HPE P26491-001 – Server Chassis Fan Module

HPE P26491-001 – Server Chassis Fan Module

Overview

HPE P26491-001 is an enterprise hot-plug chassis fan module used in HPE ProLiant rack server platforms. It is designed to maintain consistent airflow inside the server chassis to ensure stable thermal conditions for CPUs, memory modules, and PCIe components under continuous workloads. The fan module is part of the system-level thermal management architecture and works in coordination with firmware and onboard sensors that adjust fan speed dynamically based on temperature and workload requirements.
It is deployed in enterprise data centers where servers operate 24×7 in virtualization, cloud infrastructure, database, and application hosting environments. The fan ensures balanced airflow across the chassis to prevent thermal hotspots and maintain system stability. It also supports redundant cooling design so that airflow continues even if one fan module fails, ensuring high availability and uninterrupted server operation.

Typical Deployment Scenarios

Enterprise virtualization environments
Cloud and hosting infrastructure
Database and application servers
High-density rack server deployments
Mission-critical data center workloads

Specifications

Compatibility / Ecosystem

HPE P26491-001 integrates into supported HPE ProLiant rack server systems as part of the internal cooling subsystem. It works with system sensors and firmware-based thermal control to dynamically regulate fan speed based on workload and temperature conditions. The module supports redundant operation within the chassis design, ensuring continuous airflow even under partial fan failure. It is widely used in enterprise environments where thermal stability, uptime, and predictable server performance are critical.
