Heatsink for Z420 and Z620 workstations

This HP heatsink assembly, part number 647287-001, is built for Z420 and Z620 workstations. It serves as a direct replacement processor cooler for those specific systems. Buyers needing a cooler for a different workstation model or a custom build should look elsewhere.

Questions about this item

How can I confirm the 647287-001 heatsink is operating correctly after fitting it in my Z420?

The fan should spin immediately on power-up and the workstation must complete POST without thermal warnings; CPU temperatures should stay within the processor's specified limits under load.

What components are included with the 647287-001 assembly and what must I source separately for installation?

The package contains the complete heatsink assembly with integrated fan and mounting hardware; thermal paste is not included and must be purchased separately.
