be quiet! Silent Wings Pro 4 120mm PWM Fan

be quiet!’s top 120mm fan: up to 3000 RPM on demand, near-silent at everyday speeds, with a switch to cap the maximum speed.

The Silent Wings Pro 4 is built for radiators and dense heatsinks. Its blades sit very close to the frame with funnel-shaped outlets, so it produces 5.31mm H2O of static pressure and up to 83.9 CFM, yet the six-pole, three-phase motor and fluid dynamic bearing keep vibration and noise low at normal speeds. A switch on the frame selects medium, high or ultra-high maximum speed so the fan can be tuned to the job without software.

Quiet by design

Zero RPM mode lets the fan stop completely under PWM control at idle, and the bearing is rated for 300,000 hours. Three sets of mounting corners are included: radiator corners, anti-vibration corners and standard plastic corners.

Fitting

Connects to any 4-pin PWM header with a 500mm sleeved cable. Punch can fit Silent Wings Pro 4 fans to a cooler or case in a new build and set the fan curve for quiet operation.

Ideal for

• Thick radiators and high-end air coolers
• Quiet workstations that need headroom under load
• Replacing a noisy stock fan
