When the customer’s product requires quietness, the built-in cooling fan must be silent. First of all, we must understand the silent fan. It is not silent, but under the same conditions, it is quieter than other conventional cooling fans. For example, the air volume of 30CFM is also reached, but the conventional cooling fan is 40db, but the noise of the silent fan may be only 30db, the heat dissipation performance is the same, but it is quieter
Jingyangda has some specifications that are quiet, such as 2006, 2010, 2507, 2510, 3007, 3510, 5010, 7010. These models have the characteristics of large air volume and low noise when the fan blades are running in the mold design. , Our company lists them as silent fan series
In addition, for ultra-thin cooling fans, such as 2006.2010, 2507, 3007, 4007, most customers come to us because the fans they used before are noisy, and some may be 1 month. It may be half a year, and the number of noises is increasing. The main reason is that they are making ordinary oil-containing bearings. The precision is poor, and the noise is coming when the oil is dry. In order to solve the noise problem of small fans below 10mm, our company adopts double ball bearings imported from Japan, which have good dust resistance, high temperature resistance and high precision, but the price is also high, and the service life is as long as 50,000 hours. It can be used for about 30,000 hours even in a high temperature environment of 60 degrees.
