Replacement CPU Fan for Select Laptops

This DBTLAP cooling fan replaces the SUNON EG75070S1-C450-S9A unit in compatible laptops. It operates at DC5V with a 2.25W power rating and connects via a 4-pin interface. The package includes one tested fan unit ready for installation.

Buyers Replacing This Exact Part Number

This suits repair technicians and owners who have confirmed their laptop requires the EG75070S1-C450-S9A model with 4-pin connection. Buyers who need a different voltage, pin layout, or physical dimensions should look elsewhere as compatibility is strictly limited to this specific part number.

4-Pin Connector Determines Fit

The single specification that decides compatibility is the 4-pin connector configuration matching the original SUNON design. Verify your existing fan uses this exact pin arrangement before ordering because an incorrect connector will prevent installation and operation.

Questions about this item

How do I install the EG75070S1-C450-S9A fan and align the 4-pin connector correctly?

Remove the old fan, match the 4-pin connector to the motherboard header, secure the fan with the original screws, and verify the cable does not block the exhaust vent.

What maintenance will the DC5V 2.25W cooling fan need over time?

Clean dust from the blades and heatsink every few months with compressed air; replace the unit if bearing noise appears or airflow drops noticeably.

At what point does the 450 S9A fan hit its thermal limit during sustained load?

The fan runs at a fixed 5 V and 2.25 W; if the laptop chassis cannot dissipate the heat, CPU throttling will occur before the fan itself fails.
