stability test, encode a 3hr long 4K movie in 1080p H.265 while I'm doing other stuff lol
had to crank up the fans to max and even like that the H115i AOI is struggling (90°C)
if gaming doesn't completely ruin my thermals I might keep the build as is as the fan noise at max isn't too bad
edit : finished ! well you don't need heating with those cpus lol I'll have to wire one of the MB heat sensors I've never felt an AIO get so hot to the touch
oh boy encoding with the cpu may free the GPU to only do the gaming (which for heavy games using 90% gpu by themselves is a good thing, borderlands 3 in ultra is one)
but oh boy I just tried using nvenc to do the same job with the 1080Ti and my encoding fps doubled O_O

Man I wish I had the cash to purchase one of these CPUs with all the ripping of media that I am doing for my family's personal Plex server I could use the extra cores and threads for running a ripped blu-ray file through handbrake to decrease the size of the file.

feedback from my latest re-re-rebuild
I dumped my "precious" all-rgb fans everywhere and good looks for something that looks like a pimped out behind-the-scenes machine plumbing, it looks akward to say the least
but...
it now runs 4.4Ghz @1.4v all cores ! @80°C (with MSI motherboard OCGenie10 overclock preset, there's a "11" @4.45Ghz but it doesnt even boot)
and what's weirder...it draws a ton less Watts, like 60 less ! weird or not as DerBauer explained that in one of his oc Ryzen videos, the more heat the less efficient it is the more heat it generates, a vicious cycle
I've got 3x silent wings 2 on a 360x30mm rad + 3x silent wings 3 hi-speed pwm on a 360x55mm rad lol and that on a Corsair hydro x cpu block not covering the whole cpu package (zero availability here for good blocks like the heatkiller) but anyway, didn't waste my time, I not only didn't run oc before I actually underclocked and volted it 4.15@1.24v, don't need to do that anymore

pro-tip for watercooling :
- rads should always be case intakes, it makes a massive difference 5-10°C easily, the degrees you gain from cold outside air make the water temp colder and so your cpu colder and so all your rad is going to exhaust is almost-cold air my rads are cold to the touch now if you intake case air through your rads it's going to be the opposite hot = more hot = more hot = bad result (my h115i aio that was top mounted was noticeably hot)
- never place a rad on the top, never ever....if you don't watercool your gpu (and even if you do) because you'll be "cooling" your cpu with 60+°C air coming out of your gpu backplate, you can see that in various videos like Bitwit youtube.com/watch?v=xNAMxZgvves

Protip for overclocking Ryzen: Watercooling does not help much for overclocking Ryzen

I got the same "same" result with the stock cooler for 3900x VS custom Ek water cooling with 2x 360 radiators :p I gained maybe 25mhz all core overclock. The biggest gain was the Decibel of the coolingsystem Crazy load vs pretty much silence.

Using Asrock x570 Taichi and 3900x.

I guess that depends on whether you prioritize your CPU or GPU, and how the loop is configured overall. Case intake is great for water-cooling the CPU but will be a detriment to air-cooling the GPU (and vice versa). If they're both water-cooled and on the same loop then it probably won't matter either way.
