Frequently Asked Questions

What is SUNON EG50040S1-CL40-S9A?
EG50040S1-CL40-S9A is a SUNON-branded laptop cooling fan listed for selected HP Pavilion laptop configurations. Commercial replacement listings identify it as a 5 VDC, 2.50 W fan with a four-wire, four-pin connector.

What is the rated voltage?
The listed rated voltage is 5 VDC. Confirm that the laptop's fan power supply and replacement assembly match this requirement before installation.

What are the rated current and power consumption?
Replacement listings specify 0.50 A and 2.50 W. These values are consistent with the calculation of 5 V multiplied by 0.50 A, which equals 2.50 W.

What connector does EG50040S1-CL40-S9A use?
The listed configuration uses a four-wire, four-pin connector. Exact pin assignments and wire colors have not been independently verified. Check the connector orientation and laptop wiring documentation before connecting the replacement fan.

Which HP laptop models are compatible?
Commercial replacement listings associate the fan with selected HP Pavilion 14-dv0000 and 14-ec0000 series configurations, including related 14Z-EC models. Compatibility depends on the exact laptop configuration, so confirm the existing fan part number before ordering.

What is the HP part number for this fan?
M24540-001 is a commonly listed HP part number for EG50040S1-CL40-S9A. Some replacement catalogs also list M34455-001. Verify the full part number against the installed fan and the laptop's service information.

Are DQ6D616M000 and ND75C39-20B04 compatible replacements?
These designations appear as related fan model references in third-party replacement listings. Their appearance in the same catalog does not independently establish that every version has the same connector, mounting geometry or electrical characteristics. Verify compatibility before substitution.

What are the dimensions of this fan?
A complete manufacturer dimensioned drawing for EG50040S1-CL40-S9A was not independently located. Check the installed fan's housing dimensions, mounting points, cable exit and air outlet against the replacement item.

What is the rated speed and airflow?
A verified RPM rating and airflow specification for the exact model were not independently located. Do not substitute performance values from another EG50040S1 variant without documentation confirming that the specifications apply.

Does this fan support PWM control or speed feedback?
The four-wire configuration is confirmed by replacement listings, but the exact PWM control specifications and tachometer signal characteristics were not independently verified. Confirm the electrical pinout and control requirements for the complete model before connecting it to the motherboard.

Is this a CPU fan or a GPU fan?
Some suppliers describe EG50040S1-CL40-S9A as a CPU cooling fan, while related listings identify it with integrated-graphics or UMA laptop configurations. The actual cooling position depends on the laptop's internal design. Confirm the installed fan's position and part number rather than relying only on a generic CPU or GPU description.

What should be checked before ordering?
Confirm the full model number EG50040S1-CL40-S9A, HP part number M24540-001 or the applicable documented replacement number, 5 VDC supply, 0.50 A current, 2.50 W power, four-wire connector, housing dimensions, mounting points and laptop configuration. If the existing fan label or connector differs, verify the replacement with the laptop's service documentation before purchase.
