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.
Less than four-degrees out of first is an admirable showing for the X73 with the system at stock settings. We have to admit; we did not expect a two-degree improvement at this level over the X53. We hoped it would do that well, but we also had our doubts.
However, when we applied the overclock, that four-degree gap to first place is now closer to seven-degrees out of first. 72.75-degrees is still decent, but compared to the X53, it has lost some of that gap as well.
If you do not like your ears and want to try running the fans on the X73 balls out, you will soon find that the airflow and pressure are not the limiting factors. Adding a third more fan power to the system netted us a single degree of improvement.
Noise Level Results
During the stock run of testing, we saw that the fans topped out at 1000 RPM and delivered just 27dB to the room. Not the best result on the chart, but still well into the acceptable range for daily usage without it being dominant in the room.
We are okay with the 35dB results of the PWM controlled overclocked test session. The fans were turning at 1400 RPM. Certainly audible at this point, but behind a closed case door, or with a headset on, you will likely not notice it.
To get that last third of power from the fans, we had to enable DC fan control in the BIOS and tell it to drive the fans at full speed all of the time, which has these fans rotating at 2125RPM. It is then that we saw 52 dB on the meter, which is well beyond what most are comfortable with, and there are hardly any gains to be had to do so.
Additional notes to consider: All testing was done with the pump set to fixed mode at 100% resulting in a reported speed of 2777 RPM. Also, relying on my motherboard to do precisely what NZXT intended the fans to do may not coexist. Although, our last test put any of that to rest.
