HPE P27095-B21 High Performance Heat Sink Kit for ProLiant DL380 Gen10+
Overview
The HPE P27095-B21 is a high-performance heat sink kit designed for the ProLiant DL380 Gen10+ server platform. When your DL380 Gen10+ is configured with high-TDP processors — such as Intel Xeon Scalable CPUs running at elevated power envelopes — the standard heat sink may not deliver adequate thermal headroom. This kit provides the increased cooling surface and airflow capacity required to keep those processors within spec under sustained load, protecting both performance and hardware longevity. If you're upgrading processor configurations post-deployment or building out a thermally demanding compute node, this is the component to source alongside the CPU upgrade.
Compatibility
This kit is engineered specifically for the HPE ProLiant DL380 Gen10+ platform. It is not interchangeable with DL380 Gen10 (non-Plus) or other ProLiant generations — the Gen10+ chassis uses a revised motherboard layout and processor socket arrangement that requires its own thermal solution. Verify your server's chassis generation before ordering: the Gen10+ designation appears on the system board label and iLO system information page. For high-performance processor configurations on the DL380 Gen10+, HPE's configuration guides specify this heat sink as the required thermal option — consult your processor's TDP against HPE's thermal matrix to confirm this kit applies to your CPU selection.
Installation Notes
At 1.76 lb and 11.50 x 10.00 x 5.00 in, this is a full-size 2U heat sink assembly — plan for brief server downtime and full chassis access. Installation requires removing the access panel and any riser cages blocking the processor bay. Follow HPE's documented torque sequence for processor retention and heat sink mounting screws; improper torque risks uneven contact and thermal throttling. Ensure server airflow baffles are correctly seated after installation — the DL380 Gen10+ relies on directed airflow through the baffle to maintain rated cooling performance across the heat sink fin stack.
