I have absolutely NO EXPERIENCE with this Cooler. And
says its the Best Block in an AIO on the Market, So I would DEFINITELY take his word for it, I have found he has a wealth of great information to share.
That being said, I can share my experience with EKWB's take on this type of cooler. Its 360MM Rad as well, its called the Phoenix 360mm MLC. It uses slightly modified EKWB Parts, and uses Quick Disconnects so you can expand the loop easily later if you want. I am about to expand it with Custom Water loop parts to try to get my 3900x under control with Heavy Loads, but as of right now its only had the 1 360mm Rad and CPU block in the Loop.
This thing cooled Both my 2700x and my 8700k Build Admirably. However, when it comes to my 3900x, it is no where near as good as I expected it. I am pretty sure it comes down to the Block Design not being optimal for the Chiplet Layout, but I was incredibly disappointed with this cooler on my 3900x. During normal Blender Renders, My CPU would reach a Max of 91c in a Room Ambient Temp of 29c. My ambient is obviously higher than most people, so having a more normal 25c Ambient would obviously drop temps by 4 to 5c on what I am getting, but still that Delta was not encouraging. And under the same 29c Ambient with a Workload like Prime 95 Small FFTs or Aida64's FP64 Ray Trace Test, my Temps will instantly spike to 108c as soon as the test starts, and Thermal Reboot at 110c in less than 4 Seconds. (In the Asus Crosshair VII Hero there is no Thermal Throttling at all, instead you get a Instant Reboot once your Tdie temp reaches 110c).
So again, don't take this as a review of the Swifttech Cooler you are looking at, because this is obviously a different product, and appears to have awesome reviews. I would just check to see if someone has used it on the 3900x yet, because some blocks seem to be more optimal for the Chiplet Design than others.
Also, that seller on Ebay is trying to pull a fast one, as others have mentioned, go direct to Swifttech, you will get a better warranty (or warranty at all actually) and it will cost you MUCH less.
