Verdict
Corsair ML120 PRO RGB
8 / 10 Expert Rating
A proven radiator fan for RGB loops that need real static pressure, if you're willing to tune the PWM curve down from its noisy top end.
SilverStone FQ121
7 / 10 Expert Rating
A quiet, capable static-pressure fan that undercuts the premium brands without giving up much performance.
