SilverStone FQ121 Review

SilverStone FQ121 is a 120 mm, 25 mm thick PWM case fan with a fluid dynamic bearing, 1000 to 1800 RPM speed range and blue blades in a white frame, with no RGB.

The FQ121 is a 120 mm case fan rated at 1.82 mmH2O of static pressure. It has a fluid dynamic bearing, PWM control and a speed range of 1000 to 1800 RPM, weighs 143 g and has blue blades in a white frame. There is no RGB lighting. The blue and white look limits how well it matches black builds.

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.
