Antec Storm 120: Efficient in the middle price class

After many years, we finally managed to get our hands on the Antec Storm 120. That is, 120 mm fans combining an attractive (and efficient) geometry with good price accessibility. Although these are not outright cheap fans, the price is still relatively low. The result is quite appealing. Don’t look for technical perfection here, but “for that kind of money” it is good. Especially if you also value other things than the price/performace ratio.

Results: Frequency response of sound with a hexagonal grille

Measurements are conducted using TrueRTA, which captures audio data across 240 frequency bands within the 20–20,000 Hz range. To facilitate comparisons between articles, we extract and present the dominant frequency from each of three spectral bands: low (20–200 Hz), mid (201–2000 Hz), and high (2001–20,000 Hz) in standardized 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 any aspects of the graphs or data tables are unclear, detailed interpretation guidelines are provided in this article.

Most fan-related acoustic activity occurs within the 70–7000 Hz range. Frequencies above 7000 Hz typically represent electromagnetic interference from the test environment, while the lowest bands below 70 Hz may also include such noise, albeit mixed with aerodynamic sound. Although we could exclude these frequency extremes, they are retained to detect and visualize potential anomalies.

Why is a value sometimes missing for a fan? There can be several reasons. Most commonly, it’s because the fan couldn’t be regulated to the target noise level. Some fans have higher minimum RPM (or they spin slowly but have an excessively noisy motor), or they are simply slower models that can’t reach higher decibel thresholds. Results are also omitted from graphs if the impeller scrapes against the mesh of a nylon filter. In such cases, we classify the combination as incompatible. And of course, a zero in the graphs naturally appears in situations where we record an actual 0.00. This often occurs at extremely low speeds when obstacles are present or during vibration measurements.

  1. Next up will be ID-Cooling… with one aerodynamic feature that none of the fans we’ve tested so far make use of. 🙂
