Replacement Fan for EG75070S1-C391-S99

This DBTLAP cooling fan is a direct replacement for the EG75070S1-C391-S99 part number. It operates at DC5V with a 2.50W power draw and uses a 4PIN connector. It is intended for laptop owners who need to replace a failed or noisy original cooler. Buyers who want a universal cooling pad or additional external airflow should look elsewhere.

Thermals, Noise and Power Draw

The fan runs on a 5 V supply and draws 2.50 W, matching the original specification for the EG75070S1-C391-S99 assembly. Each unit is tested before shipping to confirm correct operation. No acoustic or thermal performance figures are provided by the supplier.

Single Fan in Package

The package contains one cooling fan only. No mounting screws, thermal pads, cables or software are included. The supplier advises checking product photos against the old part and confirming the model number before ordering to ensure 100% compatibility.

Questions about this item

How do I install the 4PIN cooling fan in the EG75070S1-C391-S99 laptop, and what step is often missed?

Disconnect the battery, remove the old fan, connect the 4PIN plug to the motherboard header, secure the fan screws, then reconnect the battery; the step often missed is verifying the connector orientation before powering on.

What maintenance or replacement will the DC5V 2.50W fan need later?

Clean dust from the blades and heatsink every few months using compressed air; replace the fan if bearing noise appears or airflow drops below spec.

What limit appears first under sustained load with this 2.50W cooling fan?

The 2.50W power ceiling limits maximum RPM, so thermal throttling of the CPU or GPU occurs first when heat output exceeds the fan's dissipation capacity.
