@SecurityWriter In my opinion only custom watercooler are a bit better than air cooler regarding noise and cooling. But custom watercooler are expensive and you need some experience. Also a case where everything fits or using an external watercooler like MORA. AIO are crap, expensive and not as quiet like air cooler. Noctua dh15 is much more quiet than most aio and the cooling is excellent. Currently I am using a SFF case with Noctua NH-L12Sx77 and 5900x cpu.Noise and cooling ok
