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 blue is good!
| Advertised Performance | Real Performance | Difference | |
|---|---|---|---|
| Max Speed (RPM) | 3000 | 3032 | +1.07% |
| Max Input Current (A) | 0.3 | 0.36 | +20% |
| Max Power (W) | 3.6 | 4.37 | +21.39% |
| Qmax (CFM) | 83.9 | 83.15 | -0.89% |
| Pmax (mmAq) | 5.31 | 4.91 | -7.53% |
| Max Noise Level (dBA) | 36.9 | 42.6 | +5.7 dBA |
Power consumption is notably higher, while airflow is very close to the advertised reading. Static airflow is a bit further, and noise output is significantly away from what I measured. Most users will perceive a close to 6 dBA difference.
