How long is the manufacturer’s warranty for the life of conventional cooling fans

Conventional cooling fans are mainly divided into two categories from the bearing, one is an oil bearing, the other is a double ball bearing, the life of the cooling fan is mainly related to the bearing, of course, under the premise of stable reliability. In an environment with a normal temperature of 25 degrees and a humidity of 60%, the life of the double ball bearing cooling fan is 50,000 hours. This life is also the ball bearing given by the Japanese NMB company. The life of the oil bearing is 20,000 hours, which is also the life of the oil bearing. Of course, some manufacturers will advocate that oil-impregnated bearings can reach 30,000 hours, 40,000 hours, and they need to be used with caution. In fact, the use environment of the cooling fan we are talking about is often a high temperature and dusty environment, which has a significant impact on the life of the cooling fan. For example, high temperature, the life of the oil-bearing cooling fan will drop linearly. The higher the temperature, the shorter the life expectancy.
