When customers who are not familiar with cooling fans choose a cooling fan manufacturer for the first time, they first understand the price, such as 4020 fans, imported from Japan or Taiwan's first-tier cooling fan brand is about 20 yuan, while Taiwan's second-tier and mainland China The first-line brand in China is about 4-8 yuan, and the price of small processing workshops in the mainland is only about 3 yuan. Why is the difference so much?
1. When buying imported fans, you may first say that their quality is good, and they are indeed better. Most of the imported fans are ball bearings, which cost more, have a longer lifespan, and have a more stable quality.
2. Domestic first-line brands are indeed much cheaper than imported ones, but the bearings are oil-retaining bearings, which are indeed inferior in terms of temperature resistance and dust resistance. Even if domestically produced double ball bearings are used, the price is actually much cheaper, mainly in terms of product reliability and stability.
3. Why is the domestic small processing workshop so cheap? In addition to the low management cost, although oil-impregnated bearings are used in materials, there are deviations in the accuracy of the bearing, the accuracy of the chip, and the accuracy of other materials
Combining the above items, in summary, no matter who makes it, the cooling fan will rotate and the shape is the same, but the difference is in some details, such as noise level, air volume, sturdiness, high pressure and high flow resistance. , Temperature resistance, service life, defect rate and other series reliability. Of course, this is not to say that the expensive ones must be good, and there are also some cooling fan manufacturers. The prices are very low, the materials are used well, the profits are very low, and the factory management is also very good. It just keeps profits low.
