Replacement thermal module for Yoga C940

This new thermal module includes the CPU cooling fan and heatsink assembly for Lenovo Yoga C940 models 15IRH 81TE and 9-15IMH5 82DE. It matches FRU 5H40S19977 and restores factory cooling performance in compatible laptops. Installers who need a direct-fit replacement for a worn or noisy original unit will find the correct part here.

Thermals noise and power in normal use

The integrated fan spins only when the processor temperature rises, keeping acoustic output low during light workloads. Heat pipes transfer energy from the CPU to the fin stack where airflow dissipates it without adding measurable system power draw. The assembly fits the existing mounting points so no case modification is required. Buyers who need a second module for a different chassis should verify compatibility before ordering.
