- Vibration reduction and low noise: The case fan TL-C14C features four soft silicone corner pads on all four sides to reduce vibration and friction from rotation, delivering quieter operation while cooling. - Silent size and specs: Model TL-C14C, 140x140x25 mm, speed 1500 RPM ± 10%, noise ≤ 26.4 dBA. Power connector: 4-pin PWM; current: 0.13 A; air pressure: 1.93 mm H2O; air flow: 75.8 CFM. Higher air flow for improved cooling performance. - PWM function: PWM control automatically adjusts fan speed according to motherboard temperature, eliminating manual fixed-speed changes while providing up to 75.8 CFM of airflow as needed. - 1500 RPM and material: Maximum speed 1500 RPM for strong heat dissipation. The fan is made of industrial-strength PBT to ensure durability and reliability. - Use scenarios: Ideal for gaming desktops requiring solid cooling with low noise; suitable for quiet home/office PCs; well suited for compact or custom builds where 140 mm airflow is beneficial.
