Replacement CPU Cooling Fan

This is a new replacement CPU cooling fan for compatible laptops. It operates at DC 5 V with a rated power of 2.25 W. The unit uses a 4-pin connector for motherboard attachment. It is intended for owners who need to replace a worn or noisy original cooler.

4-Pin DC 5V Connector Compatibility

The single specification that decides fit is the 4-pin DC 5 V interface. The fan must match the exact part number EG50040S1-CL10-S9A or 5K20040FUV shown in the listing photos. Buyers who cannot verify this part number against their existing cooler will not achieve a working installation.

Direct Swap for Identical Part Numbers

The package contains one fan tested before shipping. It comfortably handles the thermal load of the original design when the part numbers align. It runs out where the connector pinout, voltage or physical mounting differ from the listed references. Buyers who need a universal cooler or a different voltage should not purchase this item.

Questions about this item

How much power does the 2.25 W fan draw when running in my laptop?

It draws 2.25 W at 5 V from the four-pin header, so the motherboard only needs to supply that amount for full speed.

What does the four-pin connector actually control on this cooler?

The fourth pin carries a PWM signal that lets the system vary the fan speed instead of running it at a fixed voltage.

What should I check to confirm this fan will physically fit my EG50040S1-CL10-S9A laptop?

Compare the mounting holes, cable length and overall shape in the photos with your original fan before ordering.
