?? POWERFUL FAN: ?? Our fan comes equipped with an automatic speed control system that connects to the motherboard via a 4-pin PWM fan cable interface. This intelligent setup allows the fan to adjust its speed according to the motherboard's temperature signals, with a maximum speed of 1550 RPM. The 55cm cable is ideal for PWM series fans, making it a perfect fit for cases and CPU coolers. ?? HIGH-QUALITY BEARINGS: ??? Engineered with precision, the S-FDB bearings address the issue of fan blade oscillation during lift-off, minimizing fan noise and maximizing cooling efficiency as needed. This design not only extends the fan's lifespan but also enhances its overall performance. ?? SUPERB LED LIGHTING: ?? The fan blade is infused with dazzling ARGB LEDs, creating a softly diffused lighting effect that beautifully complements your cooler and case aesthetics. With 17 lighting effect modes and synchronized color management via the motherboard port, you can tailor the lighting to suit your preference. ?? QUIET OPERATION: ?? Model: TL-C12CW-S. Dimensions: 120 x 120 x 25 mm. Speed: 1550RPM±10%. Noise level ? 25.6 dBA. Connection: 4-pin PWM. Current: 0.20A. Air pressure: 1.52 mm H2O. Airflow: 66.17CFM. This fan provides enhanced airflow for improved cooling performance while maintaining a quiet operational profile. ??? VERSATILE USE: ??? This PC fan serves multiple purposes. It's suitable for use as both a case fan and in tandem with a CPU cooler to achieve a synergistic cooling effect. This dynamic combination effectively dissipates excess heat from the case and manages the high temperatures generated by the CPU during operation, ensuring optimal cooling. Ideal for cases, coolers, and CPU coolers.
