Thanks for the replies folks. Different opinions are not always a bad thing and we certainly have a few here. I will say that my custom loops have always been quieter than any AIO I have ever used, it’s been ages since I actually used one. I have read good things about the one I mentioned as well as the newer Corsair H115i Platinum and these were the direction I have been leaning. Still interested in hearing more people’s experiences with AIO’s and the 9900K. The particular CPU I ordered is binned for 5GHz at 1.300V, AVX 2 so I imagine it has a little more headroom there if I ever wanted to go past 5GHz but I can’t imagine I will. Currently my 7700K at 5.1Ghz rarely breaks 50C under load. Well, my normal use case load, not any form of stress test. That is my comparison.
