Which should you buy, Cooler Master MasterFan MF120 Prism or SilverStone FN121?
The Cooler Master MasterFan MF120 Prism suits Cooler Master RGB ecosystem builds and show-window mirror-finish aesthetics, though it is not built for max-static-pressure radiator duty and silent builds. Buy the SilverStone FN121 for budget case airflow and quiet everyday builds, though it is not the pick for radiator or heatsink duty and RGB builds. Our rating of the Cooler Master MasterFan MF120 Prism (6/10): A reasonable mid-tier RGB fan, worth it mainly for the mirror-finish look rather than outright performance. Our rating of the SilverStone FN121 (6/10): an unremarkable but reliably quiet budget fan for general case airflow.
