When we choose a cooling fan, we must consider the life span and how long it can be used. Then what factors do the life span of the cooling fan depend on? The main factor is the bearing, then the ambient temperature, and the balance of the fan blade.
Bearing: The life of the double ball bearing is nominally 50,000 hours, and the life of the oil-impregnated bearing is nominally 3 hours (under normal temperature)
2. Ambient temperature: the higher the temperature, the shorter the life span, especially the oil-bearing cooling fan, which is particularly sensitive to high temperature
3. The balance of the fan blades: the fan blades are poorly balanced, and shake badly. After a long period of time, noise appears first, and then it may be stuck.
Although Chengda Electronic Technology has done its best to make the fan blades more balanced when designing the mold, if the fan blades still shake during operation, we have a high-precision dynamic balancing machine to correct and repair, so that the fan blades can run more. Stable and longer life span, which is ignored by many cooling fan factories
