be quiet! Fan 120mm - SILENT WINGS 4 120mm PWM high-speed

be quiet! Silent Wings 4 120mm PWM high-speed is a 120 mm fan that is oriented more towards performance than full silence, but it still maintains the brand's typical low noise and smooth operation. The size of 120 x 120 x 25 mm makes it a standard choice for most cases, radiators, and air coolers. The range of 400 to 2500 RPM gives you freedom – from nearly silent idle to serious airflow when needed. The construction with a dynamic fluid bearing and 6-pole motor is aimed at minimal vibrations and long life.

What you get
With this fan, you can set up your system however you like – low RPMs for quiet everyday use and a sharp increase to 2500 RPM when the CPU or GPU gets hot. PWM control via a 4-pin connector allows the motherboard to dynamically control the RPMs based on temperature, without you having to deal with manual adjustments. The specially optimized blades for radiators and heat sinks help with dense fins – exactly where you need high static pressure, and the small tip clearance and funnel-shaped frame improve airflow through confined spaces. Thanks to the fluid bearing and power consumption of only 2.4 W at 12 V / 0.20 A, you get an efficient, cool, and reliable fan for 24/7 operation.

• Standard size 120 x 120 x 25 mm, which fits most PC cases, radiators, and air coolers.
• Wide RPM range of 400 – 2500 RPM, allowing a balance between silence at idle and strong airflow under load.
• 4-pin PWM connector, so that the motherboard can precisely control the speed according to the system temperature.
• 6-pole motor and fluid-dynamic bearing for less vibration, smoother operation, and reduced wear noise over time.
• Special frame with funnel-shaped openings and small tip clearance for extremely high air pressure – ideal for radiators and dense heat sinks.
• Anti-vibration mounting with push pins and an option for screw mounting, for quieter operation and less resonance with the chassis.
• Long life with MTBF up to 300,000 hours, suitable for long-term builds and 24/7 loaded systems.

Who it is suitable for
Silent Wings 4 120mm PWM high-speed is a good choice if you are after serious cooling for a CPU, GPU, or dense radiator, but do not want a cheap “noisy” fan. It is suitable for both gaming and high-performance machines, as well as for more compact cases where high static pressure is critical. If you are looking for a fan that only runs at low RPMs for an ultra-silent build, this high-speed model might be a bit “overkill” for you.

The combination of a high maximum of 2500 RPM, optimization for radiators, and an extremely long life of up to 300,000 hours makes this fan a very meaningful upgrade when you want reliable cooling without unnecessary compromises.
