Replacement Fan for SUNON EG50040S1-CT90-S9A

This new DBTLAP cooling fan is a direct replacement for the SUNON EG50040S1-CT90-S9A model with part number N18899-001. It operates on a 5V power supply and is designed to restore cooling performance in compatible laptops. The package includes one fan unit that has been tested before shipping. Buyers should verify the part number and photos against their original component before ordering.

Integration Into a Laptop Cooling Assembly

The fan slots into the existing thermal module where the original SUNON unit was mounted, drawing power from the laptop's 5V fan header. No additional cables, controllers or mounting hardware are supplied, so the original screws and connectors must be reused. Correct part-number matching frees the builder from trial-and-error fitting and ensures the cooling system functions as intended.

Suitable for Targeted Repairs.

This part suits technicians and owners replacing a failed or noisy fan in a laptop that uses the exact SUNON EG50040S1-CT90-S9A model. It is not suitable for builders seeking a generic cooling pad, a higher-airflow upgrade or a fan with a different voltage, connector or form factor. Buyers without the matching part number should look elsewhere.

Questions about this item

How long does the SUNON EG50040S1-CT90-S9A fan maintain its rated 5V airflow before thermal throttling reduces speed?

The fan is tested before shipping and designed to run continuously at 5V; sustained operation stays within its thermal envelope because it replaces the original OEM cooler directly.

What noise level and heat output should I expect when this 5V replacement fan runs all day in a laptop chassis?

As a direct SUNON EG50040S1-CT90-S9A match, it produces the same acoustic and thermal profile as the factory fan — quiet enough for office use and no hotter than the original design.

You need a laptop that originally uses the SUNON EG50040S1-CT90-S9A (PN N18899-001) — verify your service manual or the photos to confirm the 5V connector and screw pattern match.
