Advertised Vs. Real Performance
This is probably the most crucial page, showing how accurate is the data provided by the manufacturers/brands on their products. 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.
Advertised Vs. Real Performance:
- Max Speed (RPM): 2150/ 2288
- Max Input Current (A): 0.16 / 0.16
- Max Power (W): 1.56 / 1.88
- Qmax (CFM): 75 / 70.94
- Pmax (mmAq): 3.15 / 2.80
- Max Noise Level (dBA): 28.0 / 31.1
The claimed airflow is 5.41% lower than the claimed performance, which is not that high. However, this is not the case for the claimed static pressure, where I measured an 11.11% difference. Close to 11.08% is the difference in the maximum noise output (claimed vs. what I measured). There are specific guidelines for taking noise measurements in information technology and telecommunications equipment (ISO7779: 2018), which I follow strictly.

Some fans like the Arctic P12 have overvoltage protection. A lot of other fans don’t though.
hello, thanks for sharing your insight and test on fans… I love this fan… the only issue I have is the ball bearing noise… my questions is: is the noise lower on PWN or DC mode? thanks in advance!!
PWM always, at low speeds. At high speeds it doesn’t make a difference.
