Replacement CPU cooling fan for SUNON

This new DBTLAP fan matches the SUNON EG50040S1-CI42-S9A DC28000ONSL 0WX28K specification. It operates at 5 V and draws 0.27 A. The unit is intended for laptop owners replacing a failed or noisy original cooler. Buyers who need a complete cooling pad with multiple fans should look elsewhere.

Electrical and compatibility limits

The fan runs on a 5 V DC supply with a 0.27 A current rating. Compatibility depends on an exact match to the SUNON part number and connector. Systems requiring a different voltage, pinout or form factor cannot use this part.

Build and installation notes

Each fan is tested before shipping and arrives as a single unit without mounting hardware. The connector and screw positions must align with the original assembly. Verifying the part number against the old fan is essential before fitting.

Questions about this item

How do I choose the correct fan version for my laptop?

Match the part number EG50040S1-CI42-S9A and the label DC28000ONSL 0WX28K exactly to your original fan; the photos show the connector and mounting layout for visual confirmation.

What does the 5 V 0.27 A rating mean once the fan is installed?

It draws 0.27 A at 5 V, so the laptop’s fan header must supply at least that current; the 28000 RPM maximum speed is reached only when the controller provides full voltage.

Which interface does the fan use and what does it limit in practice?

The fan connects via the standard laptop PWM header; the 5 V supply caps the top speed at 28000 RPM and the 0.27 A draw limits how much current the motherboard must deliver.
