ProLiant DL380 Gen11 heat-sink kit

This standard heat-sink kit is built for the HPE ProLiant DL380 Gen11 platform. It provides the factory-specified thermal interface for the server's processor sockets. System integrators and IT teams use it when assembling or servicing these rackmount servers.

Mechanical limits of the mounting pattern

The kit fits the exact mounting hole pattern and height envelope defined for the DL380 Gen11 chassis. It cannot be installed in other server models or generations because the retention mechanism and processor socket layout are unique to this platform. Physical dimensions are 16.7 x 20.4 x 16.1 cm.

Thermal capacity for standard processors

The 0.64 kg aluminium assembly is rated for the thermal design power of standard processors supported by the DL380 Gen11. It handles typical enterprise workloads within the server's validated operating range. Higher-power CPUs or dense configurations require the performance heat-sink variant instead.

Questions about this item

Is the P49145-B21 the only heat sink option for the DL380 Gen11, or are there performance variants?

The P49145-B21 is the standard heat sink kit for the DL380 Gen11; other variants such as high-performance kits exist for higher-TDP processors.

What does the 0.64 kg weight mean for thermal capacity in a live server?

The 0.64 kg mass provides the thermal inertia required for standard TDP CPUs in the DL380 Gen11 under sustained workloads.

How does the mounting interface align with the DL380 Gen11 socket layout?

The kit uses the DL380 Gen11-specific retention frame that locks onto the processor socket backplate for even pressure.
