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.
