SilverStone FQ121 (120mm/49.0 CFM/2.36 mmH2O Static Pressure/1500 RPM Max/25.0 dBA/Fluid Dynamic Bearing/No RGB/PWM) Review
The FQ121 is SilverStone's Air Penetrator design tuned for quiet static pressure, it comes up for people comparing SilverStone's own fan lines against Noctua and Arctic on a heatsink.
It's a sensible, quiet static-pressure fan for a heatsink or filtered intake, not a fan you buy for looks.
Comparison to Alternatives
Against the Arctic P12 PWM PST in our catalog, the FQ121 offers slightly higher static pressure at a similar noise level, making it a close competitor for heatsink and filtered-intake duty. Compared with the Noctua NF-F12 PWM, the FQ121 costs less but runs a couple dB louder at the same static pressure.
