Replacement CPU Fan for HP Pavilion X360

This new cooling fan replaces the original M45131-001 part in HP Pavilion X360 Convertible 15-ER 15-er00xx laptops. It restores active airflow to the processor heatsink when the factory fan has failed or become noisy. Installers should verify the exact model number before ordering because similar chassis use different fan assemblies. Buyers who need a complete heatsink assembly or a fan for a different 15-inch series cannot use this part.

Thermals noise and power draw in normal use

The fan draws power from the motherboard header and spins according to the system fan curve. Under typical office workloads it runs at low speed and stays quiet. During sustained loads the speed increases to move more air across the heatsink fins. No independent acoustic or power measurements are supplied with this replacement unit.

Questions about this item

How do I install the M45131-001 fan in my Pavilion X360 15-er00xx without damaging the ribbon cables?

Remove the bottom cover, disconnect the battery, unplug the old fan cable, unscrew the heatsink assembly, swap the fan, then reverse the steps; the ribbon cables near the hinge are fragile so lift them with a plastic spudger.

When should I replace the thermal paste on the heatsink while fitting this CPU cooling fan?

Reapply paste whenever the heatsink is lifted off the CPU or GPU die; clean both surfaces with isopropyl alcohol and use a pea-sized dot of non-conductive compound before re-mounting.
