Lenovo 5h40s72915 Thermal Assembly

Product Description

The LENOVO 5h40s72915 is a UMA thermal assembly designed for use in Lenovo laptop systems. This component manages heat dissipation from the processor and integrated graphics, directing thermal energy away from critical silicon to maintain stable operating temperatures. It is a direct OEM-style replacement part intended for installation by qualified computer hardware technicians performing board-level or component-level repairs on compatible Lenovo notebook platforms.

This thermal assembly is suited for depot-level laptop repair where the original heatsink or fan assembly has failed, is producing excessive noise, or has suffered physical damage. The AVC fan configuration noted in the part designation indicates dual-fan or dual-heatsink contact architecture typical of UMA (unified memory architecture) platform cooling solutions used in mid-range Lenovo notebook lines.

Key Features

• OEM Lenovo replacement thermal assembly for reliable fit and function
• UMA platform design integrates CPU and integrated GPU thermal management in a single unit
• AVC fan specification ensures compatibility with original airflow and noise profiles
• Direct drop-in replacement reduces rework time during depot repairs

Compatibility

Designed as an OEM-style replacement thermal assembly for compatible Lenovo notebook systems. Verify platform and chassis fitment against the service manual for the target unit before installation.

Installation Notes

Installation should be performed by a qualified technician familiar with laptop disassembly procedures. Power down the system completely and disconnect the battery before removing or installing any thermal components. Follow the manufacturer service manual for the correct screw torque sequence and thermal interface material application procedure. Reuse of degraded thermal paste is not recommended; apply fresh thermal interface material to all contact surfaces before reassembly.
