Replacement fan for SUNON EG50040S1-CI42-S9A

This new laptop CPU cooling fan matches the SUNON EG50040S1-CI42-S9A part number and the DC28000ONSL 0WX28K reference. It is intended for owners repairing a laptop that uses this exact fan model. The package includes one tested fan unit. Buyers who need a complete cooling assembly with heatsink or mounting brackets will not find those parts here.

Installation fit and compatibility

The fan slots into the laptop's existing cooling cavity and connects to the motherboard header used by the original SUNON unit. Correct part-number alignment frees you from modifying brackets or rewiring connectors. Each unit is tested before shipping to confirm it spins up properly. Installers who cannot verify the part number against their current fan risk ordering a unit that does not fit.

Cooling capacity and limits

Designed to the original SUNON specification, this fan delivers the airflow the laptop's thermal solution expects for the CPU. It handles the heat load the factory cooling system was built to manage. The fan alone does not increase the thermal ceiling beyond the laptop's original design. Systems with degraded heatsinks or dried thermal compound may still run hot after the swap.
