How to identify whether the newly-bought cooling fan is new rather than refurbished?

Back to list Release date: Dec 17, 2018

        cooling fan has a wide range of applications.customers may encounter fake products and refurbished second-hand goods when buying cooling fans, thus greatly affecting their use. So, when we buy it, if we screen whether it is refurbished or not?


        First of all, judging from the trademark:generally speaking, the trademark of the original cooling fan of the genuine brand has its own anti-counterfeiting mark, which can be inquired by the customer service of the brand, and then compared.generally speaking, the renovated trademark is irregular and the printing quality is very poor, often the background color will vary in depth and the handwriting will not show any sense, and a few strokes with fingernails will scrape the color off the surface of the trademark, while the original trademark will not be affected by fingernail scraping.


        Secondly, judging from the fan blades:the fan blade surface of the original cooling fan will show a matte effect, and fine and uniform particles can be seen in the light and feel rough by hand; However, due to the long-term friction with the air, the particles on the surface of the fan blades have disappeared and become smooth, and the marks of rubbing can be seen.


        The last thing is to look at the fan mounting holes.All the renovated fans have been used, so marks will be left on the mounting holes.If they are fixed with self-tapping screws, threads will be left in the holes, and if they are fixed with screws and nuts, marks of nuts will be left around the holes.


        In addition, if you bought it from an agent or dealer, ask the merchant about the purchase channel.
