## Summary description

HP Enterprise HEATSINK XL1X0R is a server-class heatsink featuring 18 fins designed to dissipate heat from compatible HPE server processors or components. It provides passive cooling through an array of fins to improve thermal management in rack or blade servers. Use it as a replacement or upgrade to restore proper cooling and maintain server stability under load.

## Long description

HP Enterprise HEATSINK XL1X0R is a server-class heatsink with 18 fins engineered to provide passive thermal dissipation for compatible HPE servers. Designed for rack and blade environments, this heatsink restores or improves cooling performance for processors or other heat-generating components, helping maintain stable operating temperatures under sustained load. The component is intended as a replacement or upgrade part to match specified HPE server cooling requirements.
Advantages
The 18-finned construction increases surface area to promote efficient heat transfer away from the component, enabling improved passive airflow cooling within server chassis. Its form factor and mounting points are made to align with compatible HPE server layouts, simplifying installation and ensuring reliable contact with the heat source. Using a server-specific heatsink helps reduce thermal throttling and supports consistent performance during continuous operation.
Suitable for
 Replacement of worn or damaged heatsinks in compatible HPE servers
 Upgrading thermal management in rack or blade server systems
 Maintaining stable processor temperatures under sustained computational load
Key specifications
 Cooling type: Passive heatsink with fin array
 Fins: 18 fins to increase dissipative surface area
 Material: Thermally conductive metal construction (typical for server heatsinks)
 Compatibility: Designed for specified HPE server models requiring this form factor
 Mounting: Server-compatible mounting interface and contact plate for processor/component cooling
How to use
Power down the server, disconnect power sources and follow anti-static procedures before beginning. Remove the server cover and existing heatsink according to the server manufacturer’s service manual, clean the processor or component contact surface, and apply a thin, even layer of thermal interface material if required. Position the HEATSINK XL1X0R so its contact plate aligns with the processor or component, secure it using the original mounting hardware or recommended fasteners, and reassemble the server. After installation, verify that the server boots and monitor operating temperatures to confirm proper thermal contact.
Usage recommendations
Use this heatsink only in supported HPE server models and follow the server manufacturer’s installation instructions. Ensure proper airflow within the chassis, maintain clean intake and exhaust paths, and verify thermal interface material condition during periodic maintenance to preserve cooling efficiency.
