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) | 2400 | 2432 | +1.33% |
| Max Input Current (A) | 0.50 | 0.31 | -38% |
| Max Power (W) | 6.0 | 3.67 | -38.83% |
| Qmax (CFM) | 97.41 | 100.57 | +3.24% |
| Pmax (mmAq) | 3.64 | 3.27 | -10.16% |
| Max Noise Level (dBA) | 36.8 | 39.4 | +2.6 dBA |
Speed and airflow are higher than the claimed values, but this is not the case for static pressure, which is 10% lower. Noise output is also a bit higher than what be quiet! states, but a difference lower than 3 dBA is not that high. Or, to put it better, I have seen way higher deviations in noise measurements.
Hi!
Thanks for the very cool and high-quality reviews, no one else does that.
I want to ask you to test noctua nf-a14, a new generation model will be released in the 2024q1, it would be cool to compare
Once it is out, I will definitely test it!
So basically they lost in what was meant to be their niche of static pressure across the board to a cheaper rgb fan? 😂. Even more embarrassing is in Australia where these are about $65 aud where the shark’s have dropped to $25. Either way ur testing is invaluable for these more niche products especially, cheers.
