1. 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 white fan, reducing noise and allowing low noise operation, so that cooling can be carried out in low noise. 2. Silent Fan Size Model: TLC14C, Size: 140*140*25mm, Speed: 1500RPM±10%, Noise ≤ 26.4dBA; Power Connector: 4pin PWM; Current: 0.13A, Air Pressure: 1.93mm H2O, Air Flow: 75.8CFM, Higher air flow for improved cooling performance. 3. PWM Function CPU fan is equipped with PWM function, the cooler fan can automatically adjust the speed according to the temperature of the motherboard, no need to manually adjust the fixed speed, and the airflow of 75.8CFM can provide the required cooling effect. 4. 1500RPM CPU fan speed up to 1500RPM, speed can achieve heat dissipation, the PC fan material is made of indusialsength PBT, in the heat dissipation at the same time, the quality of the cpu cooling fan is also .
