Replacement fan for SUNON EG50050S1-CJ90-S9A

This DBTLAP cooling fan is a direct replacement for the SUNON EG50050S1-CJ90-S9A unit used in compatible laptops. It operates on DC5V power and matches the original DC28000YBS0 and CN-0005GP part numbers. The package includes one tested fan. Buyers must verify their exact part number against the photos to ensure fit.

Thermals noise and power draw

The fan runs on a 5 V supply and spins at 28000 RPM to move air through the laptop heatsink. Normal operation keeps component temperatures lower than a passive heatsink alone. Noise level is typical for a high-speed 5 V blower in a thin chassis. Power draw stays within the USB-style 5 V rail limits of the host notebook.

Sustained load behaviour

Under continuous load the fan maintains its 28000 RPM rating to sustain airflow. The bearing and motor are tested before shipping to handle extended duty cycles. Thermal throttling in the laptop is reduced compared to a worn or failed original fan. Users who need higher static pressure or lower acoustic output should look for a different cooling solution.

Questions about this item

How do I install the SUNON EG50050S1-CJ90-S9A fan in my laptop?

Power off the laptop, disconnect the battery, open the chassis, unplug the old fan, match the connector to the DC5V header, secure the new fan, reassemble, then test before closing the case fully.

What maintenance will this DC5V cooling fan need over time?

Clean dust from the blades and vents every few months with compressed air; if bearing noise appears or airflow drops, replace the fan unit as it is not serviceable.

What limit appears first when the fan runs continuously at 28000 RPM?

Bearing wear and heat buildup in the motor windings are the first limits during sustained operation at the rated 28000 RPM speed.
