HPE P81955-B21 | ProLiant DL325 Gen12 Performance Air-Cooled Heat Sink, up to 320W

Q: Which server is this heat sink kit compatible with?
A: The HPE P81955-B21 Performance Heat Sink Kit is specifically designed for the HPE ProLiant Compute DL325 Gen12 server. It is not a universal heat sink and should not be used in other ProLiant server generations or models.

Q: What is the maximum processor TDP this heat sink supports?
A: This performance-tier heat sink supports AMD EPYC 9005 Series processors with a thermal design power (TDP) of up to 320W, making it suitable for high-core-count, high-power processors used in intensive compute workloads.

Q: Do I need any additional parts to install this heat sink kit?
A: Yes. The HPE Air Baffle Kit (P81928-B21) is required alongside this heat sink to ensure correct airflow channelling within the DL325 Gen12 chassis. Both the standard and performance heat sink configurations require this baffle kit.

Q: How does this differ from the standard heat sink option for the DL325 Gen12?
A: The performance heat sink is rated for higher processor TDPs — up to 320W — compared to the standard heat sink, which is designed for lower-TDP processor configurations. If you are deploying high-wattage AMD EPYC 9005 processors, the performance tier is required.

Q: Can I purchase this heat sink kit in Australia through IP Trading?
A: Yes. The HPE P81955-B21 Performance Heat Sink Kit is available at iptrading.com.au. IP Trading is an Australian B2B IT hardware reseller offering competitive pricing and local support for HPE server accessories.

Q: Is liquid cooling available for the DL325 Gen12 as an alternative?
A: Yes. HPE offers a tiered cooling solution family for the DL325 Gen12, including standard air cooling, this performance air-cooled option, and closed-loop liquid cooling for the most thermally demanding configurations. Contact IP Trading to discuss the right cooling solution for your deployment.
