Replacement CPU Fan for EG75070S1-C391-S99

This new DBTLAP cooling fan replaces the original CPU cooler in compatible laptops. It operates at DC5V with a 2.50W power draw and uses a 4Pin connector. The package includes one tested fan unit ready for installation.

Matching the EG75070S1-C391-S99 Part Number

The single specification that decides fit is the exact part number EG75070S1-C391-S99 printed on your existing fan. Voltage, wattage and the 4Pin interface must also match the original specifications. Buyers who need a different part number or a universal cooler cannot use this component.

Straightforward Swap with Visual Verification

Installation requires opening the laptop chassis, disconnecting the old 4Pin fan header and securing the replacement in the same mounting points. The most common error is ordering without comparing the product photos to the original fan layout. If the connector orientation or screw holes differ, the fan will not seat correctly.
