## Summary description

Replacement heatsink designed for Lenovo servers, identified by manufacturer part number 04W3747. This cooling module serves to dissipate heat from processor or server components, maintaining thermal stability and preventing overheating. Suitable for use in maintenance, hardware repair, or server refurbishment where OEM-compatible cooling is required.

## Long description

Replacement heatsink designed for Lenovo servers to restore effective thermal management of the processor and adjacent components. This cooling module is an OEM-compatible part intended for installations where original or equivalent passive cooling is required to maintain stable operating temperatures and prevent thermal throttling or shutdowns. The component fits into server systems that accept the specified form factor and mounting layout, providing a direct path for heat transfer away from critical chips.
Advantages
The heatsink offers reliable passive heat dissipation through a metal fin and base assembly engineered for server environments. It is compatible with standard mounting points and thermal interfaces used in Lenovo rack and tower servers, ensuring consistent contact with the processor or other hot components. The design minimizes airflow restriction and integrates with existing chassis cooling to support continuous operation under load.
Suitable for
 Hardware repair and part replacement in Lenovo server maintenance
 Server refurbishment and component upgrades
 Preventive maintenance to restore thermal performance
Key specifications
 Type: Passive heatsink cooling module for server CPUs and components
 Material: Metal base and fin assembly for efficient heat conduction
 Compatibility: Designed to match Lenovo server mounting and thermal interface requirements
 Function: Dissipates heat from processor or nearby server components to maintain thermal stability
How to use
Power down the server and follow electrostatic discharge (ESD) precautions before starting. Remove the existing heatsink or access the processor area according to the server service manual. Clean the mating surfaces of old thermal compound and apply a suitable thin, even layer of thermal interface material if required. Align the heatsink with the designated mounting points and secure it using the original fasteners or those specified by the server documentation. Reassemble the server, restore power, and monitor temperatures to confirm correct installation.
Usage recommendations
Use manufacturer-recommended thermal compound and follow the server vendor’s torque and installation procedures. Verify airflow paths and chassis fan operation after installation to ensure combined cooling performance. Replace the heatsink if fins are bent, base surfaces are damaged, or if thermal performance remains inadequate after proper installation.
