The first ID-Cooling fan in our database, and it immediately features one unconventional element—the blade ring is positioned differently than usual. Its placement bellow the blade tips is typical of high-speed fans, and the AT-120-K model indeed spins at very high speeds. Despite that, it can also be significantly slowed down while maintaining attractive cooling efficiency even at lower noise levels. And all of this comes at an attractive price point.
Static pressure per euro
Explanatory note: The following charts present static pressure output in relation to unit price. This cost-performance coefficient is calculated by dividing measured static pressure (in mm H2O) by the fan’s price (in EUR), then multiplying the result by 1000. This is specifically to prevent the resulting values from starting with unflattering zeros.
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.
