How to deal with the noise of the cooling fan? Many customers will have such problems, especially the oil-bearing. After using for a period of time, the noise becomes more and more serious. So how to deal with the noisy cooling fan?
1. When used in high temperature environment, the oil in the cooling fan bearing dries up and loses lubrication, so the friction coefficient is big and the noise becomes more and more loud. Therefore, it is recommended to select the oil bearing for the ambient temperature of 0 to 75 degrees, and the cooling fan with double ball bearing for the temperature from 75 to 130 degrees and from 0 to 30 degrees below, which will also reduce the noise.
2. Impurity dust and other problems affect the noise of the fan. It is recommended to select metal dust-proof net cover to reduce dust and foreign matters entering, clean well, avoid blocking the fan outlet or air inlet, and also reduce the fan noise.
