1. Unique Shape The pure white CPU fan features slim round ARGB lines on the front and back, enhancing its value. Soft silicone feet reduce noise and make the fan more cost-effective. 2. PWM Function PWM control automatically adjusts fan speed according to motherboard temperature, eliminating manual fixed-speed tuning. Provides 47.6 CFM airflow for effective cooling. 3. ARGB Lighting Effect Double-sided ARGB thin light strip uses UPT process technology; the light bar is 0.6 mm wide for seamless, delicate chassis lighting. Recommendation: number of fans in series should be less than 6. 4. Silent Fan Size Model: TL-S12R X3; Size: 120 x 120 x 25 mm; Speed: 1500 RPM ±10%; Noise: ≤ 23.2 dBA; Connector: 4-pin PWM; Current: 0.15 A; Air Pressure: 1.31 mm H2O; Air Flow: 47.6 CFM. Higher airflow delivers improved cooling performance. Use scenarios - Quiet desktop builds: integrates into a standard PC where low noise and automatic cooling are priorities. - Gaming or visually enhanced rigs: ARGB lighting adds atmosphere while PWM maintains stable temperatures. - Multi-fan setups: suitable for cases supporting ARGB and series connections, with the recommended limit of fewer than 6 fans in series.
