HPE ProLiant DL380/DL560 Gen11 High Performance 2U Heat Sink Kit (P48818-B21)

The HPE ProLiant DL380/DL560 Gen11 High Performance 2U Heat Sink Kit (P48818-B21) is a vital thermal solution engineered explicitly to manage high-temperature thresholds in enterprise data centers. As compute requirements scale up, standard cooling sinks quickly hit their physical limits. This factory-certified, heavy-duty passive heatsink is engineered to dissipate massive thermal loads, ensuring that high-performance 4th and 5th Generation Intel® Xeon® Scalable processors can run at maximum clock speeds without hitting thermal throttling boundaries.

Designed around a 2U rack architecture, the P48818-B21 is an absolute prerequisite when deploying processors with Thermal Design Power (TDP) ratings ranging from 150W up to 350W (such as the Intel Xeon Gold 6430 or high-end Platinum models). Sized precisely to match the physical airflow lanes of modern ProLiant motherboards, this kit prevents internal hot zones, safeguards nearby memory banks, and drops server downtime risks caused by overheating.

HPE ProLiant DL380/DL560 Gen11 High Performance 2U Heat Sink Kit (P48818-B21) Key Features & Product Highlights

• Engineered for High-TDP Processors: Specialized for high-draw hardware environments, easily cooling processors rated from 150W up to a massive 350W TDP.

• Custom 2U Spatial Profile: Formed precisely to seat within the 2U chassis profile of the DL380 and DL560 Gen11 servers, routing high-velocity internal airflow cleanly over thermal plates.

• Advanced Multi-Pipe Thermal Copper Deck: Integrates thick internal copper heat pipes wrapped within an ultra-dense aluminum fin matrix to instantly pull heat away from the processor core.

• Essential Dual-Socket Upgrade Tool: Serving as a primary enablement option, this kit provides the standalone hardware cooling stack necessary when adding a secondary physical CPU to your server mainboard.

• Maintains Sustained Turbo Boost: Keeps running temperatures low, giving the system hypervisor the thermal room needed to maintain Intel Turbo Boost performance under extended workloads.

• Genuine Factory Retention Integrity: Features official heavy-duty retention clips to maintain steady, uncompromised pressure over the CPU socket interface, preventing thermal paste gaps.

HPE ProLiant DL380/DL560 Gen11 High Performance 2U Heat Sink Kit (P48818-B21) Pros & Cons

Pros

• Prevents Thermal Degradation: Keeps demanding multi-core processors running comfortably cool, significantly expanding the operational lifespan of your underlying server hardware.

• Eliminates Performance Drops: Keeping temperatures below critical silicon boundaries prevents the server from down-clocking its processing speeds during compute spikes.

• Zero Moving Components: The completely passive mechanical layout avoids additional electrical power consumption or mechanical moving parts that could break down over time.

• Perfect Structural fit: Built as an official factory option, ensuring a fast, hassle-free installation that locks perfectly with Gen11 CPU retention brackets.

Cons

• Strict Structural Exclusivity: Tailored purely for the internal spacing of 2U Gen11 chassis layouts. It will not physically fit or seal inside 1U servers (like the DL360 Gen11) or older Gen10 platforms.

• Requires Strong Chassis Airflow: Because it is a passive heat sink, it depends on active server fans. Dense server builds running high-TDP CPUs will likely need to pair this with the HPE High-Performance Fan Kit (SKU: P48820-B21) to ensure proper cooling.

HPE ProLiant DL380/DL560 Gen11 High Performance 2U Heat Sink Kit (P48818-B21) Suitable Application Areas

• Symmetric Multiprocessing (SMP) Upgrades: A mandatory cooling upgrade when transforming a single-CPU server into a dual-socket system with high-power processors.

• High-Density Cloud Computing Nodes: Essential for virtualization layers running dense workloads that keep processor utilization rates locked at high percentages.

• Hot Office Data Racks: A smart, protective addition for server rooms across Kenya that lack specialized climate controls or battle elevated ambient room temperatures.
