The Influence Of Bearings On The Lifespan Of Heat Dissipation Fans

When users choose a cooling fan, they always hope for a longer lifespan as long as the air volume is met. Of course, the lifespan of the cooling fan is related to the bearings used, the operating environment temperature of the cooling fan, and the balance of the fan blades.
1. Cooling fan uses bearings: Double ball bearings are used, which are relatively high-end bearings with a long service life ranging from 50000-100000h. Using oil bearing, the service life of oil bearing is about 10000 hours. Using hydraulic bearings, it has a larger oil storage space than oil bearings and a service life of around 40000 hours. The selection of bearings accounts for a significant proportion of the lifespan of the cooling fan, as they operate at room temperature.
2. Operating environment temperature of the cooling fan: When the cooling fan is running, the higher the ambient temperature, the easier it is to reduce its lifespan.
3. The poor balance of the cooling fan blades can cause the cooling fan to vibrate. Prolonged vibration time can increase noise, cause weight loss, and then the fan may directly become stuck.
