Advertised Vs. Real Performance
This is probably the most crucial page, showing how accurate the data provided by the manufacturers/brands on their products is. Since nobody so far could verify these numbers, it was an open field for every brand to declare whatever it wanted, but this stops now. I should also note that I strictly follow the specific guidelines (ISO7779: 2018) for taking noise measurements in information technology and telecommunications equipment.
In the table below, anything in Red means bad news, while the Blue fonts are good!
Performance Metric | Advertised Performance | Real Performance | Difference |
---|---|---|---|
Max Speed (RPM) | 1600 | 1581 | -1.19% |
Max Input Current (A) | 0.2 | 0.17 | -15% |
Max Power (W) | 2.7 | 2.1 | -22.22% |
Qmax (CFM) | 59 | 53.41 | -9.47% |
Pmax (mmAq) | 1.8 | 1.27 | -29.44% |
Max Noise Level (dBA) | 27 | 30 | +3.0 dBA |
The max speed is a bit lower, and power consumption is also lower than advertised, which is good. In performance, both airflow and static pressure are lower than the advertised. The deviation is below 10% in airflow and close to 30% in static pressure, which is a vast deviation.
