Legion 5 Replacement CPU and GPU Cooling Fan Set
Loud noise in high-performance laptops is most frequently caused by the failure of the fluid dynamic bearings or dust-induced imbalance in the fan blades. Replacing the dual-fan assembly eliminates mechanical grinding, rattling, or high-pitched whining caused by physical wear. This is the most effective solution for hardware-level noise issues.

High-Performance Thermal Interface Material (PTM7950 or Thermal Paste)
If the fan is loud due to high RPMs at idle (as reported in source data), the root cause is often poor thermal conductivity between the silicon and the heatsink. Applying high-grade thermal compound reduces operating temperatures, allowing the system's BIOS/firmware to maintain a lower, quieter fan curve.

Compressed Air Duster
Accumulated dust in the high-density cooling fins of the Legion 5 creates air resistance and turbulence, which manifests as increased 'whooshing' or 'jet engine' noise. Clearing the intake and exhaust pathways restores laminar airflow and reduces the thermal load that triggers high-speed fan operation.
