Z620 CPU Expansion Board Power Cable

This internal power cable connects the CPU expansion board in HP Z620 workstations using the LGA1366 socket. It carries 12V power through a 4PIN interface to the heatsink fan assembly. The part is intended for system builders or technicians servicing these specific workstations.

Installation Notes and Common Issues

The cable plugs directly into the 4PIN header on the expansion board, requiring no tools beyond opening the chassis. Misalignment of the keyed connector can prevent the fan from receiving power, so verify orientation before applying force. The supplier notes the unit is used but working good, so inspect the pins for bending before installation.

Interface and Practical Limits

The 4PIN power interface delivers a fixed 12V supply to a fan rated for 2000 to 3000rpm with a 100000 hour life expectancy. This connector type does not support PWM speed control, so the fan runs at full voltage whenever the system is powered. Builders needing variable fan curves must add a separate controller.

Questions about this item

How can I confirm the fan on the 647288-001 heatsink is running at the correct speed after installation?

The fan should spin between 2000 and 3000 rpm once the Z620 workstation is powered on; you can verify this in the system BIOS or hardware monitoring software.

Does the package include the CPU expansion board itself or only the heatsink with fan and 4-pin power cable?

The package contains the heatsink with integrated fan and 4-pin power connector for the Z620 CPU expansion board; the board (part numbers 618265-001 or 689471-001) is not included.

Which part number should I select if my workstation uses the 618265-001 or 689471-001 CPU expansion board?

This heatsink assembly (647288-001) is compatible with both the 618265-001 and 689471-001 Z620 CPU expansion boards.
