Efficient Cooling : Features a single-tower design with four pure copper heat pipes and an optimized 120mm PWM fan (TL-C12C) for excellent performance, keeping CPUs cool under heavy workloads. Quiet Operation : The TL-C12C PWM fan operates at 1550 RPM (±10%) with a maximum airflow of 66.17 CFM and a low noise level of ≤25.6 dB(A), balancing cooling efficiency with quietness.
