High performance components often come at the cost of high heat generation. The NZXT Kraken X61 RL-KRX61-01 CPU liquid cooling solution delivers outstanding cooling performance to keep your component running in top gear and away from dangerous heat build up. It employs 280mm radiator, two new FX 140 V2 fans, CAM connectivity, durable tubing, and a powerful variable speed pump to meets your cooling needs. The all-in-one design makes setup a breeze and reduces the maintenance to the minimum.

Features:

The 280mm radiator platform gives 36% more surface area over comparable 240mm coolers.

State of the art high performance variable speed pump.

High pressure, micro-fin copper coldplate.

Integrated Hue and digital fan control with CAM connectivity.

Two newly designed FX140 V2 performance liquid cooling PWM fans tuned for static pressure.

Large tower support with extended 16” tubing makes installation a breeze.

Premium black sleeved cables for a clean look and improved airflow.

Pre-installed Intel mounting for easy block mounting.

Bad

Pros: worked for a while?

Cons: The software has always been buggy to us at least. Installed two of these on my and my wife's rigs as we built same time same rig. Fans failed on mine with in maybe 6 months, no biggie, plenty of fans around here. Now her pump went out. 16 months. We clean our systems often, these failures should not be occurring. Meanwhile stock case fans are whirling away. No worries NZXT its just a CPU COOLER. Will not purchase a cooling solution from this manufacturer again.

Not as quiet as you'd expect (water pump)

Pros: -Easy way to achieve liquid cooling

Cons: -Fans are quieter than the water pump, though still quieter than air cooled
-Installation instructions could be clearer
-CAM software is kinda clunky (doesn't always load on login, gives little guidance on setting temp thresholds for alerting)
-Not sure the plug that goes to the CPU FAN header works right. I get a CPU fan error in the BIOS, but the CPU runs within temp specs, so I'm assuming it's just not giving my board the input it's looking for. (ASUS ROG)

Other Thoughts: I was pretty anxious about trying this, I wasn't sure I'd verified everything was working ok. Several months in, it's been running like a champ.

I've lost all faith in NZXT's development team

Pros: Fantastic liquid cooler design, durability, and features.
Quiet
Intuitive installation instructions (including animations on their webpage)

Cons: The fan controller (CAM) bundled with Kraken is buggy enough to cause the cooler to not function. See other for a workaround.

Other Thoughts: It's not that NZXT is a bad company. Their support team is very responsive. The real problem that I and several other component owners have is the software development path they're taking.

Instead of fixing bugs (i.e. crashing intermittently, failure to detect Kraken, crashing due to overlay problems), NZXT's CAM development team focuses on new features, some of those features that have no place in a fan controller program.

When CAM isn't running, only ONE radiator fan continues to spin. On a couple of occasions, my computer has shut down entirely because the CPU has gotten too hot.

I've addressed this issue with NZXT's support team, and was promised a stable release in the future.

However, there is a workaround. Everything w+ill be fine if you're willing to route the fans to be controlled by your motherboard or some other fan controller.

Great cooler, terrible fans.

Pros: -Easy to install.
-Sleeved cables.
-SATA (not Molex) power
-RGB

Cons: -Fans are VERY loud. They work they are just incredibly loud. They are even louder than my blower-style card at 100% power. Not docking much for it though as this is easily fixed with 3rd party fans.
-Pump sometimes makes some "gurgling" noise. Not audible though unless you REALLY look for it. Might also just be my unit.
-Tubes are kind-of long. Could be a plus for some but I'm not using a very big case, so yeah.

Other Thoughts: I would recommend, but throw away the fans it comes with and get some better ones from another company.

Keeping it cool

Pros: Seems solid and keeps my i7-5820k cooled enough for a stable to overclock at a comfortable 4G (but I'm not a pro- so I haven't needed yet to go higher.)

Cons: I found the setting so it flashes different colors, but haven't found the setting for them to fade. Perhaps there is one and I haven't found it yet.

Other Thoughts: I like that you can change the colors of the internal LED and it looks great in my window case. But, I was thinking that it would be nice if the colors could fade into eachother.

failed after 4 months

Pros: worked well was quiet and kept cpu cool overclocked to 4.4ghz
looks pleasant compared to deepcool and corsair coolers
better than air cooler

Cons: poor placement of stickers directly over nzxt logo, left residue when peeling off.
sudden failure of pump. confirmed by turning all fans off and pump makes a loud grinding noise.

Other Thoughts: i would recommend this product for cooling and features but falure rate does seem high on these for quick googling. would give 5 out of 5 but has failed soe 2 eggs is appropriate.
