In the selection process of the cooling fan, the manufacturer's technical strength, maintenance level, whether the after-sales service of the cooling fan is timely, and whether the normal use of the cooling fan can be guaranteed should also be considered. In addition, the performance of cooling fan manufacturers in the development of new products can reflect their technical strength and should also be included in the selection consideration.

   After the purpose of the cooling fan is determined, the grade of the cooling fan can be determined first according to the performance requirements of the cooling fan, and the decision is to choose a domestic cooling fan or an imported cooling fan. Then, it is necessary to have a basic understanding of a specific grade of cooling fan manufacturer, determine the production capacity, product quality, product specifications, product price and other information of the cooling fan manufacturer, and also consider the environmental protection level of the cooling fan.

   The selection of the cooling fan is a relatively complicated process and requires high technical requirements. There are also many ways to select the cooling fan, such as selection according to logarithmic coordinate curve, selection according to dimensionless characteristic curve, etc., and professional cooling fan selection software can also help us choose
