The most obvious difference is the difference between the material and the bearing, and the price will vary greatly. In addition, the standard of each manufacturer is different. Good manufacturers have strict technical requirements, and the cost will also increase. Therefore, these are the price differences Therefore, it is better not to choose the fan manufacturer of Shanzhai when choosing chassis fan. Let's take a look at how to select chassis fan.

1. First confirm the size of the chassis, select the model and appearance, and then determine the parameters such as voltage, air volume, speed, current, noise, etc.

2. Confirm the service life of the fan in the case. The service life of hydraulic pressure is about 20000 hours, oil-bearing 30000 hours and ball bearing 60000 hours.

3. The quality of the stator and copper wire affects the quality of the chassis fan, and the good copper wire and stator improve the speed, directly affect the use time of the chassis.
