What are the four important indicators of waterproof fans? Many people don't know this. If they don't, then let's take a look.

1. Air volume

The air volume is the volume of air discharged by the waterproof fan per second, and it is one of the most important indicators to measure the cooling capacity of the waterproof fan. The larger the air volume, the better the cooling capacity of the cooling fan.

2. Wind pressure

Air pressure and air volume are completely different concepts. is also relative. Wind pressure means that the waterproof fan needs to overcome the resistance in the ventilation stroke of the fan for normal ventilation. The air volume of the waterproof fan is large, and the wind pressure will be low. The higher the air pressure, the lower the air volume. Large air volume can drive a large amount of air flow, but small wind pressure, the wind cannot blow to the bottom of the radiator, and the heat dissipation effect is not good. Ineffective.

3. Speed

Rotational speed refers to the number of times the fan blades rotate per minute, and the unit is rpm. This is relatively straightforward.

4. Fan noise

Working noise is also a very important indicator. It is generally required that the noise of the fan should be as small as possible, and there should be no abnormal sound.
