DBTLAP CPU cooling fan Samsung Book NP550XDA BNA107S5H-N00P HQ23300086000 5V 0.45A

Replacement CPU fan for Samsung Book NP550XDA

This new DBTLAP cooling fan is a direct replacement part for the Samsung Book NP550XDA laptop. It operates at 5V and 0.45A to match the original power specifications. The unit is intended for owners who need to swap a worn or noisy internal cooler. Each fan is tested before it leaves the supplier.

5V 0.45A cooling capacity and headroom

The fan draws 0.45A at 5V to move air through the laptop's existing heatsink assembly. It comfortably handles the thermal load of the NP550XDA chassis under normal workloads. Headroom diminishes when sustained heavy loads push the heatsink beyond its dissipation limit. The single included fan replaces the original unit without adding extra airflow paths.

Upgrades a failing original cooler

This part replaces the factory BNA107S5H-N00P fan when bearings wear out or airflow drops. The jump is worth it when the original cooler runs loudly, spins erratically or fails to keep temperatures in check. It is not for buyers who want additional external cooling pads or a higher-specification internal upgrade. Compatibility depends on matching the exact part number shown in the photos.
