P48905-B21 HPE ProLiant DL3XX DL560 Gen11 High Performance Heat Sink Kit

The HPE P48905‑B21 ProLiant DL3XX/DL560 Gen11 High Performance Heat Sink Kit is a purpose‑built thermal management solution engineered exclusively for HPE's DL360 Gen11, DL380 Gen11, and DL560 Gen11 rack‑mounted server platforms. Designed to address the elevated cooling demands of high‑TDP (Thermal Design Power) processors in dense compute environments, this heatsink kit delivers exceptional heat dissipation to maintain optimal operating temperatures, eliminate thermal throttling, and preserve sustained peak performance under the most demanding workloads.

As an HPE OEM‑certified component, it integrates seamlessly with the server chassis, leveraging factory‑engineered mounting points and thermal interfaces to ensure maximum thermal transfer efficiency. Ideal for data centers, virtualization clusters, database servers, and high‑performance computing (HPC) deployments, this heatsink kit is critical for organizations requiring reliable, high‑efficiency cooling to support mission‑critical applications while extending hardware lifespan and minimizing unplanned downtime.

Featuring an advanced fin‑stack design with an expanded heat‑dissipating surface area and optimized airflow channels, the P48905‑B21 kit efficiently transfers heat from high‑power processors to the server's internal airflow. This design is specifically calibrated to support processors with TDP ratings up to 270W, making it ideal for the most demanding DL3XX/DL560 Gen11 configurations.

Uniquely certified for HPE ProLiant DL360 Gen11, DL380 Gen11, and DL560 Gen11 servers, this heatsink kit guarantees perfect compatibility with the motherboard, processor socket, and chassis layout of all three platforms. It aligns precisely with factory mounting holes and utilizes HPE‑approved thermal interface materials (TIM) to ensure optimal thermal contact.

Engineered to fit within the strict spatial constraints of rack‑mounted servers, the heatsink's compact dimensions ensure unobstructed access to adjacent DIMM slots, PCIe risers, and other internal components. This precision engineering prevents physical interference during installation and operation while delivering maximum cooling performance.

Constructed from high‑grade aluminum alloy with a durable matte black finish, 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 an extended lifespan.

The heatsink's fin orientation and overall geometry are precisely engineered to work in harmony with the DL3XX/DL560 Gen11's high‑performance fan kits. This synergy maximizes airflow through the heatsink fins, significantly improving overall cooling efficiency and ensuring balanced thermal management.

Designed for straightforward installation by IT technicians, the kit includes all necessary mounting hardware and a pre‑applied high‑performance thermal pad. The standard tool installation process minimizes service time, allowing for quick upgrades or replacements during routine maintenance windows.

The P48905‑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 10.6 in x 12.0 in x 5.9 in (27.0 cm x 30.5 cm x 15.0 cm) with a gross weight of 1.05 kg (2.31 lbs), complying with standard shipping carrier size and weight limits.
