The Prisma AL fans provide intense, even lighting thanks to the six centrally mounted LEDs that shine through the semi-transparent ring and fan blades, illuminating the entire fan surface. Support for ASUS Aura, Gigabyte Fusion, MSI Mystic Light, and ASRock Polychrome allows for precise control and enables harmonious synergy effects with your other components. For even more direct, software-free control, Prisma fans can be complemented with the separately available Adjust R1 RGB controller to adjust colors, brightness, and lighting effects at the push of a button. As with all Fractal Design fans, the focus is on achieving the quietest operation possible. With integrated vibration-dampening corners, smoothly running LLS bearings, and PWM options for precise speed control, the Prisma fans are seen but not heard.
