Product Description

Manufacture # Cooler Master | Model # MCS-S400-KN5N-S00


The Silencio’s minimalistic design cloaks its complexity. Design elements fine-tuned in form and function result in minimized noise and efficiently maintained system temperatures.



  • Available with seamless tempered glass or a sound-dampened steel side panel, systems can be built for show or for stealth with the Silencio.
  • For an even higher demand for ventilation, the top panel’s Sound Dampening Cover can be removed for unrestricted ventilation. An optional dust filter for the top panel ventilation is included, allowing the top panel and front panel work in conjunction to cool the system.
  • The steel front door features a reversible mounting system, capable of opening in either direction. To prevent vibrations, a softer, thicker material spans the steel structure in conjunction with a hinge system of magnets and rubber stompers.
  • Two Silencio FP 120mm PWM fans are pre-installed with rubber padding to reduce noise, featuring specially designed blades that allow both quiet operation and high air pressure.
