How to make the 3007 DC cooling fan achieve a stable and silent effect?

For this ultra-thin cooling fan, more precision is required in assembly, and the material must be more refined and high-quality in order to achieve the effect of silence. What we often see is that cooling fan suppliers say that the effect of 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 is slow. Slow it out. The better way is to use more precise bearings, equipped 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. The cooling fan manufacturer can provide free samples for customers to try.
