How to judge whether the cooling fan is refurbished

Cooling fans have always been a necessary cooling device for mechanical equipment that is prone to heat and high temperature. There are also many cooling fan manufacturers on the market, and some unscrupulous manufacturers have also purchased damaged second-hand cooling fans, refurbished them, and relaunched them on the market. This type of cooling fan sold after refurbishment is not only of poor quality and short service life, but also easily causes damage to other parts when damaged.
