Heatsink/Radiator HPE P58458-B21 203.2mm x 160.3mm x 166.8mm

The HPE P58458-B21 heatsink/radiator is a precision cooling component designed for server and workstation processors. With external dimensions of 203.2mm x 160.3mm x 166.8mm and a compact 0.84 kg mass, this HP Enterprise part provides a balance of thermal dissipation capacity and space-efficient installation for systems that require reliable heat removal under sustained loads.

Advantages

This heatsink/radiator offers a form factor optimized for compatibility with HP Enterprise hardware layouts while delivering efficient passive and forced-air heat transfer. Its metal fin structure and mounting footprint are intended to reduce hotspot formation on the processor and to support consistent thermal performance during prolonged high utilization. The modest weight simplifies handling and installation in rack or tower chassis where component density matters.

Suitable for

• Server and workstation processor cooling in HP Enterprise systems
• Environments that require continuous operation and stable thermal management
• Hardware maintenance or upgrade tasks where original-equipment form factor is preferred

How to use

Install the heatsink/radiator on the processor according to the server or workstation manufacturer's service instructions. Ensure the mating surfaces are clean and apply appropriate thermal interface material between the processor and the heatsink base. Secure the component using the original mounting points and hardware to achieve correct contact pressure. After installation, verify airflow direction and clearance to adjacent components to maintain unobstructed ventilation paths.

Recommendations

For reliable operation, use this heatsink/radiator within systems that follow HP Enterprise mechanical and thermal specifications. Regularly inspect the fins and airflow passages for dust accumulation and clean as part of scheduled maintenance. When replacing or upgrading, confirm mechanical compatibility with the chassis and cooling fan arrangement to preserve intended thermal performance.
