Replacement Cooling Assembly

This new thermal module replaces the original fan and heatsink in the Lenovo Yoga C940-14IIL 81Q9 14-inch touch-screen laptop. It matches FRU 5H40S19974 and the listed manufacturer part numbers for UMA graphics configurations. The kit includes thermal grease for proper conductivity during installation.

UMA Graphics Laptop Owners

Buyers repairing a compatible Yoga C940 model with integrated graphics will find the correct 4-pin DC 5V 0.5A connector and form factor. Technicians needing a discrete-graphics cooling solution or a different laptop series cannot use this assembly.

4-Pin Power Connector

The module connects via a 4-pin 4-wire wire-to-board header drawing DC 5V at 0.5A. Verifying this exact connector on the motherboard is the single specification that confirms fit before purchase.

Questions about this item

How much power does the 5 V, 0.5 A fan draw from the 4-pin header during all-day use?

It runs on DC 5 V at 0.5 A, so the continuous draw is modest and well within the laptop's standard fan header budget.

What existing parts must I keep to install this replacement module?

You need to reuse the original mounting screws; the package supplies the fan-heatsink assembly and thermal grease only.

Will this UMA heatsink fit if my Yoga C940-14IIL 81Q9 already has the FRU 5H40S19974 installed?

Yes — the assembly matches FRU 5H40S19974 and the listed manufacturer part numbers for the UMA variant of this 14-inch model.
