Server CPU Heatsink HP Enterprise BL460c 777689-001 for blade servers, passive cooling module

This replacement server CPU heatsink is designed for HP Enterprise BL460c blade servers and serves as a passive cooling module to dissipate heat from the processor area. It fits the BL460c platform and attaches to the server chassis mounting points to restore or maintain thermal management in blade server assemblies used in data center environments. The component is intended for maintenance and repair tasks where the original heatsink is damaged, degraded, or missing.

Advantages

The passive design requires no active fan power and integrates with the blade chassis airflow path to manage CPU temperatures under typical operating loads. Constructed to match the BL460c mechanical interfaces, it offers straightforward installation and reliable thermal contact with the processor region. Using a platform-specific heatsink helps preserve system stability, prevent thermal throttling, and maintain predictable cooling performance within compatible blade enclosures.

Suitable for

• Repair and replacement of heatsinks in HP Enterprise BL460c blade servers
• Maintenance of data center blade server racks where passive cooling modules are required
• IT technicians restoring thermal management after component failure or during upgrades
• Testing and refurbishing blade server units for resale or redeployment

Key specifications

• Compatibility: Designed for HP Enterprise BL460c blade server platform
• Cooling type: Passive heatsink module that relies on chassis airflow
• Mounting: Fits server chassis mounting points specific to BL460c blades
• Coverage: Targets the CPU/processor area for heat dissipation
• Form factor: Blade server compatible passive cooling component

How to use

Power down the blade server and remove it from the chassis following the server manufacturer's safety and handling procedures. Access the processor area by opening or removing the blade cover as specified for the BL460c platform. Replace the existing heatsink by aligning the module with the chassis mounting points and securing it according to HP Enterprise assembly instructions, ensuring proper seating and contact with any required thermal interface material. Reinstall the blade into the chassis and verify that system fans and enclosure airflow operate correctly before returning the server to service.

Recommendations

Use compatible thermal interface material where recommended, and follow anti-static precautions during handling. Verify that the blade chassis airflow and fan configuration are functioning as intended after installation to ensure effective passive cooling of the CPU area.
