Vszerda Cooling Fan for ThinkBook 13-inch Series

This replacement fan cools both the CPU and GPU in select ThinkBook 13s-IWL, 13s-IML, K3-IWL and S540-13IWL laptops. It arrives new and includes the complete fan assembly ready for installation. The part matches OEM numbers DFS5K123043630, FLDU, DFS150305140T and FL03. Verify the part number and photos before fitting.

Who This Suits and Who Should Look Elsewhere

This suits technicians repairing a listed ThinkBook 13-inch model with a noisy or failed cooler. It is not for owners of other laptop series, larger 15-inch chassis, or desktop systems. Buyers who need a single CPU-only fan or a different connector layout should look elsewhere.

Critical Specification: OEM Part Numbers

The decisive factor is an exact match to part numbers DFS5K123043630, FLDU, DFS150305140T or FL03. Only laptops carrying one of these codes will accept the connector, mounting holes and airflow profile. Cross-reference the sticker on the original fan before ordering.
