Believe that many customers will ask the seller when consulting a cooling fan is manufacturer, generally there are two causes, first, manufacturers selling a cooling fan is definitely cheaper than traders; Second, manufacturers selling fan is original, is not a refurbished machine. Tong chi car has research and development, production experience, a cooling fan manufacturers, now here to explain how the difference between a refurbished fan and the original fan, for the vast number of customers to be a reference when purchasing a cooling fan.
can have a look at the brand first: original cooling fan's trademark printing is very fine, uniform color, printing clear luster, and a protruding sense; Fan of the trademark for the retrofit is informal, print quality is very poor, often will color shades, handwriting and no protruding, and gently with fingernails scraping a few trademark surface will scrape your colors, and the original trademark hand fingernails will not be affected.
the second view blades: the original surface of the cooling fan fan blades can present an inferior smooth effect, to light can see the fine and uniform particles, with the hand touch feeling is rough; Fan because of long time and air friction, the retrofit particles on the surface of the blade all have no, smooth, can see use scratch marks.
end and mounting holes: renovation fan is used, so will leave a mark on the mounting holes, if it is to use the work will be left in hole thread on the screw, if it's with screws and nuts will be around the hole of the indentation left nut.
