The noise issue of cooling fans is a major concern for many users. Based on WELLSUNFAN's experience for the research, developmen, and production of high quality cooling fans, here are some methods to reduce the noise level of cooling fans:
The range between the air inlet and outlet of one casing accounts for 60% to 80% of the total system impedance.
Higher system impedance requires greater airflow for cooling, so to minimize the noise, the system impedance must be reduced to the minimum.
The obstacles encountered along the airflow path produce noise.
The air inlet and outlet of the cooling fan must avoid any obstruction to reduce noise.
High-speed fans make more noise than low speed fans.
It is advisable to select larger fans with lower rotation speed, as they are quieter when delivering the same airflow.
The required airflow for cooling is inversely proportional to the allowed temperature increase.
A slight increase in temperature can reduce the required airflow and noise.
Use soft isolation materials to avoid transmitting vibrations.
This is particularly useful when the whole system is lightweight or needs to operate in the specified way.
High voltage can increase fan speed, vibration, and noise.
It is advisable to choose fans with lower voltage.
