Whisper-Quiet Performance
The Silent Wings Pro 4 achieves its near-silent operation through a sophisticated fluid dynamic bearing that reduces friction and vibration. At maximum speed, the fan produces just 36.9 dB of noise – quieter than a normal conversation. The optimized blade design and specially engineered corners minimize turbulence, creating a smooth, quiet airflow that won’t disturb your work or gaming sessions.
Advanced Cooling Technology
This fan isn’t just quiet – it’s also incredibly powerful. With a maximum airflow of 142.5 m³/h and air pressure of 5.31 mmH2O, it can handle even the most demanding cooling scenarios. The 120mm size fits standard case mounting points, while the 25mm thickness provides optimal clearance for most builds. Whether you’re cooling a CPU heatsink, GPU, or entire case, this fan delivers consistent, reliable performance.
Precision Control with PWM
The 4-pin PWM connector allows your motherboard to precisely control fan speed based on temperature, ensuring you get cooling when you need it without wasting power when you don’t. The built-in speed switch offers three selectable modes, letting you balance between maximum cooling and minimum noise depending on your needs. This intelligent control system helps extend the fan’s impressive 300,000-hour MTBF rating.
