Left Cooling Fan Module
The vibration is caused by bearing eccentricity or a blade imbalance within the centrifugal fan assembly. Over time, the internal lubricant in the fluid dynamic bearing degrades or the sleeve wears down, allowing the impeller to wobble during high-speed rotation. This wobble creates mechanical resonance that transfers through the chassis, requiring a full module replacement as the assembly is factory-sealed.
