Switch LED Modes with ARGB Controller
The ARGB controller allows users to switch LED modes, LED colors, and LED Speeds when using a motherboard without a 5V addressable RGB header. Users can switch between flow, ripple, pulse, blink, wave, full light, RGB spectrum, and off modes with various colors and LED speeds options.
The maximum signal output for one controller is 90 addressable LEDs.

PWM Controlled Fan with 9 Fan Blade Design
PWM-controlled fan with a unique 9 blade design is engineered to generate higher airflow while keeping quiet. The Ring Trio fan White ensures more efficient cooling performance under intense operation.

Hydraulic Bearing with Low-Noise Design
The hydraulic bearing design can self-lubricate with a high-quality, friction-reducing substance, lowering operation noise while improving thermal efficiency. The seal cap prevents lubricant leakage and extends the lifespan of the unit.

Anti-Vibration Mounting System
The In-mold injection anti-vibration rubber pads dampen the fan’s vibration, allowing the fan to spin at higher levels without compromising noise levels. The fan is designed with 80% coverage for all corners, maintaining low noise levels when in operation.
