Frequently Asked Questions

What is SUNON EG70050S1-1C040-S9A?
EG70050S1-1C040-S9A is a SUNON DC laptop cooling blower commonly identified as a CPU cooling fan in replacement listings for Lenovo Yoga C940-15IRH and related laptop cooling assemblies.

What is the rated voltage of EG70050S1-1C040-S9A?
Multiple exact-model replacement listings specify 5 VDC. The fan should be connected only to a compatible laptop fan power and control interface.

What is the rated current?
Exact-model replacement suppliers specify 0.50 A. An independently published SUNON electrical specification for this complete suffix was not located.

What is the power consumption?
Multiplying the listed 5 VDC supply by 0.50 A gives a calculated electrical power of 2.50 W. This is a calculated value, not a separately verified SUNON rated power specification.

Is EG70050S1-1C040-S9A an axial fan or a centrifugal blower?
It is used as a shrouded laptop cooling blower with directed airflow through the equipment's cooling assembly. Its mounting arrangement differs from that of a standard square-frame axial fan.

What are the external dimensions?
An exact-model dimensioned manufacturer drawing was not independently located. Compare the existing blower's overall length, width, thickness, mounting positions and exhaust outlet before ordering.

What is the rated fan speed?
A reliable SUNON RPM rating for EG70050S1-1C040-S9A was not independently established. Generic cooling-kit speed figures should not be assigned to the individual fan without model-specific verification.

What is the airflow or static pressure rating?
An exact-model SUNON airflow curve, CFM rating and maximum static pressure specification were not independently located. Cooling performance should be confirmed using the applicable equipment service documentation or manufacturer information.

What bearing system does EG70050S1-1C040-S9A use?
A manufacturer bearing specification for the exact fan model was not independently verified. Bearing descriptions from combined CPU/GPU replacement kits should not automatically be assigned to the individual fan.

How many wires and connector pins does the fan use?
Commercial listings specify four wires and a four-pin connector. The exact electrical pinout, connector pitch and control-signal assignments were not independently verified, so they should be matched against the existing part.

Which laptops are compatible with EG70050S1-1C040-S9A?
Replacement cooling assemblies list Lenovo Yoga C940-15IRH, machine type 81TE, and Lenovo Yoga 9-15IMH5, machine type 82DE. Compatibility depends on the individual machine configuration and installed thermal module. Lenovo 5H40S19977 identifies a related cooling assembly rather than proving that every individual fan is interchangeable.

What should be checked before ordering EG70050S1-1C040-S9A?
Confirm the complete SUNON EG70050S1-1C040-S9A model number, 5 VDC supply, 0.50 A current rating, four-wire connection, four-pin connector, wire order, blower housing shape, mounting positions, cable length, exhaust direction and laptop machine type. Distinguish the CPU-side 1C040-S9A fan from the related EG70050S1-1C030-S9A GPU-side fan. Also verify whether the required replacement is a single blower, a matched CPU/GPU fan pair or a complete fan-and-heatsink assembly. Compare the existing part and consult the applicable Lenovo hardware maintenance instructions before installation.
