Replacement Fan For EG75070S1-C391-S99

This DBTLAP cooling fan is a direct replacement part for the EG75070S1-C391-S99 laptop cooler. It operates on DC 5V power and draws 2.5W. The 4PIN connector ensures proper fit and control. Buyers who need a different voltage or pin layout cannot use this unit.

Sustained Airflow At Rated Power

The fan delivers continuous cooling at its rated 2.5W without thermal throttling. DC 5V input keeps current draw stable during long sessions. Each unit is tested before shipping to verify operation. Builders who expect variable speed curves beyond the fixed specification will not find them here.

Four Pin Connector Limits

The 4PIN interface provides power and tachometer signal only. It does not carry PWM control unless the host board implements it. Compatibility depends on an exact match to the EG75070S1-C391-S99 part number. Technicians who assume universal pinouts across models risk ordering the wrong part.
