There is a big difference between the good and bad of the cooling fan and the material above. The good material directly determines the life, performance, stability and so on of the cooling fan. 1. The outer frame is made of PBT material with high temperature resistance, the price is more economical, aluminum Alloy shock-proof, high temperature resistance, not easy to deformation, better cooling effect. 2. The blades are made of aluminum alloy, high strength, not easy to deform, not easy to fall off, strong wind, low noise, corrosion resistant, not easy to rust, not stained with dust, smooth operation, 3. The coil is made of brand new pure copper, lower the operating temperature and current of the fan, more energy-saving and environmental protection, 4. PCB Board, original chip, capacitor and Glass Fiber Board make the fan less power consumption and more stable performance 5. Bearing, double Ball bearings are much more durable than oil bearing the above is a brief introduction to the material difference of the cooling fan in Dongxingyue, a good cooling fan is very important, not only can make the normal operation of equipment, also can extend its service life, the work efficiency also increases, if you want to know more radiator fan knowledge can pay attention to us.
