HPE P48818-B21

Overview

The HPE P48818-B21 is a high-performance heat sink kit designed specifically for ProLiant DL380 and DL560 Gen11 servers. Its primary function is to efficiently transfer processor heat into the system airflow, enabling the server to maintain full CPU clock speeds even under heavy workloads. This cooling solution is essential for environments where virtualization, database processing, or analytics demand sustained turbo performance from every core.

Key features

• Effectively moves heat away from the CPU to prevent thermal throttling during peak processing loads
• Designed to fit within a 2U rack chassis without obstructing nearby DIMM slots or PCIe risers
• Compatible with Gen11 Network Choice Server configurations, ensuring optimal cooling for modern server setups
• Quick installation using the standard Gen11 retention mechanism, minimizing server downtime during maintenance
• Lightweight assembly at 0.78 kg, making handling and installation straightforward for technicians

Key specs

• Compatibility: HPE ProLiant DL380 and DL560 Gen11 servers
• Form factor: 2U heat sink kit
• Weight: 0.78 kg
• Dimensions: 25.3 cm (W) × 28.8 cm (D) × 13.5 cm (H)

Installation and setup

The heat sink kit aligns precisely with Gen11 mounting points and uses the standard retention mechanism, allowing most IT technicians to install it during routine maintenance windows. This design keeps server downtime short and predictable, which is critical in enterprise environments where uptime is a priority.

Ideal uses and environments

This heat sink kit is well suited to data centers and enterprise IT environments running ProLiant DL380 or DL560 Gen11 servers. It supports workloads that push CPUs to sustained turbo speeds, such as virtualization hosts, database engines, and analytics clusters. By maintaining optimal thermal conditions, it helps ensure consistent server performance during demanding tasks.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
