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: Static pressure w/o obstacles
Explanatory note: Static pressure without an obstacle is measured in two different scenarios—using laminar and turbulent airflow at the inlet. The results in this section reflect the first case. This means that airflow to the impeller is laminar, guided through a dedicated inlet tunnel. In such a setup, the fan has access to a larger volume of air, and the resulting static pressure values are higher. This represents the optimal environment for properly measuring fan parameters. For a detailed explanation of what “static pressure” means and how to interpret it, see this article.
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.
