Price History (Excluding Tax & Combo Deals) History:


Even though I already knew how to install it, the installation instructions were terrible.

The software was terrible. I could not even change the colour of the pump LED. Luckily, NZXT had just posted a beta of their next software to dropbox.com 42 hours BEFORE I hit the technical support forum, which solved the problem.

And, the pump is already making noises. I can hear it grinding from across the room in bed.

NOT impressed.

from completed build 5930K Build

Phenomenal performance for an AIO, at 4.5Ghz on all 6 cores for multiple days with power management allowing all 6 to run max speed non-stop, the Kraken X61 kept idle temps in the 40s C and max temp under stress testing at 80C.

from completed build Deep-Blue

this is my first all in one cooler.

i found it easy to install . the CAM software that operates the system i found easy to use.

just running normally the temps sit around 15'c

underload it has gone up to about 55'c

the computer sit on top of my desk and has unrestricted airflow

from completed build Cerberus

Originally bought a Corsair H105, but swapped it out for this nifty little piece of tech. While this keeps my CPU ever-so-slightly cooler, it is more importantly quite noticeably quieter. The ability to change the color of the lights is a god-send, but the CAM software is somewhat of a let down.

Overall very pleased so far. Probably on par with high end air coolers, but definitely no custom loop competition. Five stars because I find it hard to imagine a similar AIO performing better to any large degree, but I have not personally tested any others.

from completed build Vulpes Vulpes

Works pretty well, but as with the grid+, the software kinda sucks.

Although this may not be the most popular choice for an IAO, I really like it, and it cools with the might of a thousand angry snowmen. Unfortunately, the installation was... only just acceptable. I watched an installation guide on youtube that was absolutely no help at all (I won't name names), and even NZXT's own youtube instruction video just glossed over the part I was stuck on (coincidentally, the reason I was stuck was because of faulty instructions from the first video). But it was over quickly and it was all worth it. Matched perfectly with the Noctua fans. The CAM software is very good, actually. I like it; I'm not sure what everyone else is going on about. It's good looking and easy to use now (there was probably an update). There is even a handy dandy FPS meter which is fully customizable to display whatever you want (e.g. RAM usage, VRAM usage, CPU/GPU temps and load, and obviously FPS with lows, averages, and highs). As a side note, there were a few bent fins on the radiator itself out of the box D': This sort of upset me but I'm sure the performance is not really affected. Sorta gives a dirty look at NZXT's quality control though.

from completed build Dark Knight

A very quiet cooler. Not compatible with the Zalman Z11 Neo case without some modifications to the case (see my Dark Knight Build).

from completed build A Tribute to Jipster

Beautiful cooler, wish it would be in form factor with the case, but besides that, great and worth it more than the h110i gt

from completed build Dual 980 Ti Hybrid Extravagance

The NZXT Kraken X61 is a fantastic cooler - easy to assemble, remarkably powerful, and quiet (if you want it to be). So why not 5 stars? Honestly - NZXT's documentation and packaging leaves a lot to be desired. This is a premium product; it deserves a lot more than a flimsy cardboard holder and a poorly-printed instruction sheet. Thankfully, the online instructions are much better and the CAM software is working beautifully for me.
