Noise-Normalized Performance Comparison

The CORSAIR QL120 RGB fan is once again the missing entry in the 750 RPM chart, so don't spend much time thinking about that offset above. I do like these graphs, but keep in mind that dBA isn't a linear increase, and simply dividing CFM by dBA is only to be taken as a means to quickly compare the two sets of data collectively—no more than that. Definitely also note that extrapolating data across individual numbers comes with an asterisk next to them. Regardless, Phanteks obviously has done what many others have tried by deposing the Noctua NF-A12x25 from its throne after a 3-year reign. The Phanteks T30-120 is one of the very few fabs that gains in strength relative to others as you go from 750 RPM to 1500 RPM, with the relative gap increasing the faster you go. This is where the increased fan blade height—or depth depending on how you look at it—plays a major role in pushing more air through at not only the same fan speed as seen on the previous page, but also at less added noise output than the increased airflow.
