Use' Heat exchange fan 】 Pay more attention to, it will be more and more quiet

Belongs to the internal mechanical cooling ac fans, will inevitably be just a mechanical noise, do about appear noise, we can pay more attention to in the process of using points:
system impedance: airflow resistance can cause air noise.
air turbulence: due to the bad flow channel design, there will be air turbulence, if the port is not improved, it is difficult to improve a lot.
the fan speed and size, the faster the fan speed, better heat dissipation effect, the greater the size of the fan, air volume, the greater the heat dissipation effect is better. The higher the speed of the fan, the greater the noise, the greater the size, the greater the noise.
temperature: if the temperature after temperature decreases, and the cooling effect will be reduced.
vibration, vibration will lead to fan noise increases, shorten the service life and lower speed.
voltage fluctuation, voltage fluctuation causes fan speed change, make run unstable and generate additional noise. Design considerations: must also consider other design requirements, to ensure the heat dissipation.
key to note the above points, the noise will leave you, will not affect your life.
