Direct Replacement Cooling Fan

This DBTLAP laptop cooling fan is a direct replacement for the SUNON EG50050S1-1C050-S9A model. It is designed for repair technicians and owners who need to restore original airflow in a compatible notebook. The unit operates on a 5V supply and draws 2.50W through a 4Pin connector. Each fan is tested before shipping to confirm function.

Sustained Airflow Delivery

Under continuous load the fan maintains a steady 5V input to keep the internal impeller spinning without voltage sag. The 2.50W power rating supports consistent rotational speed during extended gaming or rendering sessions. This behaviour avoids the thermal throttling that occurs when a worn bearing slows down over time. The 4Pin interface allows the motherboard to modulate speed based on real-time temperature data.

Low-Noise Thermal Management

In normal use the fan runs at the factory-defined acoustic profile for the SUNON EG50050S1-1C050-S9A chassis. The 2.50W draw keeps power consumption modest while moving enough air to lower core temperatures. No additional power circuitry is required beyond the existing 4Pin header. Installers should verify the part number against the original unit using the supplied photos before fitting.
