When customers who are not familiar with cooling fans choose a cooling fan manufacturer for the first time, the first thing they know is the price, such as 4020 fans, Japanese imported or Taiwan first-line cooling fan brands are about 20 yuan, and Taiwan second-tier and mainland China The first-line brand 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 the quality of others is good, and they are indeed others. It is better. Most of the imported fans are ball bearings, the cost is higher, the life is longer, and the quality is more stable. 2. Domestic first-line brands are indeed much cheaper than imported ones, but the bearings are oil-containing 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 due to the poor reliability and stability of the products. 3. Why are domestic small processing workshops so cheap? In addition to low management costs, although oil-impregnated bearings are used in materials, there are deviations in the accuracy of the bearings, the accuracy of the chips, and the accuracy of other materials. Combining the above items, summarize In other words, 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 value, air volume, sturdiness, high pressure and high flow resistance, temperature resistance, use 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.
