Now that’s what we call a turnaround. Remember how the BioniX F120 failed on obstacles? The newer BioniX P120 (A-RGB) no longer has such a fundamental limitation. On the contrary, it is significantly less stifled by obstacles than many competing fans. Just tame those vibrations, fine-tune the acoustics, where there are some flaws, and it’ll be great. The basis (the rotor) is better in practice than the label parameters suggest.
Reality vs. specifications
Explanatory note: For a quick overview of how manufacturers “spice up” specifications, we have a sort of “truthfulness” coefficient. We calculate this by putting our measured values in proportion to those given in the specifications by the fan manufacturers. A result of “1.00” means that the claimed parameters match the values we have recorded. After such a finding, we can conclude that the manufacturer has done his job honestly and the way he presents the fan agrees. The more the coefficient number is different from 1.00, the less accurate the claimed specifications are. Of course, the better case for the user is if the coefficient is higher than 1.00 (and it is, for example, 1.20), then the real parameters exceed the paper ones. Conversely, if the coefficient starts with zero, then the fan does not reach the parameters on paper. For example, a value of 0.80 means that the real airflow or static pressure is 20 % lower than the manufacturer claims.
