CPU heatsink HP Enterprise BL460c Gen10 compatible — passive cooling for server CPU, replacement part

Replacement CPU heatsink compatible with HP Enterprise BL460c Gen10 servers. This passive cooling unit is designed to match the BL460c Gen10 form factor and mounting points, providing thermal conduction away from the processor in rack-mounted HPE blade systems. The part is intended as a direct replacement to restore original thermal performance and maintain stable CPU temperatures under typical data center loads.

Advantages

The heatsink is manufactured to fit the HP Enterprise BL460c Gen10 platform using the specified mounting positions and dimensions. As a passive cooling component, it provides reliable heat dissipation without active fans, allowing integration with the server chassis airflow design. This replacement part helps maintain expected thermal characteristics, reduces the risk of thermal throttling, and supports continued operation of processors certified for the BL460c Gen10.

Suitable for (tasks / use cases)

• Replacing a damaged or missing CPU heatsink in an HPE BL460c Gen10 blade server
• Restoring factory thermal performance after maintenance or upgrades
• Use in data center and rack-mounted blade enclosures that rely on chassis cooling
• Repair and refurbishment of BL460c Gen10 systems

Key specifications

• Compatibility: HP Enterprise BL460c Gen10
• Function: Passive CPU heatsink / replacement part
• Brand / OEM reference: HP Enterprise, MPN 877965-001-RFB
• Mounting: Designed for BL460c Gen10 socket and chassis mounting points

How to use

Power down the server and follow standard ESD precautions before beginning replacement. Remove the server blade from the enclosure and open any required access panels. Detach the existing heatsink by loosening the mounting screws or retention mechanism specified for the BL460c Gen10, then lift the heatsink straight off the CPU. Clean the CPU heatspreader and the heatsink contact surface using appropriate solvent or isopropyl alcohol, and apply the correct type and amount of thermal interface material as recommended for your processor. Position the replacement heatsink aligned to the mounting points and secure it with the original screws or retention mechanism to the manufacturer's specified torque. Reinstall the blade into the chassis and verify that chassis airflow components are functioning before returning the server to service.

Usage recommendations

Use this replacement heatsink only in BL460c Gen10 systems or other configurations confirmed compatible with HP Enterprise mounting specifications. Ensure proper thermal interface application and verify chassis fan operation to maintain adequate airflow. For servers under heavy or sustained load, monitor CPU temperatures after replacement to confirm expected cooling performance. If uncertain about installation, consult HPE service documentation or qualified service personnel.
