Silent Wings 4 120mm PWM High-Speed — White

2500 RPM max76.7 CFM31.2 dB(A)5-Year Warranty

The be quiet! Silent Wings 4 120mm PWM High-Speed is a white 120 mm 4-pin PWM case fan that reaches 2500 RPM and 76.7 CFM at 31.2 dB(A), aimed at builders who need extra airflow and static pressure for radiators, tower heatsinks and high-performance gaming PCs. Its part number is BL115, and it pairs a fluid-dynamic bearing rated for 300,000 hours with a 6-pole, 3-phase motor and a 5-year be quiet! warranty.

Typically in stock with fast delivery across Cyprus.

Compatibility note: This is a single 120 mm fan (25 mm thick) with a standard 4-pin PWM connector on a 500 mm cable, so it runs from any motherboard fan header or PWM fan hub. Zero RPM (fan-stop) behaviour depends on your motherboard or controller settings. It has no RGB lighting and no hub is included — check that your case or radiator has 120 mm fan mounts.
Best For
✓ Radiators and AIO liquid coolers
✓ High-airflow gaming PCs
✓ Tower heatsinks and mesh fronts
✓ Hot-running or overclocked systems
✓ Filtered front intakes
✓ Replacing noisy stock fans

Key Features

 
Fluid-Dynamic Bearing
The FDB bearing is rated for 300,000 hours at 25 °C, giving very quiet, long-life operation for years of daily use.
 
6-Pole, 3-Phase Motor
A 6-pole motor reduces vibration and motor noise, keeping the fan smooth and quiet across its whole PWM speed range.
 
High-Speed Performance
Up to 2500 RPM, 76.7 CFM and 3.96 mmH2O static pressure for radiators, heatsinks and filtered intakes.
 
Complete Mounting Kit
Screws, push pins, washers and rubber/hard-plastic mountings are included, plus a 500 mm cable with cable sleeve for tidy builds.

Frequently Asked Questions

Does the be quiet! Silent Wings 4 120mm PWM High-Speed work with my motherboard?
Yes. It uses a standard 4-pin PWM connector, so any motherboard fan header or PWM fan hub can control its speed automatically. A 4-pin fan can also be plugged into a 3-pin header, where speed is controlled by voltage instead.
Is the Silent Wings 4 120mm PWM High-Speed suitable for radiators?
Yes. With 3.96 mmH2O static pressure at 2500 RPM, the high-speed version is the better Silent Wings 4 choice for radiators, tower heatsinks and filtered intakes.
What is the difference between the Silent Wings 4 120mm PWM High-Speed and the Silent Wings 4 140mm PWM High-Speed White (BL117)?
The 120 mm high-speed model spins faster (2500 RPM) and builds more pressure (3.96 mmH2O) for 120 mm radiators and heatsinks, while the 140 mm high-speed model moves slightly more air (78.4 CFM) at a lower 1900 RPM and 29.3 dB(A). Choose by the fan mounts in your case or radiator.
What do I need to know before buying the Silent Wings 4 120mm PWM High-Speed?
It is a single 120 mm, 25 mm-thick fan without RGB lighting and without a hub, so you need a free 120 mm mounting position and a fan header or PWM splitter for each fan. It is covered by a 5-year be quiet! warranty.
Singular Expert Insight
Silent Wings 4 sits between the budget Pure Wings 3 and the flagship Silent Wings Pro 4: you get a 300,000-hour fluid-dynamic bearing and a 6-pole motor without paying for the Pro 4 speed switch. This high-speed version is the one to pick for radiators and hot systems; if silence matters more, the standard PWM version is quieter. For lighting, look at be quiet! Light Wings instead, or browse all case fans to compare sizes and packs.

Buyer's Guide

Buy it if
You want a quiet, long-life 120 mm fan with a 300,000 h FDB bearing, 31.2 dB(A) at full speed and a 5-year warranty.
Skip it if
You want the quietest possible fan (the standard Silent Wings 4 PWM is quieter) or you want RGB lighting.
Also consider
be quiet! Silent Wings Pro 4 for more performance with a 3-step speed switch, or be quiet! Light Wings for ARGB lighting.
