[PWM Function] CPU fan with PWM function, the fan can automatically adjust the speed according to the temperature of the motherboard, no need to manually adjust the fixed speed, 47.6CFM airflow can provide the desired cooling effect. [ARGB Lighting Effect] Double-sided ARGB thin light strip adopts UPT process technology, the width of the light bar is 0.6mm, which presents seamless and delicate lighting effects for the chassis. It is recommended that the number of fans in series is less than 6. [Detailed Optimisation] The desktop fan is paired with a 55CM long cable, 4PIN PWM connector is the fan's power supply connector, and 5V 3PIN ARGB is the light connector, supporting PWM/ARGB serial control of the fan, please connect the fan's connector to the corresponding connector on the motherboard. [Silent Fan Size] Model: TL-S12RW X3, Size: 120x120x25mm, Speed: 1500RPM10%, Noise less than equal 23.2dBA Connector: 4pin pwm, Current: 0.15A, Air Pressure: 1.31mm H2O, Air Flow: 47.6 CFM, Higher air flow for improved cooling performance. [Perfect Match] The PC fan can be used not only as a case fan, but is also suitable for use with a cpu cooler to create a cooling effect together, which can take away the dry heat from the case and the high temperature generated by the CPU in operation, allowing for maximum cooling; Ideal for cases, heatsink cooler and CPU air coolers. Adding halo argb light ring while maintaining fan blade area for less airflow performance sacrifice.
