Silencio Technology

The development of the Silencio chassis was driven by the Sorama Cam64 Acoustic Camera, which 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 optimised the Silencio for thermal efficiency and silence, from the type of material used to its placement.

Sound Dampening Material

The Silencio utilises a combination of sound dampening materials, located on the front door and both side panels. This thick soft foam precisely counters prominent frequencies, helping to reduce any air-born noise.

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 work in conjunction to cool the system.

Ventilation Front

The front panel features a re-curved 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 can be shifted forward to make room for a longer PSU, or moved backwards for additional radiator space. It can even be completely removed if HDD storage is not required.
