Replacement 4010 cooling fan

The DBTLAP 4010 is a 5 V 0.5 A four-wire fan designed to replace the PFNK PA4010S05HN2 unit in compatible laptops. It ships as a single tested fan without mounting hardware. Buyers must verify the part number and photos against the original component before ordering.

Upgrading from a failed or noisy original

This fan replaces an identical 4010 model that has stopped spinning or developed bearing noise. The jump is worth it when the laptop throttles due to a dead cooler and the part number matches exactly. It is not for buyers who want higher airflow, a different voltage or a larger frame size.

Limits of the four-wire 5 V interface

The four-wire connection provides speed reporting and PWM control only within the 5 V 0.5 A rating of the original header. It cannot draw more current or support voltage levels outside that spec. Builders needing a different pin-out, higher voltage or greater airflow must choose another part.

Questions about this item

What size fan fits the PFNK PA4010S05HN2 mounting holes?

The 4010 fan uses a 40 mm square frame with standard screw spacing that matches the PFNK PA4010S05HN2 cut-out.

How do I connect the four wires correctly during installation?

Match the 5 V power, ground, PWM control and tachometer leads to the motherboard header; reversing the PWM and tach wires is the common mistake.

When should I plan to replace this 5 V 0.5 A cooling fan?

Expect several years of continuous use; replace when bearing noise increases or the tachometer signal drops out.
