Novonest PC Case Fans 120mm PWM High Performance Silent Fans PWM 4PIN Connector PC Parts Cooling Fans 3-Pack All Black [NK12BK4-3]

[High-Performance Cooling Fan] A 120mm size frame, the most common general-purpose fan for computer cases or CPU radiators. The square design creates higher airflow without sacrificing ultra-quiet operation, thereby providing efficient ventilation. [Equipped with PWM Function] PWM is a control that suppresses rotation speed and automatically changes the rotation speed according to the amount of heat generated. The PWM fan can be automatically controlled by the CPU temperature to provide optimal cooling performance. It supports any rotation speed from low 900 RPM to high 1800 RPM. It exhibits high vibration damping performance with built-in anti-vibration rubber. It is an item that combines powerful airflow and quietness. [Quiet and Efficient] Made of lightweight material, it can blow air quietly. The four corners of the fan are equipped with shock-absorbing rubber pads, achieving excellent vibration damping and fan stability. It reduces noise and enhances quietness. ▾Equipped with long-life hydraulic bearings, it can rotate continuously for 40,000 hours. [Superior Cooling Performance] The 9 fan blades effectively improve directionality, prevent vibration, and maintain quiet operation. The airflow splitting design allows for efficient heat dissipation, rapidly lowering temperatures by 10-15°C. Airflow reaches 86.34 CFM, ideal for cases and radiators. [Package Contents & Warranty] 3 fans per set, 12 mounting screws, 3 sets of rubber pads x 4. ★Note: Our products come with a 12-month manufacturer's warranty.
