the same specifications and speed, cooling fans with less vibration perform better.
