For customers who have ultra-thin cooling fans below 10mm, it is believed that after more or less the cooling fan has been used for a period of time, there will be noises and abnormal noises of different ranges. It is still very quiet at the beginning. The use time increases, the noise becomes louder and louder, and the grunting sound becomes louder and louder. Why does this happen to the cooling fan?
Ultra-thin cooling fan such as 3007, thickness is 7mm, 90% of manufacturers supply oil bearing or hydraulic structure, the material of this bearing is pressed by copper powder, the precision is poor, but because of Lubricating grease is added between the bearing and the shaft core, so the shaft core will not directly touch the bearing to produce a grunting sound when it starts running. When the cooling fan is used, high temperature and dusty environment will accelerate the volatilization of oil. When the oil dries, the dust will be sucked into the bearing. At this time, the noise will come out. There is no way to avoid it.
Jingyangda Technology aims at ultra-thin cooling fans, imported high-precision double ball bearings from Japan, with strong high temperature resistance and strong dust-proof function, which is more than twice the life of oil-impregnated bearings. It is mainly for instruments. For equipment, industrial products and other products that work continuously for 24 hours, the cooling fan can ensure no noise for 3 years.
