Pros & Cons

Pros

✓ Blade design and funnel-shaped outlets target radiators and dense heatsink fins
✓ Fluid-dynamic bearing plus 6-pole motor keeps vibration down at full PWM speed
✓ 5-year manufacturer warranty, well beyond typical case-fan coverage
✓ Ships with both anti-vibration push pins and screws for either mounting style

Cons

✗ White colorway limits it to light-themed builds
✗ No RGB or ARGB lighting on the BL115
✗ High-speed variant trades some quiet for static pressure vs. standard Silent Wings 4
✗ 120mm only, so 140mm radiator and case mounts need a different SKU

Manufacturer description

The be quiet! Silent Wings 4 120mm PWM high-speed fan in white is built for the jobs that punish ordinary case fans: pushing air through dense radiator fins and tightly packed heatsink stacks. Its optimized blade geometry runs with a small tip clearance inside a frame with funnel-shaped air outlets, a combination that generates the high static pressure restrictive mounting points demand. Behind the hub, a 6-pole motor paired with a fluid-dynamic bearing cuts vibration at the source, so the fan stays composed even when PWM control pushes it to maximum speed. You get anti-vibration mounting…
