Replacement fan for Dell Latitude 7400 2-in-1

This new cooling fan is built specifically for the Dell Latitude 7400 2-in-1 laptop. It matches the original part numbers EG50040S1-1C260-S9A and DC28000PQS0. The unit is intended for owners who need to replace a worn or noisy internal cooler. Buyers with a different Latitude model or a standard clamshell chassis cannot use this part.

Tested thermal component for quiet operation

Every fan is tested before shipping to confirm it spins correctly and moves air through the heatsink. Proper airflow keeps the processor at safe temperatures during normal workloads. A functioning cooler also prevents the system from throttling performance due to heat. Installers should verify the connector orientation before securing the screws.

Direct-fit design with single connector

The package contains only the fan assembly; no extra brackets or cables are included. Mounting holes align with the existing screw points on the 7400 2-in-1 motherboard tray. Photographs of the original cooler should be compared to the listing images to confirm a match. If the part number differs, the fan will not fit the chassis.

Questions about this item

How do I install the WG4KN fan in my Dell Latitude 7400 2-in-1?

Power off the laptop, remove the bottom cover, disconnect the old fan cable, swap the unit, reconnect the cable, and refit the cover; the step often missed is verifying the part number matches EG50040S1-1C260-S9A or DC28000PQS0 before fitting

What maintenance will this cooling fan need over time?

The fan is a single moving part; expect to clean dust from the heatsink fins periodically and replace the unit if bearing noise appears or airflow drops

What limit appears first when the WG4KN runs under sustained load?

The small internal fan reaches its maximum RPM and thermal ceiling before the larger chassis can dissipate heat, so sustained loads hit the fan's airflow limit first
