Direct replacement for HP ENVY 17X TPN-W148

This new DBTLAP cooling fan matches part number M45787-001 and runs on DC 5V power. It is built for owners of the HP ENVY 17X series who need to swap out a worn or noisy original unit. The package contains one tested fan ready for installation. Buyers who need a different voltage or connector should look elsewhere.

Sustained airflow at rated voltage

The fan delivers continuous cooling at its specified 5V input without relying on short bursts of higher speed. Each unit is tested before shipping to confirm stable operation under load. This steady performance helps keep internal temperatures consistent during extended sessions. Laptops that require variable-speed control beyond the original spec will not benefit.

Upgrade from a failed or loud OEM fan

Replacing the original cooler with this direct-fit part restores the factory thermal profile when the old fan has seized, rattles or no longer spins. The jump is worth it when the laptop throttles or shuts down due to heat. Systems with damaged mounting points or a different chassis design cannot use this fan.
