## Summary description

Replacement heatsink by Lenovo, model 5H41B77164 (FRU HT4B0UMATHMASSYAVCAVC). Designed as an OEM cooling component for compatible Lenovo laptops or desktops. Provides passive or active heat dissipation for processors or related components depending on system configuration. Use to restore or maintain thermal management, reduce overheating and ensure stable operation of the device.

## Long description

Replacement heatsink from Lenovo designed for compatible Lenovo systems. This thermal module serves as an OEM cooling component intended to help manage heat from processors or nearby components, depending on the host system's cooling architecture. It restores or maintains thermal management in laptops or desktops where the original heatsink is damaged, degraded, or missing, helping to reduce thermal throttling and support stable operation under typical workloads.
Advantages
The heatsink is manufactured to match Lenovo's original equipment specifications, offering dimensional and thermal compatibility with systems designed for this form factor. Constructed from metals selected for thermal conductivity, it provides efficient passive or combined active cooling when paired with a compatible fan assembly. As a direct-replacement component, it simplifies repair or refurbishment by fitting into existing mounting points and thermal interfaces used by the original unit.
Suitable for
Repairing or refurbishing compatible Lenovo laptops and desktops
Replacing a damaged or worn heatsink to restore thermal performance
Maintaining stable processor operation under sustained workloads
Systems requiring OEM-compatible thermal modules for warranty or compatibility reasons
Key specifications
Function: passive or integrated cooling element for processor and nearby components
Material: thermally conductive metal alloy (heat-spreading surfaces and fins)
Mounting: designed to match original equipment mounting points and thermal interface areas
Compatibility: intended for use in supported Lenovo systems with matching mechanical and thermal design
Interface: contact surface for thermal pad or thermal paste to connect to processor or chipset
How to use
Before installation, power off the device, disconnect power sources and remove the battery if applicable. Access the internal area according to the device service guide to reach the existing heatsink assembly. Remove any retained screws and disconnect heat-pipe or fan connectors if present, then detach the old heatsink carefully from the processor and other contact points. Clean the contact surfaces on the processor and the heatsink contact area with isopropyl alcohol, apply an appropriate amount of thermal paste or replace thermal pads as required, and position the replacement heatsink aligning with mounting points. Secure fasteners evenly in sequence to the manufacturer’s torque recommendations and reconnect any fan or sensor connectors. Reassemble the device and verify fan operation and system temperatures after the first power-up.
Usage recommendations
Use correct service documentation and ESD protection during installation. Replace thermal interface material when installing the heatsink and verify that mounting pressure is even. If the system uses an active fan, ensure the fan assembly and airflow paths are clean and unobstructed to achieve expected cooling performance.
