Temperatures do not drift over an all night load
You are paying a lot for the screen
This sits on a machine that runs long simulations overnight, and it has never once been the reason something went wrong. The thing that justifies the money for me is thermal consistency. Hour eight of a load looks the same as hour one, no creep, no fans ramping up as the coolant warms through. Whatever they have done with the pump and the cold plate, it holds. The fans have been quiet the whole time and the pump has stayed silent, which for a closed loop after two years is not something I took for granted. If you want it purely for the screen it is a very expensive screen. If you want a cooler that does not drift, it earns its place!
Used for: 3–6 months
Useful screen, effortless cooling
Needs the ASUS suite installed
The screen showing coolant temperature has become something I check without thinking. Cooling has been effortless the whole time!
Used for: 1–3 months
Machined metal block and properly weighted fans
Build quality is exactly what the price implies. The block is machined metal rather than plastic, the tubing is properly sleeved, and the fans have a weight to them that cheaper ones do not. On a 285K under a full load it holds the low eighties with the fans nowhere near maximum, which is all I wanted from it. A month and a half in, nothing has changed.
Used for: 1–3 months
Silent pump and lighting that matched my other ROG parts
The price is difficult to defend
It has been utterly faultless. The 360 rad in the roof cleared everything, the ARGB matched the rest of my ROG parts without any fiddling, and the pump has never made a sound.
Used for: 1–3 months
Clip on bracket makes fitting easy
Screen defaults are dull until you configure it
Installation was easier than my last cooler, largely because the mounting bracket clips on before you lift the block into place. Cooling and noise have both been excellent since!

Genuinely silent pump and a superb screen
Armoury Crate is heavy and wants to run everything
This went into an air starved little case and the results are better than I feared. The SLC screen is the headline feature and it is very good, but the part that impressed me more is the pump. It is inaudible. I put my ear against the block expecting the usual faint whir and got nothing, which after two previous AIOs that hummed is worth a lot, and three weeks in it has stayed that way. The grumble is Armoury Crate. To do anything interesting with the screen you install a suite that wants to manage every ASUS product you own, and it is heavy and slow. The cooling and the hardware deserve five stars; the software drags it down!

A pump screen that is genuinely readable and useful
The Ryuo sits on a 9950X3D here and the screen on the pump head is the first one I have owned that I actually look at. It is bright, sharp and big enough to read from the desk, and it shows CPU temperature and clocks without me opening anything. Cooling is what you would expect from a good 360, holding the high seventies under a long render. Twelve days in and I have no complaints at all.
Used for: 6–12 months
The cooling hardware itself is beyond criticism
Software updates keep breaking the pump screen
I have gone from delighted to grudging over nine months, which is not where I expected to be at this price. The cooling is fine. Never a bad temperature, never a noise from the pump, and the fans are well behaved on a sensible curve. Nothing wrong with the hardware at all. The problem is everything around it. The screen needs the ASUS software running to show anything other than a default, that software has updated itself four times since I fitted it, and twice an update has left the screen blank until I reinstalled. Once it reset my fan curve as well. For a cooler that costs more than most graphics cards I expected the software side to be as solid as the metalwork, and it simply is not.

No performance drop after more than a year
Software is still a nuisance
Hard use throughout and the loop has not lost a degree of performance. Still silent, still holding a hot chip in the seventies during long sessions!
