Lenovo 5h40s20522 Heatsink Thermal Module L 82RD

Product Description

The LENOVO 5h40s20522 is a OEM heatsink and thermal module designed for Lenovo laptop systems. It manages heat dissipation from the processor and surrounding components, drawing thermal energy away from the die and transferring it through the heat pipe assembly to the exhaust fan. This part is intended for trained technicians performing component-level laptop repairs. The 5h40s20522 is a left-side thermal module variant, identified by the L designation in its product name, and is an AVC-manufactured assembly sourced directly from Lenovo's parts program.

This thermal module is suited for component-level repair of Lenovo notebook systems, specifically those matching the 82RD chassis designation. It is typically replaced when a system shows signs of thermal throttling, persistent high CPU temperatures, fan noise from a degraded heat pipe, or physical damage to the copper pipe or fin stack. Installation is performed by certified laptop repair technicians in both warranty service centers and independent repair shops.
