Chad's CPU Cooler Test System Specifications




To see our testing methodology and to find out what goes into making our charts, please refer to our CPU Cooler Testing and Methodology article (October 2016) for more information.



Thermal Results




The CPU is at stock speed, and we are using the motherboard's PWM setting to allow CAM to read it for its settings. In silent mode, the Kraken X62 is the third best cooler at 55.25 degrees, but when put into performance mode, it takes top honors in our chart at 52.75 degrees.




At this point, we do have the overclock applied, but PWM is still sending signals to control speeds of the fans and pump. Setting the X62 to silent mode, we saw a mediocre result of 72.5 degrees. Good, but not great. However, once we moved to performance mode, the Kraken jumps ten spots, making it the second-best cooler we have tested on this 6700K.




Even with a bunch of noise involved, the Kraken X62 holds its ground and stays in second place. While 67 degrees is nothing to laugh at, we would have hoped to see it beat the smaller H80i.



Noise Level Results




Silent mode has the fans turning at 489 RPM, giving us the 24dB rating. In performance mode, the fans increase speed, but to just 800 RPM, and are still quiet at just 25dB




With processor overclocked the fan speed increases slightly in silent mode, and we took a 25dB reading then. Even in performance mode, the fans increase is speed under 100 RPM, but the noise level rose slightly here too, to 26dB.




The fastest we saw the fans running in the CAM software was at speeds of 1864 RPM, and boy, do they bring the noise, in the tune of 76dB. We also took account that the pump is now spinning at 5387 RPM as reported by CAM software, and if you turn the fans down, you can hear the pump.
