855966-001 CPU Cooling Fan Replacement for HP Pavilion X360 13-U M3-U TPN-W118 Series Laptop Cooler

This brand new CPU cooling fan is an exact aftermarket replacement part marked OEM code 855966-001, exclusively made for HP Pavilion X360 convertible laptops including 13-U series, M3-U, M3-U001DX, M3-U003DX, 13-U017TU, 13-U018TU, 13-U019TU and TPN-W118 chassis.

It features a 4-wire PWM connector that perfectly cooperates with the laptops built-in thermal management system to dynamically adjust rotation speed under light or heavy CPU loads. Ultra-thin curved turbine blades fit the narrow internal space of flip touchscreen laptops, delivering steady strong airflow to exhaust CPU heat efficiently.

It effectively fixes typical fan failures such as loud buzzing rattling, continuous high-temperature warnings, system slowdown and unexpected auto power-off caused by aging original coolers. Vibration-damping foam inside greatly cuts running noise during long-hour browsing, document editing and online classes.

Every fan passes strict airflow, voltage and durability factory inspection before delivery. Identical housing size, screw hole layout and cable length eliminate wiring cutting or chassis modification, enabling simple self-repair or professional maintenance. It is an affordable cooling spare part to restore full thermal performance of HP 13-inch X360 touchscreen notebooks.
