The Justice II looks like it delivers a sad result, but the reality is that 61-degrees is not all that bad. However, the NiC C5 was in the charts with the Justice, and it beat the C5. The Justice II is a couple of degrees behind the C5 this time around, so we do get less performance this time around.
At 77.5-degrees, we are over eleven degrees from the top of the chart. Again, not a horrible result as we are still quite a ways away from the throttle point of this processor, and have more room to go if the CPU has more left in the tank.
The 73.75-degree result is not so important here, as it is our metric to see what sort of performance they left in the cooler opting to go beyond the PWM fan curve. In the Justice II, without much of a noise increase at all, we were able to get nearly four degrees of performance increase from this cooler with little effort or irritations from opting to go this route.
Noise Level Results
While the PWM circuit is in use, the lowest we saw the fan spin was at 450 RPM, and at this point, we guarantee it will not be heard inside of a case. While running the stock settings for the CPU, the highest speed we saw in software was 650 RPM. 26 dB is all we got from the fan at that speed.
As we changed over to the overclocked profile in the BIOS and ran the test, the fastest we saw was 840 RPM for the fan. At this time, we got to a whopping 28 dB of noise level, so they are under the radar for most ears out there.
We do wish that Reeven had been more aggressive with the fan curve. As out OC testing shows, they left almost a quarter of the fan's performance in the tank, not even trying to use it. Since the fans noise level only increased to 33dB at full speed, we feel they would have been better served to opt for a bit more performance under control of PWM.
