    Package arrived quickly, and the items were as described. Packaging, on the other hand, was terrible. The cooler arrived with bent cooling fins. Just dumped in the box (a very weak box on its 3rd or fourth trip through the mail) next to a cooling fan. The fan was wrapped in bubble wrap that I would use for a much larger item, so it really didn't help any when the weak box was crushed in transit. Fortunately I only needed to CPU cooling fan and not the heatsink.

    HP Z420 high cpu temps problem - solved!

    The CPU heatsink and fan in my recently acquired HP Z420 desktop workstation weren't up to the job of cooling its Xeon E5-1650 6-core processor, as evidenced by CPU temps well above the 65 degree max operating temperature when running at 25% capacity or higher for any length of time. Max CPU temps for heavy processing jobs maxed out at 80+ degrees. I'd investigated and followed up on all the usual suspects, i.e. accumulated dust, dried out thermal compound, fans' operation and internal airflow without any significant change. I saw that others online had run into similar problems and saw lots of frustration but no solutions. Then I realized that HP had redesigned the CPU heatsink and fan for the newer Z440 workstation and it all made sense: their solution was increasing the size and ...

  • 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.

  • Upgrade the Z420!

    I upgraded my Z420 from 1620v2 to a 2667v2. This heatsink is centered and has four tubes rather the three of a stock Z420. With 100% usage of all cores. It keeps the temp well below the max operating temp. But you will have to use the original fan. Hp makes them board specific. But it fits perfectly. Happy upgrading!

  • Great Price for Heat Sink.

    Arrived on time and packaged well and clean. Used to upgrade the cooler on the second processor of a z620 workstation. The difference is that the z620 heat pipes are on top of the cooling block while the z640 heat pipes are integrated into the cooling block. The z620 heat block can warp over time while the z640 dose not.
