be quiet! · Silent PWM Case Fan
Silent Wings 4 140mm PWM — White
1100 RPM max51.3 CFM13.6 dB(A)5-Year Warranty
The be quiet! Silent Wings 4 140mm PWM is a white 140 mm 4-pin PWM case fan that reaches 1100 RPM and 51.3 CFM at 13.6 dB(A), aimed at quiet gaming PCs, workstations and home-office builds where low noise matters most. Its part number is BL116, 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 140 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 140 mm fan mounts.
Best For
✓ Silent gaming PCs
✓ Workstations and home-office PCs
✓ Front intake or rear exhaust
✓ Low-noise media PCs
✓ Replacing noisy stock fans
✓ Clean builds without RGB
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.
Whisper-Quiet Operation
Only 13.6 dB(A) at full speed while still moving 51.3 CFM — ideal when silence is the priority.
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
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. If you need more pressure for a radiator, step up to the high-speed version. For lighting, look at be quiet! Light Wings instead, or browse all case fans to compare sizes and packs.
