Internal Cooling Fan Assembly
The internal centrifugal fan uses a miniature bearing that is susceptible to lubricant migration and dust accumulation. Over time, this causes the impeller to oscillate, creating a high-pitched whirring or grinding noise as the blades make contact with the housing or vibrate out of sync. Replacing the entire fan module restores silent operation by providing a fresh bearing and clean impeller blades for laminar airflow.
