Replacement CPU fan for LG 15N540 and 15ND540

This new DBTLAP cooling fan matches part numbers DFS561405FL0T and FFRN EAL61520801. It is built for LG 15N540 and 15ND540 laptops that need a direct 5V 0.5A replacement. The package contains one tested fan unit. Buyers who need a different voltage or connector layout cannot use this part.

Connector and mounting fit the original chassis

The fan uses the stock 5V 0.5A power interface so it plugs into the existing header without adapters. Mounting points line up with the factory screw locations on the LG 15N540 and 15ND540. Each unit is tested before shipping and photos show the exact item you will receive. Builders who want a higher airflow rating or a different form factor should look elsewhere.

Direct swap for a worn or noisy OEM cooler

This fan replaces the original LG cooler when bearings fail or noise becomes intrusive. The jump is worth it when the old part spins louder than the system load justifies or when thermal throttling appears. Verify the part number on your current fan against DFS561405FL0T and FFRN EAL61520801 before ordering. Users who need dual-fan assemblies or liquid-cooling upgrades will not be served by this single-fan module.

Questions about this item

What 5 V connector standard does the DFS561405FL0T fan use and what current draw does it cap at?

The fan plugs into the standard 5 V header on LG 15N540 and 15ND540 boards and is rated for .5 A, so the motherboard header limits the current to that value.

What physical dimensions and mounting pattern must match for the fan to fit the LG 15N540 chassis?

The replacement must match the original DFS561405FL0T housing, screw-hole spacing and cable length exactly; compare the product photos with your old fan before fitting.

How is the fan installed and which step do users most often get wrong?

Remove the old cooler, align the new fan’s screw holes with the 15N540 mounting posts, reconnect the 5 V .5 A header, then test — skipping the photo comparison step leads to ordering the wrong part number.
