## Summary description

HP Enterprise P58456-B21 is a processor heatsink/radiator designed for server and workstation cooling. Physical dimensions are 222 mm (W) × 252 mm (D) × 65 mm (H). It provides passive/active thermal dissipation for CPUs, fitting compatible HP systems to maintain stable temperatures under load and improve reliability and performance.

## Long description

HP Enterprise P58456-B21 is a processor heatsink/radiator designed to manage thermal load in compatible servers and workstations. With a compact footprint of 222×252×65 mm, the unit integrates a fin array and heat-spreading base to dissipate heat from the CPU effectively. It is intended for use in HP Enterprise platforms where controlled airflow and reliable thermal performance are required to maintain CPU operating temperatures under sustained workloads.
Advantages
The heatsink combines a dense fin structure and a conductive base to maximize heat transfer away from the processor while maintaining a relatively low profile for chassis compatibility. Its dimensions allow installation in constrained rack or tower environments without significant airflow obstruction. The design supports both passive heat conduction and integration with system fans for active cooling, contributing to stable thermal behavior and prolonged processor life when used as specified by the system manufacturer.
Suitable for
Server and workstation CPU cooling in compatible HP Enterprise systems
Replacement or upgrade in systems that accept the same form factor and thermal solution
Environments requiring reliable sustained cooling under continuous load
Key specifications
Primary function: processor heatsink / radiator
Overall dimensions: 222 mm (width) × 252 mm (depth) × 65 mm (height)
Cooling type: passive heat sink with capability to be used with system airflow for active cooling
Construction: fin array and conductive base for heat spread and dissipation
Compatibility: designed for installation in matching HP Enterprise server/workstation chassis that accept this form factor
How to use
Install the heatsink according to the chassis and motherboard instructions for the compatible HP Enterprise platform. Ensure the processor surface and heatsink base are clean and apply thermal interface material as specified by the system manufacturer. Align mounting points and secure the heatsink with the provided retention hardware or the system’s mounting mechanism to achieve proper contact pressure. When used with system fans, confirm that airflow direction matches the system design to optimize heat removal.
Usage recommendations
Verify platform compatibility before installation and follow HP Enterprise service documentation for torque specifications, thermal compound type, and mounting sequence. Maintain unobstructed airflow around the heatsink and perform periodic inspection to remove dust buildup that can reduce cooling effectiveness.
