Internal Cooling Fan Assembly
The most common cause of 'loud' or 'grinding' noise is the failure of the fan bearings. Over time, the lubricant inside the bearing housing dries out or is contaminated by dust, leading to shaft instability and vibration against the fan shroud. Replacing the entire fan assembly is the only permanent solution to restore quiet operation.

High-Performance Thermal Grease
If the fan is loud due to constant high-velocity airflow (max RPM), it is often caused by dried-out thermal interface material (TIM) between the CPU and heatsink. Replacing the factory paste with high-conductivity grease reduces the thermal load, allowing the system controller to throttle the fan to lower, quieter speeds.

Compressed Air Duster
Accumulated dust in the heat exchanger fins and on the fan blades creates turbulence and forces the motor to work harder against resistance. Cleaning the airflow path removes obstructions that cause 'whooshing' or whistling noises and prevents the fan from spinning at unnecessarily high frequencies.
