Replacement Cooling Fan for Lenovo S550

This replacement cooling fan is built for the Lenovo S550 laptop and carries part number EG50040S1-1C040-S9A. It runs on 5 V DC power and draws 2.25 W through a four-pin connector. The unit is supplied new and each one is tested before it leaves the supplier.

Who this suits and who it does not

The fan suits owners of a Lenovo S550 who need to swap out a worn or noisy original cooler. It is not for anyone whose laptop uses a different part number or a different connector layout. Buyers who want a complete cooling pad with an external frame should look at a different product type.

Deciding specification: four-pin connector

The four-pin connector and 2.25 W power rating are the figures that confirm whether this fan matches the motherboard header in your S550. Check the photos and your old fan’s label to verify the part number matches exactly. If the connector or wattage differs, the fan will not fit or work correctly.
