It's too bad they don't sell this one in a non-RGB puke form (or at least non-RGB fans) as this seems like a great cooler. The only light in inside my case is the EVGA logo on my video card and I'd like to keep it that way.
One thing you could consider doing is checking the cold plates on the coolers to see if they have a bump to get extra performance. This is mostly academic without long term testing, but some of the cheaper models that's basically what they did. I think Asus also did it with at least one of the Ryujin coolers.
Looking forward to the new year for coolers though as hopefully the new Hyte AIOs will hit and Thermalright has listed the Royal Pretor 130 on their site so I'd assume retail availability will be soon.
I'm waiting until Intel publicly states yay/nay on more LGA 1851 parts before picking a new AIO. While I don't need it at all now I'll probably get a new video card at some point which won't have it's own AIO at which point I would.
