EG50050S1-CE90-S9A 4-pin replacement fan

This is a 4-pin DC 5 V 0.40 A cooling fan built for the EG50050S1-CE90-S9A laptop cooler. It arrives new and includes one fan unit. The part is identified by DPN 040DHH and is tested before shipping. Photographs show the exact item you will receive.

Owners of the matching cooler needing a direct swap

This suits anyone whose original EG50050S1-CE90-S9A fan has failed and who can confirm the part number and connector match. It will not fit coolers that use a different voltage, pin count or mounting layout. Buyers who cannot verify the model number should look at other options.

4-pin DC 5 V 0.40 A electrical interface

The decisive specification is the 4-pin DC 5 V 0.40 A power interface. Only coolers designed for this exact voltage, current and connector will work with the fan. Match the DPN 040DHH and the photographs to your original part before ordering.

Questions about this item

Does the 4-pin DC5V 0.40A interface limit fan speed control to PWM only?

The 4-pin connector supplies 5 V at 0.40 A and carries a PWM signal, so the motherboard can vary speed through duty-cycle changes rather than voltage alone.

What physical clearance does the EG50050S1-CE90-S9A fan need inside the laptop chassis?

The replacement fan matches the original DPN:040DHH form factor; verify the mounting holes and cable routing against the photos before fitting it into the existing cut-out.

Which step do installers most often miss when fitting this 4-pin cooling fan?

Many forget to peel the protective film off the bearing sticker and to seat the connector key fully into the 4-pin header before tightening the screws.
