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 tables below, anything in Red means bad news, while the Blue fonts are good!
Low-Speed Setting
| Performance Metric | Advertised Performance | Real Performance | Difference |
|---|---|---|---|
| Max Speed (RPM) | 1800 | 1875 | +4.17% |
| Max Input Current (A) | 0.35 | 0.31 | -11.43% |
| Max Power (W) | 4.2 | 3.77 | -10.24% |
| Qmax (CFM) | 110.33 | 115.37 | +4.88% |
| Pmax (mmAq) | 2.35 | 2.51 | +6.81% |
| Max Noise Level (dBA) | 39.24 | 42.6 | +3.36 dBA |
Almost every value is better than the advertised, with only higher noise output.
Mid-Speed Setting
| Performance Metric | Advertised Performance | Real Performance | Difference |
|---|---|---|---|
| Max Speed (RPM) | 2300 | 2320 | +0.87% |
| Max Input Current (A) | 0.70 | 0.59 | -15.71% |
| Max Power (W) | 8.4 | 7.03 | -16.31% |
| Qmax (CFM) | 153.11 | 148.41 | -3.07% |
| Pmax (mmAq) | 4.10 | 3.87 | -5.61% |
| Max Noise Level (dBA) | 46.0 | 49.4 | +3.4 dBA |
Power consumption is lower than the max ratings, while airflow and static pressure are not that far from the claimed values.
High-Speed Setting
| Performance Metric | Advertised Performance | Real Performance | Difference |
|---|---|---|---|
| Max Speed (RPM) | 2700 | 2696 | -0.15% |
| Max Input Current (A) | 1.0 | 0.89 | -11% |
| Max Power (W) | 12 | 10.7 | -10.83% |
| Qmax (CFM) | 175.03 | 169.02 | -3.43% |
| Pmax (mmAq) | 5.54 | 5.05 | -8.84% |
| Max Noise Level (dBA) | 50.59 | 52.8 | +2.21 dBA |
Power consumption is lower than the max values that Super Flower claims, which is good; airflow is close enough, while the static pressure is further away from the claimed value. Still, over 5mmAq is a great performance for a 140mm fan. Lastly, noise output isn’t that far away from the claimed value.
When a test of the Noctua IPPC 140mm 3000RPM for have a fan to compare it ? 🙂
Sent an email to Noctua and weirdly enough I didn’t get a reply. Will talk again to my contact there.
