Cooling fans can be divided into low-noise fans, high-volume fans, waterproof fans, silent fans, etc. according to their different functional characteristics. Using different centers, the fan's functional requirements are different. Other fans are well understood. As for what a silent fan is, and what is special about it, many friends will ask that the silent fan can really be silent. Is there no sound?
Silent fans are mainly used in household appliances and quiet electrical equipment. The advantage is that the noise of the fan is smaller and more stable than similar fans. After damping, reducing the speed, and optimizing the motor, the fan can achieve a silent effect. It is mainly composed of three parts: bearing, speed and blade.
The working mode of the silent fan: its thermal conductivity, copper contacts and heat pipes are better than aluminum alloy. The shock absorption effect of the overall structure. The intelligent temperature control mute module is used to effectively control the fan speed. The fan speed is controlled within a certain range to ensure ultra-low speed operation of the fan. The separated shock absorption design prevents vibration and noise to the maximum extent, thereby greatly improving the noise of the fan.
Of course, as they said, there is no sound at all. That is impossible. At least the fan blades rotate and you should be able to hear it when you sleep, just like the sound of a notebook.
