Questions & Answers
What is the HP DL380 Gen9 High Performance Heatsink FIO Kit?
A field‐installable heatsink assembly designed to enhance CPU cooling efficiency in HP ProLiant DL380 Gen9 servers.
Which servers are compatible with the HP DL380 Gen9 Heatsink FIO Kit?
This kit is fully compatible with all HP ProLiant DL380 Gen9 rack-mount servers.
What thermal performance improvements does the High Perf Heatsink provide?
It lowers CPU junction temperatures by up to 10 °C under peak load, improving stability and lifespan.
How do I install the DL380 Gen9 High Perf Heatsink FIO Kit?
Power down the server, remove the old heatsink, apply provided thermal interface material, then secure the new heatsink per the Quick Install Guide.
Is thermal interface material included in the kit?
Yes. The kit includes pre-applied, high-performance thermal interface pads for immediate installation.
Are any special tools required for installation?
No. Standard Phillips-head screwdrivers included in your server tool kit are sufficient.
Can this heatsink support high-TDP processors?
Yes. It’s engineered to handle up to 150 W TDP CPUs commonly used in DL380 Gen9 configurations.
How does the High Perf Heatsink improve server reliability?
By maintaining optimal CPU temperatures, it reduces thermal throttling and minimizes hardware faults over time.
What materials are used in this heatsink assembly?
Constructed from high-density aluminum fins and copper heat pipes for maximum thermal conductivity.
