When we choose a cooling fan, the first thing we must consider is the service life. How long can it be used? Then what factors do the service life 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.
Mainly the fan with oil-containing structure.
