Examples of ways to maintain DC cooling fans
A general DC cooling fan has a lifespan of up to 40,000-60000 hours under normal use, and its lifespan will be reduced under unsuitable temperatures and environments. It needs to be maintained on time to reach the normal level. The DC cooling fan is stored and maintained in a correct way to extend the service life of the DC cooling fan.
