Who each one is for
Buy the Cooler Master MasterFan MF120 Prism for Cooler Master RGB ecosystem builds and show-window mirror-finish aesthetics, though it is not the pick for max-static-pressure radiator duty and silent builds. The Corsair LL120 RGB is the one to take for iCUE-based RGB builds and case intake/exhaust with visible ring lighting, though it is the wrong buy for high-restriction radiator duty and silent 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 Corsair LL120 RGB (6/10): still a good-looking fan for iCUE builds chasing the dual light-ring look, but outperformed by Corsair's own newer lineup.
Where the two are identical
The common ground is wider than the gap: fan size, lighting, pwm control, positioning and colors are identical here.
