I just upgraded my Xeon E5-1620v2 4c 8 threads with an E5-1680v2 8 cores 16 threads and installed the hp liquid cooler for the z420. When I boot I get a beep and an error 513 front chassis fan not detected. I don't have one installed nor had one.. Never did that before. I got one but it's hard to get in with my XL hands. Please advise.

the upgraded config (cpu + water cooling) you have listed comes with the front cooling fan installed to handle the required airflow necessary to cool the inside of the case/add in cards as such you will have to install a front case fan which is rather cheap,...... other option is to downgrade the parts back to the orig setup

"E5-1680v3" won't work in a Z420.... try a E5-1680 v2.
The front fan area is pretty tight, and it is best to take off the Z420's front grill so you can see from the front that the black plastic mating tabs are fitting correctly in their rectangular holes in the front metal as you rotate on those and snap the black plastic fan holder in place. Then, the fan header is way down at the front bottom corner of the motherboard... hard to reach into that corner with the fan plug. Maybe take it to a computer shop.....

There seems to be a cable running down. the front of chassis where the fan should go. see picture. I did not purchase this new. It was a recycled computer from a place that refurbs computers The one on the bottom of the cables I see are different locations and the fan is different than the bulky one..

A Z420 v1 can run a E5-1680 (v1) reliably. A Z420 v2 can run a E5-1680 (v1) and a E5-1680 v2 reliably.
A Z420 v1 or v2 cannot run a E5-1680 v3 or v4. To run those two you need a Z440 level workstation. The v3 and v4 processors have a different form factor and can't fit in the processor socket in a Z420... but they do fit in the socket in a Z440.

one last time,....when you install a high power xeon cpu and the watercooling kit the bios detects both of these and then also looks for the front fan....................which you do not have installed,...hence the bios error
install the fan,...........and all will be well
if you choose not to do this your options are
reinstall the previous cpu
live with the boot error about the fam

Tony, the answer to why I responded with my answer about how the Z420 cannot run a E5-1680 v3 was because your original post on 8/8/20 at 6:23 PM stated:
"I just upgraded my Xeon E5-1620v2 4c 8 threads with an E5-1680v3 8 cores 16 threads..." Bold/underlined is what you had in there originally, and then later after my post you edited that to v2.
Good luck on your project.
