Thermaltake Pure Duo 14 ARGB Sync Radiator Fan 2 Pack Black

PWM controlled fan with an unique 9 blade design is engineered to generate higher airflow whilst keeping quiet. The hydraulic bearing self-lubricates with a high-quality, friction-reducing substance, which lowers operation noise while improving thermal efficiency The seal cap prevents lubricant leakage and extends the lifespan of the unit The In-mold injection anti-vibration rubber pads dampen the vibration of the fan allowing the fan to spin at higher levels without compromising noise levels. 7 preset lighting modes: wave, full light, rgb spectrum, flow, ripple, pulse and blink modes
