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 the Blue fonts are good!
Performance Metric | Advertised Performance | Real Performance | Difference |
---|---|---|---|
Max Speed (RPM) | 1700 | 1761 | +3.59% |
Max Input Current (A) | 0.12 | 0.12 | 0% |
Max Power (W) | 1.44 | 1.38 | -4.17% |
Qmax (CFM) | 72.8 | 67.04 | -7.91% |
Pmax (mmAq) | 2.4 | 1.86 | -22.5% |
Max Noise Level (dBA) | 10.64 | 30 | +19.36 dBA |
The claimed airflow is within 8% of the claimed value, while the static pressure is far from the advertised. In the noise output section, the brand states that this fan has a max output noise of only 0.3 Sone, which is 10.64 dBA. They did something wrong there since in the P12 PWM PST fan, they also claimed 0.3 Sone. Lastly, the power consumption is even lower than what Arctic states, which is beneficiary for the fan’s longetivity.
The noise info is incorrect for this fan, i almost 20y i have never seen an arctic (case) fan that’s ~10dbA.
its either 19 and up, or, if you go without PWM/CO, the silent (DC) ones do 8dbA (0.08 sone).
The noise I measured is 30 dBA. Arctic indeed provides wrong information in the product’s specs.
