## Summary description

The HPE P48904-B21 is a heatsink designed for rack cooling in ProLiant DL3X0 Gen11 servers. With dimensions of 222 mm in width, 252 mm in depth, and 65 mm in height, it provides efficient thermal management to ensure optimal performance and reliability of your server equipment.

## Long description

The HPE P48904-B21 heatsink is a rack cooling component designed for compatibility with ProLiant DL3X0 Gen11 servers. With a compact footprint of 222 x 252 x 65 mm, this passive cooling element supports thermal management inside server chassis by increasing surface area for heat dissipation and enabling airflow-driven cooling in rack environments.
Advantages
The heatsink offers a space-efficient design that fits designated mounting positions in supported server models. Its dimensions and fin structure are engineered to improve passive heat transfer from processor or hot components to chassis airflow, helping maintain stable operating temperatures. The unit is built to meet data center deployment needs where predictable thermal behavior and mechanical compatibility are required.
Suitable for
Thermal management inside HPE ProLiant DL3X0 Gen11 rack servers
Replacement or upgrade of existing server heatsinks in compatible systems
Data center and enterprise server maintenance tasks
Key specifications
Form factor: rack-mount heatsink compatible with specified server chassis
Dimensions: approximately 222 mm (width) x 252 mm (depth) x 65 mm (height)
Cooling type: passive heatsink optimized for airflow-assisted dissipation
Material characteristics: thermally conductive construction designed for server environments
Mechanical compatibility: designed to align with mounting points and clearances in ProLiant DL3X0 Gen11 models
How to use
Power down the server and follow manufacturer procedures for safe handling and electrostatic discharge protection before servicing. Remove the server top cover or access panel to reach the existing cooling assembly. Detach the original heatsink following the server maintenance manual instructions, taking care to note mounting hardware and thermal interface material placement. Install the heatsink by aligning it with the designated mounting points, secure it with the appropriate fasteners, and apply the specified thermal interface material between component and heatsink if required. Reassemble the server chassis, verify seating and clearance, then power on and monitor system temperatures to ensure proper thermal operation.
Usage recommendations
Use only the thermal interface materials and mounting procedures recommended by the server manufacturer. Regularly inspect airflow paths, dust filters, and fan operation to maintain effective heat dissipation; replace the heatsink if physical damage or deterioration of thermal contact is observed.
