You know, the price of the product determines the quality of the product, when you are not familiar with it.DC cooling fanWhen choosing a cooling fan manufacturer for the first time, the first thing we know is the price. For example, the DC cooling fan 4020, the cooling fan brand imported from Japan or Taiwan is about 20 to 30 yuan, while the first-line brands in Taiwan and the mainland are about 4 to 8 yuan. The price of small processing workshops in the mainland is only about 3 to 4 yuan. Why is there so much difference?

1. Buying imported fans may first say that people's quality is good, and indeed people's are better. Most imported fans are ball bearings, which have higher costs, longer life and stable quality.

2. Domestic first-line brands are indeed much cheaper than imported ones, but the bearings are oil-bearing bearings, which are indeed worse in terms of temperature resistance and dust resistance. Even if the domestic also use double ball bearings, in fact, the price is much cheaper, mainly in the reliability and stability of the product is still poor.

3. Why are domestic small processing workshops so cheap? Apart from low management costs, oil-bearing bearings are also used in materials, but there are deviations in the accuracy of bearings, chips and other materials.

Combined with the above items, in summary, no matter who does it, the cooling fan will rotate, and the appearance is the same, but the difference is in some details, such as noise value, air volume, firmness, resistance to high pressure and high flow characteristics, Temperature resistance, service life, defective rate and other series of reliability. Of course, this is not to say that the expensive ones must be good, nor are some cooling fan manufacturers. The selling price is very low, the materials are used well, the profit is very low, and the factory management is also very good. Only the profit is very low.
To choose a product, the protection of big brands only comes from the quality of the product, and it also has a lot to do with the after-sales service of its manufacturers. Jiangshanlai Electronics, professional cooling fan products, for more information, please consult our official website!
