The cooling fans rotor-flabellum.
The cooling fans rotor components: Shaft / fan / motor housings / plastic magnetic;
Often the number blades of the cooling fans: The fan blades are mostly 7,9,11 other odd number, even if the use of blades, it is easy to make the system resonance, will make the blade or shaft fracture;
cooling fan rotor
About the Blade Balance: the physical centroid of the blade axis is not the same shaft, fan blades in operation will cause imbalance, the vibration.
