Replacement cooling fan for Yoga 900-13ISK

This new internal cooling fan carries part number 5H40K48422 and is built for the Yoga 900-13ISK laptop. It serves owners whose original CPU cooler has failed or become noisy. The component fits directly into the existing heatsink assembly for a straightforward repair.

Supplied as a single fan unit

The package contains only the cooling fan itself; no thermal paste, mounting screws or additional cables are included. Installers must reuse the original fasteners and apply fresh thermal compound during the swap. Buyers needing a complete heatsink assembly or extra installation hardware should look elsewhere.

Questions about this item

Does the 5H40K48422 fan require any periodic maintenance such as lubrication or cleaning?

The fan is a sealed replacement unit for the Yoga 900-13ISK; no lubrication is needed, but occasional cleaning of the heatsink fins with compressed air helps maintain airflow.

What is the first limit reached when the 5H40K48422 runs continuously under heavy load?

The limit is the thermal capacity of the laptop's heatsink assembly; once saturated, the fan cannot move enough air to lower CPU temperature further.
