In customer demand to buyCooling fanAt the same time, I believe many customers will ask whether the seller is a powerful manufacturer for two reasons. First, the cooling fan sold directly by the manufacturer is definitely cheaper than that of the agent. Second, the fan sold by the manufacturer is original and will not be a refurbished machine. Shenzhen Jiangshanlai Electronic Technology Co., Ltd. is a cooling fan manufacturer with 16 years of research and development and production experience. It has been deeply engaged in the industry for 16 years. Xiao Bian is here to explain how to distinguish the refurbished fan from the original fan, so as to give you a reference when purchasing the cooling fan and let you not step on the thunder!
First of all, you can look at the trademark when purchasing: the trademark printing of the original cooling fan is very exquisite, the color is uniform, the printed handwriting is clear and glossy, and there is a sense of protrusion; However, because the trademark of the refurbished fan is irregular and the printing quality is very poor, the background color will be different, and the handwriting will not have a sense of protrusion, the original trademark will not be affected by fingernail scraping.
Then look at the fan blades: for the original cooling fan, the surface of the fan blades will present a matte effect, and fine and uniform particles can be seen facing the light, which feels rough by hand. However, due to long-term friction with air, the particles on the surface of the fan blades are gone and become smooth, and traces of rubbing can be seen.
Finally, there are mounting holes: the refurbished fans are all used, so traces will be left on the mounting holes. If they are fixed with screws, they will leave threads in the holes. If they are fixed with screws and nuts, they will leave nut indentations around the holes.
