Is the noise of the double ball cooling fan smaller than that of the oil-containing type?

The level of noise has always been the most discussed topic of cooling fans. Some customers’ products have high requirements on the sound of cooling fans, such as vehicles, communication equipment, smart wearables, medical equipment, industrial equipment, smart homes, and other products. Customers will ask double Is the ball-bearing cooling fan less noisy than the oil-containing type? We need to understand the situation. For the same fan and the same mold, apart from the abnormal bad sound, the noise we call is wind noise, which is related to the speed of the cooling fan. The higher the speed, the greater the noise. , This has nothing to do with the bearing. Why is there a saying that the double-ball bearing cooling fan has less noise than the oil-contained cooling fan? Perhaps it is because the double-ball bearing cooling fan maintains better noise stability, and the oil-contained cooling fan Affected by high temperature, dust and other factors, it is generally difficult to ensure that the noise will not increase within one year. As the oil volume of oil-bearing bearings decreases, the noise is getting louder and louder. The noise of double ball bearings generally does not change much within 3 years, and many electronic products are only guaranteed for one year, up to three years, and there will be almost no problems reflecting the noise of the cooling fan, especially for cooling fan manufacturers in Japan. Imported ball bearings, life and sound are more guaranteed. Welcome to visit the cooling class and news center of the cooling fan manufacturer again.
