Replacement heatsink for Lenovo 730S-13IWL

This new heatsink with integrated fan is built for the Lenovo 730S-13IWL laptop. It matches part numbers 5H40S72903, 81JB0004US and 023.100DO.0011. The assembly restores factory cooling performance for owners of this specific ultrabook model.

Direct swap installation with correct mounting

The cooler aligns with the original screw points and connector so no adapters or modifications are required. Thermal paste must be reapplied and the fan cable seated fully; skipping either step is the most common cause of overheating after fitting. Buyers needing a universal cooler or a different form factor should look elsewhere.
