Description

The HPE ProLiant DL325 Gen12 Closed-Loop Liquid Cooling Fan Kit (P81953-B21) is a purpose-built server cooling accessory for the ProLiant Compute DL325 Gen12 platform, designed to support AMD EPYC Gen5 processors operating at TDPs of 320W and above. It works exclusively alongside the HPE Closed-Loop Liquid Cooling Heat Sink (P81954-B21) and the Air Baffle Kit (P81928-B21), forming a compact radiator-based thermal management system optimised for 1U high-density rack deployments. Up to seven units may be required per server depending on memory and storage configuration.

Beyond thermal performance, this fan kit integrates with HPE iLO 7 for intelligent leak detection — automatically shutting down the server if coolant leakage is detected and preventing restart until the event is cleared, with REST API support for streamlined recovery. As a field-replaceable component with a recommended five-year service interval, it ensures long-term reliability for demanding enterprise workloads. Order direct from iptrading.com.au — Australian-owned and operated since 2001.

FAQs

Q: What is the HPE P81953-B21 used for?
A: The P81953-B21 is a Closed-Loop Liquid Cooling Fan Kit for the HPE ProLiant Compute DL325 Gen12 server. It is required when deploying AMD EPYC Gen5 processors with TDPs of 320W or higher, providing efficient thermal management within the server's integrated liquid cooling system.

Q: Does this fan kit work on its own, or do I need additional components?
A: This fan kit must be selected alongside the HPE Closed-Loop Liquid Cooling Heat Sink (P81954-B21) and the Air Baffle Kit (P81928-B21). All three components work together to form the complete closed-loop liquid cooling solution for the DL325 Gen12.

Q: How many fan kits do I need per server?
A: The number of fan kits required depends on your server configuration. Up to seven units may be needed for high-memory or 2SFF U.3 drive configurations. Check the HPE QuickSpecs for the DL325 Gen12 to determine the exact quantity for your build.

Q: Does this cooling kit support leak detection?
A: Yes. When integrated with HPE iLO 7, the system supports automatic leak detection. If coolant leakage is detected, the server will shut down automatically and will not power back on until the leakage event is cleared. REST API support is available for system recovery.

Q: Are there any configuration restrictions I should be aware of?
A: Yes. This fan kit is not compatible with GPU CTO server configurations, and it cannot be used with 256GB memory kits when certain ambient temperature tracking options are selected. Consult the DL325 Gen12 QuickSpecs for full compatibility details before ordering.

Q: Can I purchase the HPE P81953-B21 in Australia from iptrading.com.au?
A: Yes. iptrading.com.au is an Australian-owned and operated IT hardware reseller, in business since 2001. We supply genuine HPE server accessories including the P81953-B21 fan kit to businesses across Australia. Contact our team for pricing, availability, and volume enquiries.
