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 follow the specific guidelines (ISO7779: 2018) for taking noise measurements in information technology and telecommunications equipment strictly.
In the table below, anything in Red fonts means bad news, while the Blue fonts are good!
| Advertised Performance | Real Performance | Difference | |
|---|---|---|---|
| Max Speed (RPM) | 2500 | 2461 | -1.56% |
| Max Input Current (A) | 0.45 | 0.44 | -2.22% |
| Max Power (W) | 5.40 | 5.26 | –2.59% |
| Qmax (CFM) | 100 | 94.18 | -5.82% |
| Pmax (mmAq) | 4.66 | 4.07 | -12.66% |
| Max Noise Level (dBA) | 41.2 | 45.4 | +4.2 dBA |
The difference in static pressure is high, while in airflow, it is notably lower but still above 5%.
