We measured the noise level of each cooler throughout the entire speed range of its fans. Here are the results:
The two 140mm NZXT Kraken X60 fans are expectedly noisier than the single such fan installed on the Kraken X40 and also louder than the Corsair fans. Only the original Phanteks fans produce more noise, the speed being the same. On the other hand, the two NZXT FX-140 fans aren’t noisy by themselves at 850 RPM. They are not uncomfortable then and, as we learned above, this speed is enough to ensure proper cooling for a six-core CPU with enabled Hyper-Threading at high clock rates and voltages. The pump of the Kraken X60 is virtually silent.
The Swiftech H220 is deservedly the quietest cooler in this test.
We guess the only downside of the NZXT Kraken X60 is that it has limited compatibility with computer cases which cannot generally accommodate its 240mm radiator. Otherwise, the Kraken X60 is the best ready-made liquid cooling system even considering the price factor. It is compatible with all modern CPU platforms and easy to install, so it can be easily deployed even by inexperienced users. And its high performance (for its class and price) is going to satisfy even the most demanding overclockers. The Kraken X60 is extremely quiet at the minimum speed of its fans but retains good performance then, as we made sure in our tests. And you can even attach as many as four fans to it!
The Kraken Control software should also be mentioned as it allows to monitor key system parameters and regulate the speed of its fans and the color of the water block glow. Thus, the NZXT Kraken X60 is the perfect entry-level liquid cooling solution if you can find a computer case to fit it into. It even delivers too high performance to be viewed as just entry-level. That’s why we recommend it for any user who’s interested in coolers of this kind.
In conclusion we are proud to award NZXT Kraken X60 our Editor’s Choice as the best mass production ready-to-go liquid-cooling system:
