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

1, people often compare wind pressure and air volume when choosing cooling fans. Normal ventilation, wind pressure and air volume need to overcome the resistance of the cooling fan ventilation stroke, the cooling fan must produce pressure to overcome the resistance of air supply. It is the air pressure. Air pressure depends mainly on the shape, area, height and speed of the fan blades. The faster the rotational speed, the larger the fan blades. The higher the wind pressure, the more the air duct design of the heatsink 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 use some very special designs, which can better meet the needs of users by applying newer technologies and techniques. In terms of dust prevention, cooling fans will be covered with a thick layer of dust on all parts of the airflow after long-term use.

3. The total amount of air delivered or drawn in by the cooling fan per minute. Airflow is an extremely important indicator of an air-cooled radiator's ability to dissipate heat, given that the radiator materials are the same.In other words, the larger the fan, the greater the airflow.Therefore, a larger airflow can take away more heat per unit of time.If the air volume is compared to the power of a weapon swing, then the wind pressure is the sharpness of the weapon.Other conditions remain unchanged, the actual air volume plays a decisive role in the effectiveness of the cooling fan.


4, in the choice of cooling fan, we need to know is that the more vertical cooling fan fan blades, the greater the wind cross-section, the greater the amount of wind generated, the greater the wind shear noise; less wind, heat dissipation, not to mention. The number of fan blades and the design of fan blades will also have a great impact on the air volume and wind pressure.The design of cooling fan blades has a significant impact on fan performance.

At the same speed, a product with excellent blade design can provide greater air pressure and air volume, thus producing better heat dissipation.

Another thing we need to understand is that for a cooling fan to have a strong performance, the fan needs to be handled in every detail in order to deliver Z-best performance. It will sacrifice the air pressure of the cooling fan with high airflow. When the air pressure is high, the airflow will be reduced, and the speed of the cooling fan is not necessarily related to the cooling capacity.
