Clear noise edit
First, lubricated bearings "Micro Cooling Fan" transport the most important parts is bearing a long time the lack of oil, will generate noise such high-speed rotation. Therefore, we only need a few drops on the fan bearing lubricant, sewing machine if you do not use can be replaced. But be careful do not use oil instead, because of its relatively large particles, easy to damage the bearings.
Second, the fixed blade vibration noise is also an important part of the fan noise, because the leaves loose in the bearing and bearing wear resulting in the gap becomes larger and so on, so only need to remove the sub-sector, the screws tight button, so firmly fixed After that, there will be no shock.
Third, the use of poor quality polished blades additional cooling fan, in the production of this type of fan due to defects in workmanship, the center of gravity may not be in the blades on the axis, the formation of "eccentric" and use over time, "Micro Cooling Fan" in "eccentric" phenomenon will become more serious, it will not only produce noise, serious damage may also CPU. In this regard, can be removed altogether, and then thread hanging from its center position, let it sink still to see which direction to put an end to sink in light grinding wheel a few times, and then tested, has been be "Micro Cooling Fan" in a horizontal position and then later be able to install up to.
