Internal Cooling Fan Assembly
The grinding noise is a hallmark of bearing failure or blade-to-shroud interference. Over time, the lubricant within the fan motor dissipates or becomes contaminated, causing the impeller shaft to wobble during high-speed rotation. This eccentricity leads to the fan blades striking the internal housing, creating a mechanical grinding sound that cannot be resolved through cleaning or software updates.
