After using the 4010 cooling fan for a period of time, it is found that the noise is obviously greater than before. Is this due to the quality problem of the fan itself or other reasons?
Most of the reasons for this are the quality problems of the cooling fan itself. There is a cooling fan with oil-bearing structure. The bearing is made of copper powder metallurgy. The precision of the bearing itself is not high. At first, the sound is very quiet because of the addition of lubricating oil. Due to the effect of lubricating oil, the sound of rotating friction between the shaft core and the bearing is very small. With the extension of time, the lubricating oil becomes less Or dried up. The noise is getting louder and louder
The way to solve this problem is to use better quality bearings. The common method is to change the double ball bearing, which is recognized as a long life and useful structure for cooling fan manufacturers.
