The results of our testing can be seen in the following table and diagram:
The NZXT Kraken X60 boasts impressive performance. Even at the minimum speed of its fans (800 RPM) it is as good as the Corsair H100i Extreme Performance at the maximum speed (2670 RPM) or as the Swiftech H220 at 1200 RPM. And it is a mere 1°C worse than the NZXT Kraken X40 at 1870 RPM. As the speed of the Kraken X60’s fans increases, it becomes unrivalled in performance so that the peak temperature of the hottest core of our overclocked six-core CPU is not higher than 60°C! That’s an outstanding result. At the maximum speed of its fans the Kraken X60 is 6°C better than the X40, 7°C better than the Corsair H100i Extreme Performance, 5°C better than the Swiftech H220 and as many as 9°C better than the best air cooler Phanteks PH-TC14P?.
Then we checked out the NZXT Kraken X60 with our CPU overclocked to 4.5 GHz at a voltage of 1.435 volts. Here's a table with results and a diagram too:
The NZXT Kraken X60 is even more confident with the hotter CPU. The Corsair H100i Extreme Performance manages to get closer by 1°C, yet the gap is still large at 5°C. The difference from the Swiftech H220 hasn’t changed whereas the NZXT Kraken X40 and Phanteks PH-TC14P? lose 9°C to the leader. The coolers are closer to each other at the minimum speed of their fans, but the Kraken X60 is still ahead by 3 to 6°C.
That’s not the best the Kraken X60 can do, actually. We tried to check it out at the highest frequency of our CPU (4.625 GHz at 1.49 volts) and found it capable of keeping the CPU stable at 1000 RPM or 1820 RPM.
NZXT Kraken X60, 2x1020 RPM
NZXT Kraken X60, 2x1820 RPM
The peak CPU temperature was 74°C in the quiet mode and 72°C at the maximum speed of the fans. That’s impressive even though we ran our tests on a semi-open testbed. Now let’s see how noisy the Kraken X60 is.
