HPE P48817-B21 – CPU Heat Sink Kit

HPE P48817-B21 – CPU Heat Sink Kit

Overview

HPE P48817-B21 is an enterprise CPU heat sink kit designed for HPE ProLiant DL380 and DL560 Gen11 rack servers. It is used to dissipate heat generated by high-performance server processors during continuous workloads. The heat sink is a passive thermal component that transfers heat from the CPU into the chassis airflow system, where server fans remove it from the system. It is essential for maintaining stable processor temperatures and ensuring reliable server operation under heavy compute loads.
It is deployed in enterprise data center environments where servers run 24×7 under workloads such as virtualization, cloud infrastructure, database processing, and enterprise applications. The heat sink works as part of the server’s overall thermal design and ensures efficient heat transfer from the processor to the cooling system. It does not operate independently and depends on system airflow for proper cooling.

Typical Deployment Scenarios

Enterprise virtualization servers
Cloud infrastructure systems
Database processing servers
High-density rack environments
Mission-critical data center workloads
