Who each one is for

The Cooler Master SickleFlow 120 is the one to take for budget builds without a case window and filtered intake positions on a tight budget, though it is not the pick for showcase builds wanting lighting and premium quiet-first builds. The SilverStone AP121 suits SilverStone case builds wanting brand-matched fans and balanced airflow and static pressure needs, though it is the wrong buy for builds chasing best-in-class performance and RGB or showcase builds. Our rating of the Cooler Master SickleFlow 120 (6/10): A dependable budget fan that performs identically to its pricier RGB sibling for less money. Our rating of the SilverStone AP121 (6/10): A competent, unremarkable fan best chosen for brand consistency in a SilverStone build rather than outright performance.
