Cooling fan manufacturers tell you: how to choose a good quality cooling fan ?

1. When people choose a cooling fan, they often compare the air pressure and air volume. For normal ventilation, air pressure and air volume need to overcome the resistance in the ventilation stroke of the cooling fan, and the cooling fan must generate pressure to overcome the air supply resistance. is wind pressure. The wind pressure mainly depends on the shape, area, height and speed of the fan blade. The faster the speed, the larger the fan blades. The higher the wind pressure, the better the air duct design of the heat sink can maintain the wind pressure of the fan.

2. In terms of design, in addition to the general design mentioned above, some cooling fans also adopt some very special designs, which can better meet the needs of users by applying updated technologies and processes. In terms of dust protection, the cooling fan will cover various parts of the airflow with a thick layer of dust after long-term use.

3. The total amount of air delivered or drawn in by the cooling fan per minute. In the case of the same radiator material, the air volume is an extremely important indicator to measure the heat dissipation capacity of the air-cooled radiator. That is, the bigger the fan, the bigger the air volume. Therefore, a larger air volume can take away more heat per unit time. If air volume is compared to the power of a weapon's swing, then wind pressure is the sharpness of the weapon. Under the condition that other conditions remain unchanged, the actual air volume plays a decisive role in the effect of the cooling fan.

4. When choosing a cooling fan, what we need to know is that the more vertical the fan blades of the cooling fan are, the larger the wind cross-section, the greater the air volume generated, and the greater the wind shear noise; the less wind, not to mention heat dissipation . The number of fan blades and the design of the fan blades will also have a great impact on the air volume and wind pressure. The design of the cooling fan blades has a significant impact on the performance of the fan. At the same speed, products with excellent blade design can provide greater air pressure and air volume, resulting in better heat dissipation.

In addition, what we need to understand is that in order for the cooling fan to have strong performance, it needs to handle the fan in every detail in order to exert the best performance. Air pressure of a cooling fan that sacrifices high air volume. When the wind pressure is large, the air volume will decrease, and the speed of the cooling fan is not necessarily related to the cooling capacity.
