be quiet! Silent Wings Pro 4 140mm PWM White
140 mm · up to 2400 RPM97.4 CFM3.64 mmH2OFDB · 5-year warranty
The be quiet! Silent Wings Pro 4 140mm PWM (part number BL119) is a premium 140 mm white case and radiator fan that reaches up to 2400 RPM, built for enthusiasts who want high static pressure without giving up acoustic refinement. A three-step speed switch on the frame sets the maximum PWM speed, while the fluid dynamic bearing and 6-pole 3-phase motor deliver smooth, quiet operation with a rated lifespan of 300,000 hours.
Typically in stock with fast delivery across Cyprus.
Compatibility note: This is a single fan with a 4-pin PWM connector — it needs a free 4-pin fan header or hub on your motherboard. It draws up to 0.50 A (6.0 W), so check the header rating before splitting several fans onto one header. It has no RGB lighting. The 140 mm frame uses standard 140 mm mounting holes; confirm your case or radiator supports 140 mm fans.
Best For
✓ Radiator push or pull setups
✓ High-pressure front intake behind mesh or filters
✓ Quiet high-end gaming builds
✓ Workstations that need strong cooling headroom
✓ Premium white or black themed builds
✓ Replacing stock case fans
Key Features
3-Step Speed Switch
A switch on the frame limits the maximum PWM speed to medium, high or ultra-high (up to 2400 RPM), so you choose between silence and maximum cooling without changing BIOS curves.
Exchangeable Corners
Radiator corners come pre-installed, with rubber anti-vibration and hard plastic corners included, so the fan can be tuned for radiators, case panels or low-vibration mounting.
High-Pressure Design
A funnel-shaped outlet and small blade tip clearance push 97.4 CFM at 3.64 mmH2O — strong enough for dense radiators and restrictive front panels.
FDB Bearing + 3-Phase Motor
The fluid dynamic bearing and 6-pole 3-phase motor keep vibration and motor noise low, with a rated lifespan of 300,000 hours at 25 °C and a 5-year warranty.

Buyer's Guide
Buy it if
You run a radiator or restrictive front panel and want up to 2400 RPM with a hardware speed switch and a 5-year warranty.
Skip it if
You want RGB lighting or only need low-speed exhaust airflow — a cheaper 3-year-warranty fan is enough.
Also consider
