Replacement fan for EG50040S1-CE01-S9A

This 5 V, 2.25 W cooling fan is built to fit the EG50040S1-CE01-S9A and DC28000DUS1 laptop models. It serves owners who need a direct swap for a worn or noisy original unit. The 4-pin connector matches the motherboard header for speed control and monitoring. Each unit is tested before shipping to confirm operation.

Four-pin PWM connector and tested build

The 4-pin interface allows the system to adjust fan speed automatically based on temperature. A precise match to the original dimensions and mounting points means no modifications are required during installation. Real-item photographs let buyers verify the housing and cable routing before purchase. The package contains only the fan itself.

Upgrade from a failing stock cooler

This part replaces a factory fan that has become loud, slow or has stopped spinning entirely. The jump is worth it when thermal throttling appears or the original bearing noise becomes distracting. It is not suited for users seeking higher airflow than the original design or for laptops using a different part number. Compatibility must be confirmed against the listed model numbers.

Questions about this item

What 4-pin interface does the DC28000DUS1 fan use, and what voltage does it cap at?

The fan connects via a 4-pin header and runs on a 5 V supply, drawing 2.25 W at full speed.

What physical dimensions must the laptop chassis accommodate for the EG50040S1-CE01-S9A fan to fit?

The replacement fan is built to match the original EG50040S1-CE01-S9A form factor, so it fits the same mounting holes and screw positions as the factory unit.

How is the fan installed, and which step do people often get wrong?

Disconnect the battery, remove the old fan, align the 4-pin connector carefully, secure the screws, then reconnect the battery — reversing the connector orientation is the common mistake.
