P48817-B21 HPE ProLiant DL380 Gen11 Max Performance Heat Sink Kit

The HPE P48817‑B21 ProLiant DL380 Gen11 Max Performance Heat Sink Kit is a high‑efficiency thermal management solution purpose‑built for the HPE ProLiant DL380 Gen11 rack server platform. Engineered to address the cooling demands of high‑power, compute‑intensive processors—including Intel Xeon 6 series CPUs with thermal design power (TDP) ratings up to 350W—this heatsink kit delivers superior heat dissipation to maintain optimal operating temperatures, prevent thermal throttling, and preserve peak performance under sustained heavy workloads.

As an HPE OEM‑certified component, it integrates seamlessly with the DL380 Gen11 chassis, utilizing factory‑engineered mounting points and thermal interfaces to ensure maximum thermal transfer efficiency. Designed for mission‑critical data center environments, edge computing deployments, and virtualized infrastructure, this heatsink kit is an essential upgrade for organizations requiring reliable, high‑performance cooling to support demanding applications such as AI inference, big data analytics, database management, and high‑performance computing (HPC). By maintaining strict thermal control, it extends the operational lifespan of critical server components, reduces unplanned downtime, and enhances overall system reliability.

Featuring an advanced fin‑stack design with increased surface area and optimized airflow channels, the P48817‑B21 heatsink kit efficiently transfers heat from high‑power processors to the surrounding air. This design is specifically calibrated to handle processors with TDP ratings up to 350W, making it ideal for the most demanding DL380 Gen11 configurations. By eliminating thermal bottlenecks, it ensures the server's CPU operates at full clock speeds without throttling, even during 24/7 peak workloads.

Exclusively engineered for the HPE ProLiant DL380 Gen11 server, this heatsink kit guarantees perfect compatibility with the server's motherboard, processor socket, and chassis constraints. It aligns precisely with factory mounting holes and utilizes HPE‑approved thermal interface materials (TIM) to ensure optimal thermal contact. This eliminates compatibility risks and ensures the heatsink performs as intended, maintaining the server's original warranty coverage.

Constructed from high‑grade aluminum alloy with a robust mounting bracket system, the heatsink kit is built to withstand the rigors of continuous data center operation. Its rigid design resists vibration and mechanical stress, ensuring stable performance over its lifespan. The matte black finish aligns with HPE's industrial design standards, facilitating easy identification during maintenance and service operations.

The heatsink's form factor and fin orientation are precisely engineered to work in harmony with the DL380 Gen11's standard and high‑performance fan kits. This synergy maximizes airflow through the heatsink fins, significantly improving overall cooling efficiency. This integrated approach ensures that the entire server's thermal management system operates as a cohesive unit, providing balanced cooling across all critical components.

Designed for straightforward installation by IT technicians, the kit includes all necessary mounting hardware and a pre‑applied high‑quality thermal pad. The tool‑less or standard tool installation process minimizes service time, allowing for quick upgrades or replacements. This ease of serviceability reduces maintenance windows and operational disruptions in busy data center environments.

The P48817‑B21 kit is packaged in a custom, anti‑static, shock‑absorbent box to protect the precision heatsink fins and components during transit. The package dimensions are 10.2 in x 8.3 in x 4.7 in (25.9 cm x 21.1 cm x 11.9 cm) with a gross weight of 2.87 lbs (1.30 kg), complying with standard shipping carrier requirements.
