Manufacturer description
The be quiet! Silent Wings 4 120mm PWM fan is built for builders who want airflow without the drone. Its 6-pole motor and fluid-dynamic bearing keep vibration low and rotation smooth, while the 1600 RPM PWM ceiling gives your motherboard room to throttle the fan down to near-silence during light loads and ramp it back up under gaming or rendering sessions. The blade geometry pairs a small tip clearance with a funnel-shaped air outlet on the frame, so the Silent Wings 4 pushes air through restrictive surfaces like radiators and dense dust filters rather than just spinning freely in open air…

Frequently Asked Questions
How loud is the Silent Wings 4 at full speed?
be quiet! rates it as virtually inaudible at regular operating speed, and the 1600 RPM ceiling is low by 120mm standards. Exact dBA figures vary by mounting surface; check the product listing for the manufacturer's rating.
Can I use this fan on an AIO radiator?
Yes. The small tip clearance and funnel-shaped air outlets in the frame are designed for high static pressure, which is what radiators and dense dust filters need. Screw mounting is included for radiator installation.
Does it need a 4-pin PWM header?
It is a 4-pin PWM fan, so a 4-pin motherboard or AIO header lets you run a full fan curve. It will still spin on a 3-pin header, but speed control there depends on your board's voltage control.
Is this fan worth it over a cheaper 3-pack of case fans?
As a single fan it is a premium buy, but the fluid-dynamic bearing and 6-pole motor target builders replacing noisy stock fans rather than filling every slot on a budget.
What is included in the box for mounting?
be quiet! includes anti-vibration push pins plus a screwed installation option, so you can choose rubber-decoupled mounting in a case or rigid screw mounting on a radiator or heatsink.
