Blades, hub—everywhere there are features disrupting an otherwise smooth design. This kind of detailing defines the HAVN H12 at first glance—and the second impression is just as striking. With the kind of geometry the H12 brings to the table, reaching the absolute top tier is possible. In practice, however, it’s essential to find the right scenarios and fine-tune the right settings to end up truly satisfied.
Results: Cooling performance per watt, static pressure
Explanatory note: Measurements of static pressure at fixed noise levels help determine how efficiently each fan performs under identical acoustic conditions. Since we also record power consumption during these tests, we can determine which fan is not only more effective in terms of cooling but also more energy-efficient. In other words, the data shows which fan produces higher static pressure per unit of power consumed.
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.
