Product information

Description

Silent Wings 4 120mm PWM high-speed delivers near-silent operation and high performance in a compact 120mm fan. It combines an advanced 6-pole motor, anti-vibration mountings and aerodynamically optimized blades to provide increased airflow while minimizing noise, making it suitable for demanding cooling tasks in high-end computer systems.

Advantages

The 6-pole motor ensures smooth, efficient rotation and stable high-speed operation. Anti-vibration mountings reduce transfer of vibrations to the case, lowering perceived noise. Optimized fan blades maximize airflow and static pressure for improved cooling performance without a proportional increase in noise levels.

Key specifications

  • Form factor: 120 mm fan
  • Control: PWM (pulse-width modulation)
  • Motor type: 6-pole motor
  • Mounting: anti-vibration mountings
  • Design focus: optimized blades for maximum airflow and static pressure

How to use

Install the fan in a compatible 120 mm mounting location in the computer case or on a radiator, aligning the airflow direction as required. Connect the PWM cable to a motherboard or fan controller PWM header to enable speed regulation. Use the anti-vibration mountings when fastening to reduce mechanical noise transfer. Regularly check for dust buildup and clean as needed to maintain optimal airflow and cooling efficiency.

Recommendations

For best results in high-end systems, pair the fan with a PWM-capable motherboard header and position it to support case airflow or radiator cooling; ensure periodic cleaning to sustain performance and low noise.
