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.
Results: Static pressure, efficiency depending on orientation
Explanatory note: The orientation of the impeller can affect the resulting static pressure. In these graphs, we examine the ratio between the “pull” and “push” configurations, effectively producing a coefficient. A value greater than 1.00 indicates that the fan produces higher static pressure when pulling. Conversely, a value below 1.00 means it performs better when pushing. In some cases, the ratio is balanced and close to unity.
