HPE ProLiant DL300 Gen10 Plus 2U Standard Fan Kit

The HPE P37042-B21 is a fan kit designed specifically for servers in the HPE ProLiant DL300 Gen10 Plus family. It replaces or supplements the original cooling fans in models such as the DL345, DL380, and DL385 Gen10 Plus, helping each system maintain the airflow it needs to stay stable under demanding workloads.

Because it matches the 2U form factor of these servers, the kit drops into place without forcing changes to your existing rack layout. Installation is straightforward and does not add noticeable weight, so a single technician can complete the swap during scheduled maintenance.

For administrators running virtualization clusters, database nodes, or other heat-intensive applications, reliable cooling can be the difference between nonstop productivity and unexpected downtime. This kit keeps processors, memory, and storage operating within optimal temperature ranges, which helps protect performance and extend component life.

Data centers, edge deployments, and on-premises server rooms that rely on the DL300 Gen10 Plus platform will find this kit a practical way to restore or improve cooling capacity while staying within the original hardware specifications.
