It has exactly the elements that make an inexpensive fan aerodynamically efficient and acoustically unobtrusive. Or rather, not too obtrusive—at least at lower, non‑high speeds. At higher speeds, every fan is “noisy,” but making a low‑cost fan that can still be described as pleasant to the ear is already something of a feat. We can, however, state that ID‑Cooling has achieved this with the AM‑120‑K model.

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.
