For this ultra-thin DC cooling fan, more precision is required in assembly, and the material must be more refined and high-quality in order to achieve a silent effect.

 

What we often see is that the suppliers of DC cooling fans say that using oil-impregnated bearings is very quiet, but the accuracy of oil-impregnated bearings is not enough. In the case of more lubricating grease, the sound is still very good. When the grease is less, the noise Just come out slowly.

 

The better way is to use more precise bearings with precise shaft cores, and then make the balance better. A more secure approach is to use double ball bearings. This structure is stable and the sound can be kept silent for a long time. Yirongchuan Technology can provide free samples for customers to try.

 

Since Yirongchuan Technology, a manufacturer of DC cooling fans, has been engaged in production and processing, experience tells us that the kind of customers who are looking for stocks are mainly composed of two parts. One part has never used a DC cooling fan, and the other part is a trader. They don’t understand the production characteristics of DC cooling fans

 

Why are DC cooling fans not stocked in stock? It is because customers do not agree with the specifications set by the manufacturer’s own standards. We are currently in a period of tailor-made for customers, not what is produced in the factory. Customers use what specifications. Therefore, the DC cooling fans that have become stocks for reasons of this and other reasons are often unable to be shipped for several years, and then become eternally sluggish products. The factory dismantles the cooling fans and leaves the accessories for production. Other specifications.

 

As long as the manufacturers of DC cooling fans confirm the specifications, they can actually make products quickly, about 20 days or so. This is tailor-made, and the cooling performance of the product is more stable.
