CORSAIR RS140 ARGB PWM 140mm Fan - Simplified Control - Daisy-Chain 4-Pin PWM and +5V ARGB Connections - Concentrated AirGuide Cooling - Magnetic Dome Bearing

The be quiet! Silent Wings Pro 4 140mm PWM White is a flagship non-illuminated case fan engineered for unparalleled performance and silence in high-end applications, featuring newly optimized fan blades with minimal tip clearance and a funnel-shaped frame outlet that generates exceptional static pressure for superior cooling on radiators, heatsinks, or restrictive case meshes. A convenient speed switch enables selection among three PWM modes—medium (up to 1100 RPM), high (up to 1900 RPM), and ultra-high (up to 2400 RPM)—allowing seamless adaptation from whisper-quiet operation to maximum thermal throughput in demanding scenarios.



Advanced acoustics are driven by a 6-pole, 3-phase motor and fluid-dynamic bearing that minimize vibrations, power consumption, and noise, achieving a maximum of just 36.8 dB(A) even at full speed while remaining virtually inaudible in medium mode. Interchangeable mounting corners provide versatile installation options: pre-installed anti-vibration rubberized corners for chassis use, push-pin variants for reduced resonance, and rigid plastic corners optimized for radiator mounting.

The pristine all-white design, including frame, blades, and high-grade sticker, integrates seamlessly into light-themed builds, complemented by a finely sleeved, detachable PWM cable for enhanced aesthetics and ease of routing. With a lifespan rated up to 300,000 hours and broad compatibility via standard 4-pin PWM control, the Silent Wings Pro 4 140mm PWM White delivers elite airflow, extraordinary pressure optimization, and signature be quiet! refinement, making it the premier choice for enthusiasts demanding uncompromising silence and efficiency in showcase white PC systems.
