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. 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. The high-brightness LED atomizing argb fan blade can effectively reflect the light, making the ARGB lighting effect softer, and it matches the cooler and case more perfectly. Up to 17 modes of light effects with ARGB support. Model: TL-C12C-S X3, Size: 120*120*25mm, Speed: 1550RPM±10%, Noise 25.6dBA Connector: 4pin pwm, Current: 0.20A, Air Pressure: 1.53mm H2O, Air Flow: 66.17CFM. 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.
