Radiator development has been accompanied by two themes -- heat and quiet. To improve the heat radiating performance, the most simple way is to increase the speed of the fan, the fan speed increases after the noise is followed by larger. Then the noise from two aspects, one is the fan air cutting roar, on the other hand, is a fan of mechanical equipment friction sound, the sound is sent out of the bearing. Some of the quality of the radiator, often caused by the use of the fan is poor, if you buy that product.
Thus, as an important part of the fan bearing how important it is for our radiator, the more common these fan bearing products on the market, we work together to have a look:
1, oil bearing SleeveBearing
Oil bearing SleeveBearing: this kind of bearing can be said to be bearing technology is now on the market are older, but because of low cost, easy to implement in technology, many products including well-known brands are still continue to use, the utility model has the advantages is the initial use of quiet, low noise, low price; but in general to the later due to the internal oil the volatile and dust, causing serious wear on the bearings, resulting in slow speed, noise increases, the average life of only 8000~15000 hours.
