"220V Cooling Fan" transport is the most important part 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, do not use the machine if the machine can also be replaced. But be careful do not use cooking oil instead, because of its relatively large particles, easy to damage the bearings. Vibration noise is also an important part of the fan noise, because loose blade on the bearing and bearing wear cause big gap, etc, and therefore only need to remove the sub-sector, the screws tight button, after so firmly fixed, it will not then shake.
