    HP 749554-001 Z440 Z640 Workstation CPU HEATSINK Cooler HP P/N: 749554-001
    Aug 29, 2023
    Uses same fan as the standard Z4 G4 heatsink (3 pipe), just need a 5 pin connector and rewire.
    When I upgraded to a i9-9900 on my Z4 G4 I was getting a CPU heatsink error. Turns out this heatsink uses 4 pipes instead of 3 and the fan is the same as the standard heatsink. However the fan on this heatsink is a 6 pin and the standard Z4 G4 is a 5 pin. All you need to do is to rewire one of the fans so there is a jumper going from pin 3 to pin 5.
