Hey Wendell, I really enjoyed that build vlog because I built a VERY similiar system myself:
3970x + 2 RTX Titans + Aorus Master in the o11 dynamic XL with 3 360 radiators.
I went for full EK too (velocity block).
What are your temperatures like under full load?
My GPUs max out around 52c and my CPU at 84c-ish.
Additional questions:
What are the teslas for!?!?!
Get yourself a second pump - like yesterday, way to much hardware to leave without redundancy.
