HPE P48820-B21 2U Server Fan Kit

Overview

HPE P48820-B21 is a server cooling fan kit designed for HPE ProLiant Gen11 2U rack servers. It is used to maintain proper airflow inside high-density server chassis where CPU and memory components generate continuous heat during enterprise workloads. The fan system ensures stable thermal balance so the server can run at consistent performance without overheating or throttling. It is built for data center environments where servers operate 24×7 under heavy compute load.
It is commonly used in enterprise environments running virtualization, cloud infrastructure, database systems, and application hosting. The fan kit works as part of the internal thermal design of the server, ensuring uniform cooling across all critical components. It also supports system-controlled fan speed adjustment based on workload and temperature conditions.
