Our Prisma AL Series ARGB fans allow your system to truly shine. Six hub-mounted addressable RGB LEDs work in harmony with a white semi-opaque outer ring and fan blades to produce a beautifully uniform glow across the fan’s entire surface. . Prisma AL-12/14 allows precision software control, enabling Prisma to synergize perfectly with your components. If you prefer physical control, just pair Prisma with the newly released Adjust R1 controller to set colors, brightness, and motion effects with the push of a button. As with any Fractal Design fan, silence remains a central focus with integrated vibration damping corners, silent LLS bearings, and PWM options for complete control over the speed of your fans, ensuring Prisma is seen, not heard. . PWM control with a wide speed range ideal for CPU heatsinks and radiators. Specially designed white semi-opaque fan blades and outer ring produce an exceptionally uniform glow. Aerodynamic stator struts with embedded wiring reduce noise and turbulence. Trip Wire technology introduces a micro-turbulent layer for enhanced blade efficiency. Integrated vibration-damping corners made from high-quality synthetic rubber. LLS (Long Life Sleeve) bearings provide silent operation with a long lifespan. 3 Years warranty is active from the point of purchase.
