(High Performance Cooling Fan) Automatic speed control of the motherboard through the 4PIN PWM fan cable interface, which can determine the speed according to the temperature of the motherboard, with a maximum speed of 1550RPM. Configured with up to 55cm of cable for PWM series control of fans, ideal for cases and CPU coolers. (Quality Bearings)The carefully developed quality S-FDB bearings solve the problem of pc cooling fan blade shaking in lifting mode, keeping fan noise to a minimum while providing maximum cooling performance when needed and extending the life of the fan. (Vibration reduction and low noise) The case fan is equipped with four soft material silicone corner pads on all four sides, which can reduce the vibration and friction caused by the rotation of the fan, perfectly reducing noise and allowing low noise operation, so that cooling can be carried out in low noise. (Silent Fan Size) Model: TL-C12C X3, Size: 120*120*25mm, Speed: 1550RPM±10%, Noise 25.6dBA Connec
