The noise problem of cooling fans has been the focus of many consumers, especially when used in electronic devices, noise often affects the use experience. Different types of fans will produce different forms of noise during operation, mainly from the interaction between fan blades and air, fan motor operation and other factors.

dc cross flow fans are relatively quiet in terms of noise, because they use DC motors, which have less friction and vibration during operation. However, in the design of the fan blade, if the design is not proper, there may be a large airflow noise. Because the 12v cross flow fan is suitable for small equipment, when operating at low voltage, it may produce large wind cutting sound due to high speed or poor air duct.

tangential cross flow fans reduce noise through the tangential arrangement of blades and an optimized motor system. By improving the structure of the fan, such as using low-noise bearings and optimizing the shape and Angle of the blades, the noise generation can be effectively reduced.

In order to effectively deal with these noise problems, it is essential to choose high-quality fans and their accessories. In addition, reasonable air duct design, reduction of mechanical friction during fan operation and the use of silencing materials can also reduce noise levels to a large extent.
