The oil leakage of the cooling fan will increase the friction of the bearing, which will lead to an increase in temperature, an increase in the expansion coefficient, and a locked fan blade.

Long-term friction consumption of the bearing alloy will make the gap larger, cause jitter, and generate noise.

At present, there is no way to eliminate it, and the way to improve is to use turbine oil correctly.

However, refueling the cooling fan again can only serve as a relief. It is recommended to replace the cooling fan.
