In order to reduce low noise during use, the following points must be paid attention to:
System impedance: Air flow resistance will cause air flow noise.
Turbulent flow of air flow: Due to the poor design of the flow channel, the turbulence of the air will have high-frequency noise. If the flow channel is not improved, it is difficult to improve quality.
Fan speed and size: The faster the fan speed, the better the heat dissipation effect. The larger the fan size, the greater the air volume and the better the heat dissipation effect. The higher the speed of the fan, the greater the noise, the larger the size, the greater the noise.
Temperature rise: After the temperature rises, the temperature difference decreases, and the heat dissipation effect decreases.
Vibration: Vibration will increase the noise of the fan, reduce the life span and reduce the speed.
Voltage fluctuation: Voltage fluctuation will cause the fan speed to change, make the work unstable and generate additional noise.
Design considerations: Other design requirements must also be taken into consideration to ensure the heat dissipation effect.
