A. Cooling fan speed

 

The speed of the cooling fan is also a factor that determines the air volume of the cooling fan. The higher the speed of the cooling fan and the power, the better. However, if the speed of the fan is higher, the noise and vibration will increase accordingly. Therefore, if the air volume is sufficient to dissipate heat Under certain conditions, it is better to choose a cooling fan with a low speed as far as possible.

 

B, cooling fan power

 

If you don't need a strong heat dissipation effect, you can choose a relatively small power. The higher the power of the cooling fan, the stronger the wind, and the better the cooling effect. Of course, it is not entirely that the higher the power, the better. We need to make a comprehensive comparison based on the material and working principle of the fan. According to the actual situation, the high-power cooling fan will naturally consume more energy.

 

 

C, cooling fan material

 

Generally, there are two main materials for cooling fans on the market: plastic/aluminum. Generally, the materials of DC cooling fans are plastic, while aluminum fans are AC fans. The cooling effect of the AC fan is lower than that of the DC cooling fan, and the air volume is small.

 

D, cooling fan noise

Many cooling fans with poor quality will make a lot of noise due to bearing wear or other reasons after a period of use, which will not only affect the service life of the fan, but also make people feel irritable. It is recommended to choose a brand with strength when purchasing a cooling fan. The quality will be guaranteed only if the manufacturer purchases it.
