Direct Replacement Fan

The DBTLAP cooling fan is a direct replacement for HP ENVY 17X, 17-CH, 17M-CH and 17T-CH laptops using part numbers TPN-W148, M45786-001, DFS5K123043637 or FNA6. It operates at 5V and 0.5A to restore factory airflow. Each unit is tested before shipping. Buyers who need a different voltage or connector should verify their original part first.

Steady Thermal Performance

Under sustained load the fan maintains consistent RPM to move heat away from the CPU heatsink without the speed spikes seen in worn bearings. The 5V 0.5A rating matches the original power budget so the motherboard header is not stressed. Dust buildup on the blades is the only factor that will reduce airflow over time.

Upgrade From Failed Original

This part replaces a noisy, stalled or error-reporting OEM fan and eliminates thermal throttling caused by insufficient airflow. The jump is worth it when the laptop shuts down under load or the BIOS reports a fan fault. It does not add extra cooling capacity beyond the design specification of the ENVY 17 series.

Questions about this item

Will the 5V 0.5A fan run quietly and stay cool when the laptop is under load all day?

The fan is rated at 5 volts and 0.5 amps, so it draws modest power from the laptop header and is designed for continuous operation inside the HP ENVY 17X, 17-CH, 17M-CH or 17T-CH chassis.

Do I need any extra cables, brackets or thermal paste to install this replacement fan in my HP ENVY 17 series laptop?

The package includes only the fan itself; reuse the existing mounting screws, connector and thermal interface material already present on the original heatsink assembly.

Will this fan fit the same motherboard header and screw holes as the original DFS5K123043637 FNA6 cooler in my TPN-W148 board?

Yes, it matches part number M45786-001 and the DFS5K123043637 FNA6 designation, so the connector pinout and mounting points align with the factory cooler used in the listed ENVY 17 models.
