HPE P48818-B21 – CPU Heat Sink Kit (Gen11 2U)

HPE P48818-B21 CPU Heat Sink Kit (Gen11 2U)

Overview

HPE P48818-B21 is an enterprise CPU heat sink kit designed for HPE ProLiant DL380 and DL560 Gen11 2U rack servers. It is used to dissipate heat generated by high-performance processors during continuous enterprise workloads. The heat sink works as a passive cooling component, transferring heat away from the CPU to maintain stable operating temperatures under heavy compute loads.
It is used in data center environments where servers run 24×7 for virtualization, cloud infrastructure, database processing, and enterprise applications. The component is part of the server’s thermal design and works together with system fans and airflow control to maintain safe operating conditions. It ensures consistent thermal performance and helps prevent CPU throttling under sustained workloads.

Typical Deployment Scenarios

Enterprise virtualization servers
Cloud and hosting infrastructure
Database and compute servers
High-density 2U rack environments
Mission-critical data center workloads
