We buy DC fans will be tested for its good or bad, for the first time to use the fan how to test good or bad?

 A good cooling fan is not only good at the beginning of the test, but also good at the cooling effect after a long time. By comparing the parameters of the cooling fan, power, air volume, air pressure and noise, the same speed wind voltage selection power is small, meaning that the power consumption is small, the same speed noise less fan will be better, compared to test the ability of technical staff, the better shape of the fan blade design, the greater the wind volume. 

The above is a brief introduction on how to test the quality of DC fans. I hope it can help you. Dongxing Yue has 12 years of experience in the industry.
