HPE P48908-B21 – Server Chassis Fan Kit

HPE P48908-B21 – Server Chassis Fan Kit

Overview

HPE P48908-B21 is an enterprise hot-plug chassis fan kit designed for HPE ProLiant DL380 Gen11 2U rack servers. It provides controlled airflow inside the server chassis to maintain optimal operating temperatures for CPUs, memory modules, and PCIe components under continuous workloads. The fan system is part of the server’s internal thermal architecture and works with system sensors and firmware-based control to adjust fan speed dynamically based on temperature and workload.
It is used in enterprise data centers where servers operate 24×7 under demanding workloads such as virtualization, cloud infrastructure, database systems, and application hosting. The fan kit ensures balanced airflow across the chassis, preventing thermal hotspots and maintaining stable system performance. It also supports redundant operation so that cooling continues even if one fan module fails.

Typical Deployment Scenarios

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

Specifications

Compatibility / Ecosystem

HPE P48908-B21 integrates into HPE ProLiant DL380 Gen11 server platforms as part of the internal cooling system. It works with system sensors and firmware-based thermal control to dynamically regulate airflow based on temperature and workload conditions. The fan kit supports redundant operation within the chassis design, ensuring continuous cooling even under partial component failure. It is widely used in enterprise environments where thermal stability, uptime, and consistent server performance are critical.
