Ruth's sister Z4G4 Memory Fan internal power cable

SKU CH-MXRB-CKMF5

Cools memory modules inside HP Z4 G4 workstations with a dedicated fan assembly

  • Compatible with HP Z4 G4 Workstation memory cooling assembly
  • Direct-fit replacement for original CPU cooler fan and chip cooling shroud
  • New condition ensures reliable memory fan operation
  • Purpose-built for HP Z4 G4 memory fan shroud installation

HP Z4 G4 Memory Cooling Fan

This internal cable connects the dedicated memory cooling fan assembly in HP Z4 G4 workstations. It delivers power to the shroud-mounted fans that direct airflow over memory modules and nearby chipset components. The part is designed for the specific mounting layout of the Z4 G4 chassis. Install it when replacing a faulty cable or reassembling the cooling subsystem after service.

Not for other workstations or custom builds

The connector pinout and cable length match only the HP Z4 G4 memory fan shroud. Builders using different HP workstation generations, third-party motherboards or aftermarket CPU coolers cannot use this cable. Buyers needing a standard PWM fan extension or a generic 4-pin power lead should look at universal cable kits instead.

Questions about this item

Will the Z4G4 Memory Fan connect to the existing fan headers on my HP Z4 G4 motherboard?

The Z4G4 Memory Fan is designed as a direct replacement for the HP Z4 G4 workstation, so it plugs into the original memory fan headers on the system board without adapters.

How can I confirm the Z4G4 Memory Fan is spinning correctly after installation?

After fitting the fan, boot the workstation and open the HP BIOS hardware monitor or use a tool like HWiNFO to verify the memory fan RPM reads a steady value above zero.
