Replacement CPU Fan for ADDA AB06505HX040BZ0

This new DBTLAP cooling fan replaces the original ADDA AB06505HX040BZ0 unit in compatible laptops. It arrives tested and ready to install as a direct swap for a worn or noisy cooler. Buyers who need a different voltage, connector layout or physical mounting pattern cannot use this part.

Four-Pin DC5V 0.50A Power Interface

The fan runs on a 4-pin header supplying 5 volts at 0.50 amps, so the motherboard must provide that exact voltage and current. Systems with 3-pin headers, 12-volt rails or lower current limits will not drive this cooler correctly. No adapter or voltage converter is included in the package.

Single-Fan Cooling Capacity for Targeted CPU Heat

One fan handles the thermal load of the specific processor the original ADDA cooler was designed for. It does not add extra surface area or airflow beyond the factory specification. Laptops with higher-wattage CPUs, multi-core upgrades or restricted venting will exceed the cooling headroom this single unit provides.
