An interesting quandary. Comparing two fans of the same dimensions. One with what I consider to have rather predictable performance stats while the other seems something between a mystery and a falsehood, given how they choose to advertise their product. (Slim fans in particular, as their potential use in a specific case requires half the 30mm depth of most case fans.)
With fan noise (<21dB) almost always being my most primary concern (non-gaming usage). Vendors posting noise factors in Sones both puzzle and irritate me.
Case and point:
1) Scythe Kaze Flex II 120 Slim PWM -Maximum Noise: 23.9dB, Max. Speed: 1500 RPM, Airflow Capacity: 39.44 CFM
2) ARCTIC P12 Slim PWM -Maximum Noise: 0.3 Sones ( equivalent to 10.64dB ) , Max. Speed: 2100 RPM, Airflow Capacity: 41.1 CFM
* Is one of them less than honest about the performance of their product?
* Or could such disparity be authentic?
* Or am I simply observing the difference between a high static pressure fan and a simple high airflow fan? (Differences that some vendors may not want to heavily emphasize to limit their marketability.)
