Results: Frequency response of sound with a hexagonal grille
Asus’s efforts in the field of standalone PC fans are on the rise. After the premiere in the form of the ROG XF120, there is now the half-price TUF TF120, which also gives more attractive results in some applications. And that’s even compared to other, similar fans with ARGB LEDs. The geometry of the TF120 is quite sensible, which is why it often beats its competitors in its price range.
Results: Frequency response of sound with a hexagonal grille
Measurements are performed in the TrueRTA application, which records sound in a range of 240 frequencies in the recorded range of 20–20,000 Hz. For the possibility of comparison across articles, we export the dominant frequency from the low (20–200 Hz), medium (201–2,000 Hz) and high (2,001–20,000 Hz) range to standard bar graphs.
However, for an even more detailed analysis of the sound expression, it is important to perceive the overall shape of the graph and the intensity of all frequencies/tones. If you don’t understand something in the graphs or tables below, you’ll find the answers to all your questions in this article. It explains how to read the measured data below correctly.
Fan sound usually operates in the 70–7000 Hz band. You can ignore the 7000 Hz frequencies, they reflect the electromagnetic noise of the measurement chain. This (electromagnetic noise) also extends to frequencies below 70 Hz. These bands (up to 70 Hz and above 7 kHz) could be safely “shaved off”, but we don’t do that. Just in case some anomaly does appear in one of the fans, which needs to be controlled and visualised.

Why is there a missing value sometimes? There may be more reasons. Usually it is because the fan could not be adjusted to the target noise level. Some have a higher minimum speed (or the speed is low, but the motor is too noisy) or it is a slower fan that will not reach the higher decibels. But the results in the graphs are also missing if the rotor is brushing against the nylon filter mesh. In that case, we evaluate this combination as incompatible. And zero in the graphs is naturally also in situations where we measure 0.00. This is a common occurrence at extremely low speeds with obstructions or within vibration measurements.
