@justsimple88, welcome to the forum.

Here is the Maintenance and Service Guide for the workstation.  On Page 21, it tells the processors that are compatible with the motherboard; 

Intel Series C602 chipset:

● Support for the Intel Xeon Processor E5-1600 Series and E5-2600 Series, including processors up to 150 W

● Integrated 4-channel memory controller

● Microarchitecture improvements

● Large L3 cache for superior performance

● Intel QuickPath Interconnect (QPI) connects processors and I/O controller with speeds up to 8 GT/s HP Liquid Cooling option is available for all Z420 processors a nd is required on the E5-2687W processor model.

The Guide will have any other information that you need, also.

Read this post,  HERE.

You understand that you have a v1 Z420 rather than a v2 Z420 with the newer of the two boot block dates of 3/6/13.

Yours can only run the processors listed in the earlier QuickSpecs for the Z420..... download a bunch of those and when you see processors that are Intel V2 you'll know you can't run those.  Processors listed in the early QuickSpecs may not be listed in the later ones but they'll still work.

Your heatsink/fan can run the cooler or hotter running processors, which is nice.

There are lots of posts in here about upgrading the Z620 to faster processors and you'll be able to get perspective from those posts.....
