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.
Please compare the Super Flower Megacool 140 to the Iceberg Thermal Icegale Xtra 140 and the Noctua iPPC 140.
Noctua was supposed to send this fan, but they didn’t eventually. I guess they are pissed with the G2 review.
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.
