220V Cooling Fan life depends on bearing life

"220V Cooling Fan" will primarily depend on the life of the bearing life, the life of the stator winding, three electronic component life. Bearing life depending on the design type and intensity of work between 1000 to 300,000 hours. Stator winding life in general use in normal environments up to hundreds of thousands, or even hundreds of more than one million hours; harsh environments, such as high temperature, low temperature, temperature, humidity, etc., it may significantly shorten. "220V Cooling Fan" electronic component life and longer life than the stator winding, but are vulnerable to environmental temperature, especially high temperature can significantly shorten the life of electronic components. According to the well-known flap (or bottlenecks) principle, the fan life determined by the shortest of the three bearing life. "220V Cooling Fan" of life will be affected by the work load: the higher the speed of the fan, the bearing wear sooner, the stator winding and the more heat the electronic components, shortening the life of the inevitable. This is the server's power needs in the field and did not mute the widespread adoption of temperature-controlled fan of reasons - to reduce the fan reasonable workload and prolong life.
