About what the life of a cooling fan?
1. Bearing: double ball bearing life span of the nominal 50000 hours, the service life of oil bearing nominal (3 hours At room temperature under normal)
2. The environment temperature, the higher the temperature, the shorter the life, especially the oil bearing type cooling fan, particularly sensitive to high temperature
3. Blades balance: blades balance is poor, shaking, noise in the long run is first introduced, then may be card death turned
JingYang although science and technology in the mold design, has made blades more balance as much as possible, if, when running blades or jitter, we have high precision dynamic balancing machine to be more positive, repair, take the blades run more smoothly, longer life, this is a lot of cooling fan factories are ignored
