Ruth's sister Internal Power Cable for Laptop

This internal power cable is designed to connect a DC 5V 0.40A cooling fan inside compatible laptops. It serves as a replacement part for models E7420, E7440 and E7450. The component is supplied new and matches the original manufacturer specification. Builders repairing or maintaining these specific systems will find it a direct fit.

Sustained Operation and Thermal Reliability

Under continuous load the cable delivers stable 5V power to the cooler fan, maintaining consistent airflow over the CPU. It avoids voltage drop that could reduce fan speed during extended sessions. The part is not suited for higher-voltage fans or desktop power supplies. Buyers needing multi-fan harnesses or desktop ATX connectors should look elsewhere.
