Patented Design The color and brightness uniformity of the Patented LED ring is visible from all directions and adds style to the chassis. Smart Fan Controller A self-contained fan controller can switch between 5 LED modes including solid colors of red, blue, white, green or disable and cycle through 256 colors. Play/Pause functions allow users to cycle colors (color remains unchanged until click Play/Pause button again) with speed control options reduce noise even more all from your fingertips. Concentrated Compression Blade Custom designed for high static pressure requirements of demanding applications such as radiators, the concentrated compression blade is engineered to focus the weaker, inner circle of air outward, allowing the outer section to pressurize the air. Hydraulic Bearing with Low-Noise Design The hydraulic bearing self-lubricates with a high quality, friction-reducing substance which lowers operating noise and improves efficiency. The seal cap prevents leakage of the lubricant, and improves the lifespan of the unit. By clicking the SPEED button on fan controller, the noise level can be reduced to 29%. Wind Blocker Frame To achieve maximum static pressure in all applications, the wind blocker frame is designed to work with the Concentrated Compression Blade`s (CCB) pressure mechanism by directing airflow towards the middle section of the blade, thereby creating a compression effect and blocking any pressure from escaping. This reduces the blade`s noise and vibration, creating a perfect balance between power and sound. Anti-Vibration Mounting System In-mold injection anti-vibration rubber pads provide hassle-free usage for 80% protection coverage, including all four corners.
