"You don't need a liquid cooler for a locked CPU"; I frankly love the way this cooler looks, as well as the fact it is far more quiet than the air cooler equivalent. It is far better performing than the biggest tower cooler I can fit in my case, albeit a little on the expensive side. The LEDs look absolutely stunning. Variable pump and fan speed are unique and keep the noise down very well.

This is a Great looking cooler, the mirror finish on the pump is very nice and the RGB effects are great!

Looks cool and you can see the block through the top or back depending on how you set things up. The LEDs are nice but there's not much of a point to them since you'll only see it standing over the case. Lets you control pump speed and fan speed separately. Sounds like a waterfall when you run it for the first time but this is normal and expected. Detachable USB and fan cable are a big plus; I had to RMA my X61 because the fan cable broke so this is a welcome addition.
Haven't tried the stock fans so I can't comment on those. Pump noise is inaudible over everything else in my system, though.
Runs hotter than I'd like, but maybe I'm just too used to the X61. Idle liquid temp is ~39C after sitting on the desktop for a bit, and load liquid temp is ~45C max. That's fine, but the CPU idles really high despite reseating it 4 times (will make that 5 shortly). CPU idle is ~50C avg (yikes!)

I really thought I wouldn't be able to say that a $115 140mm AIO is worth the money, but it is. As used on a 7600K at 4.4GHz allcore, putting out about 75W of heat at max load, it is SILENT, not only at idle but even after running Prime95 for more than an hour. Granted, this is with a Noctua fan that tops out at 1200RPM and it comes with a temperature of about 80C under said stress test, but that's still impressive (and very useful to me). You might say that any air or water cooler can do this with the right fans and fan profile, but here's the important bit: you can use a temperature curve based on liquid temperature, which means that the fan and pump speeds go up nice and gradually, don't react to sudden spikes in CPU temperature, and aren't affected by bad CPU thermistors or bad thermal capacity of the CPU itself (e.g. Intel's thermal-pasted heat spreaders). And yes, I have tested, and my idle and load temps are both roughly the same when using a liquid temp-based curve as they are when using a CPU temp-based curve. What's more than that, with low-voltage fans and the right amount of splitters, you can slave all your case fans into NZXT's software with just this one cooler, making them all that quiet and nicely reactive AND able to be controlled in Windows rather than jimmying with BIOS fan controls.
Beyond those functionally attractive qualities, there's the obvious aesthetics, which 100% live up to the hype. The infinity mirror pump head and its massively customizable LEDs are simply unmatched by anything else on the market right now and you do not get tired of looking at them.
