Genuine Cooling Fan & Heatsink for Legion Y545

This replacement part is built for the Legion Y545 series. It combines the fan and heatsink into a single assembly that matches the original 5H40S19931 specification. The unit restores factory cooling performance for compatible laptops. Install it to return the system to its intended thermal profile.

Replaces a worn or failed original cooler

Swap this in when the existing fan runs loud, spins slowly or the heatsink no longer transfers heat efficiently. The jump is worth it if thermal throttling appears under load or the original assembly has physical damage. It is not for owners of other Legion models or different laptop brands. Buyers needing a universal external cooling pad should look elsewhere.
