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 could verify these numbers so far, 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) | 3000 | 3089 | +2.97% |
| Max Input Current (A) | 0.31 | 0.35 | +12.9% |
| Max Power (W) | 3.72 | 4.24 | +13.98% |
| Qmax (CFM) | 97.82 | 95.61 | -2.26% |
| Pmax (mmAq) | 5.13 | 4.96 | -3.31% |
| Max Noise Level (dBA) | 36.63 | 41.6 | +4.97 dBA |
Power consumption is notably higher than advertised. Performance-wise, both airflow and static pressure are not far from the claimed values. Lastly, the noise output difference between the advertised and the reading I got in my hemi-anechoic chamber is high, with the following noise floor.
