Replacement CPU Cooling Fan

This replacement fan fits laptops that use the EG50040S1-CL00-S9A part number. It operates at 5 V DC and draws 2.25 W through a standard 4-pin connector. The unit is supplied new and individually tested before dispatch. It is intended for owners who need a direct swap for a worn or noisy original cooler.

Upgrade From a Failing Original

The fan replaces an existing cooler that has become loud, spins unevenly or has stopped completely. A swap is worthwhile when the laptop throttles under load or shuts down from overheating. If the current fan still runs quietly and maintains stable temperatures, the change offers no benefit. Buyers who want additional cooling beyond the factory design should look elsewhere.

Cooling Capacity and Limits

The 2.25 W motor provides airflow equivalent to the stock specification for compatible models. It handles typical office workloads, web browsing and video playback without thermal throttling. Sustained heavy tasks such as compiling code or rendering video may push the laptop beyond what this single fan can dissipate. Systems that require higher airflow or dual-fan arrangements are not served by this part.
