HPE ML350 GEN11 EXT GPU FAN KIT - P47220-B21

HPE P47220-B21 External GPU Fan Kit for ProLiant ML350 Gen11

Overview

The HPE P47220-B21 is a dedicated external GPU fan kit engineered for the HPE ProLiant ML350 Gen11 tower server. When you install a discrete GPU or high-TDP accelerator card in an ML350 Gen11, the standard chassis airflow configuration may not deliver sufficient cooling to the expansion zone — this kit adds the supplemental fan capacity required to maintain thermal headroom and protect the GPU under sustained compute loads. Install it before commissioning any GPU workload to avoid thermal throttling or unplanned shutdowns.

Compatibility

Designed specifically for the HPE ProLiant ML350 Gen11 tower server. This kit is generation-specific — it is not interchangeable with ML350 Gen10, Gen10 Plus, or other ProLiant ML-series chassis. Confirm your server's generation via the system board label or iLO system information before ordering. If you are deploying GPU-accelerated workloads across a rack or tower server fleet, verify each chassis generation independently.

Installation Notes

This is a factory-new, genuine HPE spare sourced through US distribution channels — no grey-market, no parallel imports. Installation is performed inside the ML350 Gen11 chassis; power down and disconnect the server before fitting. Follow HPE's ML350 Gen11 maintenance guide for fan bay access and connector seating. The kit ships at 1.00 lb, reflecting compact fan module hardware. No additional tools beyond standard server maintenance equipment are required, but consult the HPE ML350 Gen11 server maintenance documentation for torque and connector specs specific to your configuration.
