The only problems I have with my case are the io plate not compressing the rear io of the gpu correctly (and is a little bit damage, corner has small damage) and that I needed to solder the switch to turn on again, not biggie, as I wanted to braid it. The anodising of my panels is spot on.
Building the loop was the easy part, and the performance is stupid good. For me the only thing that could potentially be improved was ram temps in highly binned b-die sticks at stupid voltage (some of them are going for 1.55v now). Yes, you can raise the Artic P14 of the case to 1200-1400 rpm and have the problem solved as then the sticks will be under 50 C, but that create unwanted noise.
If you have 2 HWL 280 gts with the ports facing to the io shield of the mobo and gpu, and artic p14, you can use this, with 2 noctua na4x20.
With this I have my 3090 pumping 400W, my ryzen 5950x pumping 140W total package, having the temps of the GPU under 60 C, the CPU under 75C on the hotspot (voltage while gaming and streaming is 1.138V, with some jumps to 1.325V, which creates the max temps using CTR), and the RAM around 45C, all of it while running my DDC pump at 1700 rpm, my fans around 950 rpm for the radiators and the 2 small noctua at 2500 rpm out of 5000 rpm, so it is pretty much silent.
As a comparison, my gsync ultimate display has a fan that makes more noise than the whole computer, and you can barely notice it already.
As a last note, if your motherboard has an m.2 on the back, I would recommend putting a small 3mm heatsink on that boy. Not strictly needed, but specially if you have a 3090, it will reduce your temps for that drive around 10-15C while gaming.
After building custom loops in the NCASE, Louqe Ghost and this one, I would take this any day.
