This is what you are looking for with regards to HP part number;

If you search on ebay you will find these listed from under £50.

Hi Tony_atfpodcast,

 

Here are a couple of documents that will help;

 

HP Z420 Quickspecs

HP Z420 User Guide

HP Z420 Maintenace and Service Guide

 

The Quickspecs lists all compatible Xeon CPU's with their clock speeds, core count, etc. I would probably opt for the E5-1680 v2 CPU - 3.4GHz on all cores (if turbo boost is enable) and 3.9GHz single threaded.

The one I listed in my previous post is the correct cooler/part numbers for the HP Z420 workstation.

 

Did you read the review at the bottom of the ebay listing you posted a link to, not exactly positive. I also found this link showing the actual compatibility of the liquid cooler you have listed, i.e. This is for HP desktop PC's, not HP workstations.

As you have the 2013 boot block date, you can install the E5-1680 v2 CPU. It will work with either the standard HP air cooler or the liquid cooler previously mentioned. The v2 CPU also supports 1866MHz RAM.
