This article covers be quiet! Silent Wings Pro 4 120mm PWM 3000rpm ケースファン.

Overview

The be quiet! Silent Wings Pro 4 120mm PWM 3000rpm is a premium case fan engineered for users who demand both whisper-quiet operation and exceptional cooling performance. With a maximum speed of 3000rpm and a noise level of just 36.9dBA, this fan strikes an impressive balance between airflow and acoustics. It features a 6-pole fan motor and fluid dynamic bearing for ultra-smooth, low-vibration operation. This model is specifically optimized for use on radiators and heatsinks, thanks to its specialized fan blades and a funnel-shaped air outlet that generates extremely high static pressure. At normal operating speeds, the fan is nearly inaudible, making it an excellent choice for silent PC builds.

Compatibility Guide

The Silent Wings Pro 4 120mm is a standard 120mm fan, compatible with any case, CPU cooler, or radiator that supports 120mm fan mounting. It uses a 4-pin PWM connector, allowing the motherboard to automatically control fan speed based on temperature. A built-in speed switch lets you select the maximum PWM speed among three presets: Medium (1600rpm), High (2500rpm), and Ultra-High (3000rpm). * Ideal for use as a case fan or as a radiator fan for AIO liquid coolers, where high static pressure is critical.

Product Info

Released in 2022, the be quiet! Silent Wings Pro 4 120mm PWM 3000rpm sits firmly in the high-end segment of the case fan market. It is sold as an officially authorized product in Japan and comes with manufacturer warranty. Its market positioning is clear: this is a premium fan for enthusiasts who want the best possible combination of silence and cooling efficiency. It is particularly well-suited for high-airflow builds and water-cooling setups. Fan dimensions: 120mm x 120mm x 25mm Max speed: 3000rpm (switchable to 1600/2500/3000rpm) Noise level: up to 36.9dBA Connector: 4-pin PWM * Rated voltage: 12V, power consumption: 3W

Best Use Cases

High-end gaming PC builders: For systems with powerful CPUs and GPUs, efficient case airflow is essential. The high static pressure design of this fan ensures effective cooling even through dense radiator fins or restricted intake areas. Silent PC enthusiasts: By setting the speed switch to Medium (1600rpm), the fan operates nearly silently. The fluid dynamic bearing and 6-pole motor keep vibration to a minimum, creating a truly quiet environment. * Users seeking radiator fans: The optimized blade shape delivers peak performance on radiators and heatsinks. Even high-density fin stacks benefit from the strong static pressure this fan provides.

Things to Consider

At the maximum 3000rpm setting, the noise level reaches 36.9dBA, which is higher than typical silent fans. If you plan to run it in Ultra-High mode, consider using sound-dampening case panels or a fan controller to fine-tune the speed. This model is only available in the 120mm size. It will not fit 140mm fan mounts, so double-check your case or radiator compatibility before purchasing. The price is higher than standard case fans, but the build quality, performance, and silence justify the premium. If budget is a primary concern, more affordable alternatives may be worth considering.
