First, I spent 3 hours trying to install KINGPIN into my computer, since I have a top radiator for CPU and 3 front fans. I have to mount the KINGPIN radiator on side. There are two problems I experienced. A bit disappointed for a $2K card.
 

1. The package does not include any mounting screws, I have to use the screws from my case package.
2. The pipe from GPU to radiator is too short, after I mounted the radiator, I cannot install the GPU. I need to install the GPU first then find a place to mount the radiator. As you can see on the picture, it is very close to the top. And I have to remove my fan hub which was mounted on side and reconnect all fan connectors.

 
I simply switch to OC BIOS and start some tests. My setup is built this year.
CPU:                AMD Threadripper 3960X@4.2G
Memory:          128G@3600Mhz
Disk:                Seagate FireCuda 520
Detail:              https://pcpartpicker.com/list/qKdZ9N
 
Installed latest Nvidia driver and Precision X1 1.1.4. Upgraded firmware with no problem.
Port Royal Score: 13769, temp is not reaching 50C, and power is about 420W. https://www.3dmark.com/pr/648874
Time Spy Extreme Score: 11093. https://www.3dmark.com/spy/16385139
DIRECTX RAYTRACING FEATURE TEST: 57.77FPS
 
So far I am very happy with the card.
 

I think if you re-arrange the setup a bit the tubes may reach a bit easier. One to consider is perhaps CPU radiator as intake fans and GPU radiator on top exhaust. You can also try setting LN2 mode it has a higher power target and is still safe to use with stock cooling.

I have close to the same case and the issue is if you are wanting to properly keep the tubes at the bottom of the CPU AIO radiator, it won't reach without inducing a stretch that blocks the GPU.  Just transferring the problem really.  The case is large and 400mm is just a tad too short.  I couldn't vertical mount my GPU either with this radiator placement as it's too tall.
 
Just a downside of this particular type of setup in this case.  It's more for dual system/custom loop.

You think the normal hybrid 240 rad version could reach better? I have your same case.
