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%|
|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%.
