Replacement CPU Cooling Fan

This DBTLAP fan replaces the Sunon EG50040S1-1C030-S9A unit used in compatible laptops. It runs on DC 5 V and draws 2.25 W of power. The K910B7 model is supplied as a single fan without additional mounting hardware. Buyers who need a complete cooling pad assembly with a base and multiple fans should look elsewhere.

Matching the EG50040S1-1C030-S9A Part Number

Compatibility depends on verifying that the original fan carries the exact EG50040S1-1C030-S9A marking. The supplier advises checking photographs and confirming the part number before ordering. Each unit is tested before it ships. Installers who cannot confirm the part number risk receiving a fan that will not fit.

Single Fan in the Package

The box contains only the 1x replacement fan itself. No screws, cables or thermal compound are included. The minimal bundle keeps the item lightweight for shipping but means the installer must reuse existing fixings. Technicians who expect a full installation kit will need to source those parts separately.

Questions about this item

What does the 2.25W rating mean once the fan is installed in a laptop?

The 2.25W rating shows the maximum power the fan draws from the laptop's 5V supply when running at full speed.

How does the DC5V interface affect compatibility with the SUNON EG50040S1-1C030-S9A part?

The fan requires a 5V DC header; it will only work in laptops wired for that exact voltage and connector.

What should I check to ensure the K910B7 fan physically fits my laptop?

Compare the photos and the EG50040S1-1C030-S9A part number against your original fan before ordering.
