HP Spectre x360 14-EF 2-in-1 CPU Cooling Fan Pair with Heatsink Assembly

Product Description

Buy a compatible dual CPU cooling fan pair with heatsink assembly for HP Spectre x360 14-EF 2-in-1 laptops from LaptopHub. This replacement cooling assembly is designed for compatible HP Spectre x360 convertible laptops experiencing overheating, excessive fan noise, poor airflow, or cooling system malfunction.

The cooling assembly plays an important role in maintaining the laptop’s operating temperature. It consists of two cooling fans and a heatsink assembly that helps dissipate heat generated by the processor during everyday computing, multitasking, video streaming, and demanding applications.

A faulty cooling fan or damaged heatsink can result in excessive operating temperatures, unexpected thermal shutdowns, reduced performance, and loud or unusual fan noises. Replacing the complete cooling assembly may help restore proper airflow and thermal management.

This product is associated with HP spare part number N12234-001 and the following fan markings:

• CPU-side fan: ND55C99-21A08
• Companion fan: ND55C0A-21A09

The fans are side-specific and should be installed in their correct positions.

Before ordering, compare the original cooling assembly, fan labels, voltage, connectors, mounting points, and heatsink design with the replacement.
