Fractal Design Dynamic X2 GP-12 PWM vs SilverStone FQ121: Comparison
Fractal Design Dynamic X2 GP-12 PWM vs SilverStone FQ121: the airflow difference
Airflow is where these two genuinely part company, Fractal Design Dynamic X2 GP-12 PWM 87.6 CFM against SilverStone FQ121 67.5 CFM, a 23% lead for Fractal Design Dynamic X2 GP-12 PWM. Add static pressure to that, 2.3 mmH2O on the Fractal Design Dynamic X2 GP-12 PWM versus 1.82 mmH2O on the SilverStone FQ121, and the pattern holds. Fractal Design Dynamic X2 GP-12 PWM also leads on max speed, 2000 RPM on the Fractal Design Dynamic X2 GP-12 PWM versus 1800 RPM on the SilverStone FQ121. Colors is not the same on both, Black/White on the Fractal Design Dynamic X2 GP-12 PWM versus Blue blades, white frame on the SilverStone FQ121.
Who each one is for
The Fractal Design Dynamic X2 GP-12 PWM suits silent PC builds and Fractal Design case upgrades, though it is the wrong buy for high static pressure radiator duty and show-window RGB builds. The SilverStone FQ121 is the one to take for CPU heatsink fans and filtered intake with dust screens, though it is not the pick for RGB builds and maximum airflow case builds. Our rating of the Fractal Design Dynamic X2 GP-12 PWM (7/10): one of the quietest 120mm fans around, ideal for anyone building around Fractal's own low-noise philosophy. Our rating of the SilverStone FQ121 (7/10): A quiet, capable static-pressure fan that undercuts the premium brands without giving up much performance.
What Fractal Design Dynamic X2 GP-12 PWM and SilverStone FQ121 have in common
The common ground is wider than the gap: fan size, lighting, fan thickness, pwm control and positioning are identical here.
