SILENCIO S400

Cooler Master's Silencio S400 is a masterpiece crafted to deliver the best in design, quietness and cooling performance. The minimalistic look makes a unique statement wherever you place it. Silencio Technology integrates sound dampening material to effectively reduce vibration and counter prominent frequencies, so your system will run extremely quiet. In addition to two pre-installed Silencio FP 120mm PWM fans, it offers support for radiators and more fans to keep your powerful PC cool even at full load.

SILENCIO DESIGN

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.

SILENCIO TECHNOLOGY

Behind the outer panels are pieces of meticulously placed sound dampening material. The development of the Silencio was driven by Sorama's Cam64—this allowed for the entire sound spectrum to be visually analyzed by source, resonance pattern, and frequency.

With the identification of peaks within certain frequency ranges, fine-tuning the Silencio for the dispersion of resonance was made possible, reducing the prominence of noise generated by system components. Every detail in design optimized the Silencio for thermal efficiency and silence, from the type of material used to its placement.

SOUND DAMPENING MATERIAL

The Silencio utilizes a combination of sound dampening materials, from thick soft foam to heavy mass-loaded vinyl, to precisely counter prominent frequencies.

VENTILATION

TOP

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 to work in conjunction to cool the system.

VENTILATION

FRONT

The front panel features a recurved vent, directing air in through the front bezel. The curve points downward, taking air in from the bottom, and straightens out to direct air in from either side of the steel front door.

REVERSIBLE STEEL DOOR

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.

SILENCIO FANS

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.

VERSATILE HDD CAGE

The HDD cage is (re)movable. The cage can be shifted forward to make room for a longer PSU, backwards for additional radiator space, or completely removed if HDD storage is not needed.
