The HPE P58456-B21 is a standard heat sink built for ProLiant DL3X5 Gen11 servers that occupy a single rack unit. Designed by the same team that engineered the server platform, it delivers the airflow and surface contact required to keep today’s high-core processors within safe temperature limits.
In day-to-day operation the heat sink helps your server sustain peak performance when workloads spike, whether you run dense virtualization pools, transaction-heavy databases, or real-time analytics. By drawing heat away from the CPU and channeling it into the chassis airflow, it protects system components from thermal stress, reduces the chance of unexpected throttling, and supports consistent uptime.
Installation follows the familiar HPE service-tool pattern, so an administrator can seat the unit, secure the spring-loaded screws, and return the server to the rack in minutes. Because the part is purpose-built for Gen11 1U models, fitment is exact, clearances are correct, and no aftermarket brackets or shims are required.
Data center operators, edge site managers, and system integrators who demand predictable cooling and official HPE support will find this heat sink a straightforward way to maintain reliability without altering their airflow design or budget.
