Replacement heatsink fan for XPS 13 9300

This new DBTLAP heatsink fan replaces the original cooling assembly in Dell XPS 13 9300 laptops. It matches part numbers EG50040S1-CI30-S9A, EG50040S1-CI42-S9A, DC28000ONSL, AT2SZ004SSL, 0G4WF7, G4WF7 and 0WX28K. The package includes one tested fan unit. Buyers who need a complete cooling module with heatpipes should look elsewhere.

Thermals noise and power draw

The fan operates at 5 volts and draws 0.27 amps, a low-power profile suited to the ultrabook chassis. As a direct replacement it restores the factory airflow and acoustic profile without adding extra noise. Each unit is tested before shipping to confirm correct spin-up and RPM behaviour.

Critical compatibility check

You must verify the part number on your existing fan against the list above before ordering; the XPS 13 9300 uses more than one fan variant and only the exact match guarantees fitment. No other specification determines whether this is the right part.

Questions about this item

How do I install the DBTLAP heatsink fan in my Dell XPS 13 9300 and which step is commonly missed?

Remove the bottom cover, disconnect the old fan cable, swap the unit, reconnect the 5V 0.27A plug, then replace the cover; the step often missed is verifying the part number matches EG50040S1-CI30-S9A or EG50040S1-CI42-S9A before fitting.

What maintenance or replacement will this cooling fan need over time?

The fan is a single moving part rated at 5V 0.27A; expect to clean dust from the heatsink fins periodically and replace the whole unit if bearing noise appears or airflow drops.

What limit appears first when the fan runs continuously under heavy load?

The 5V 0.27A power envelope caps maximum speed, so sustained heavy loads hit the current limit before thermal headroom is exhausted.
