Low price also applies when it comes to the Stratus 140 White ARGB fans. Considering the presence of vivid ARGB lighting, there aren’t many cheaper models in the 140 mm category. Its excellent aerodynamic characteristics are held back by one thing only, and that’s higher vibration levels, and it doesn’t appear to be a “one‑off sample issue”—as usual, our detailed testing is based on multiple units. Still, the trade-off seems to be worth it.
Results: Frequency response of sound with a radiator
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.
Note: These tests are performed using a thinner 28 mm radiator. This thickness—along with the 22 FPI density—is typical for practical applications, including AIO liquid coolers.

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.
