Cooler Master announces a pair of additions to the Silencio PC chassis range-- the Silencio S400 and S600, both featuring a minimalist design allowing for minimal noise and maximum thermal efficiency.
According to the company, the two cases refine "long-established strengths of silence optimization and thermal efficiency." To back such claims, Cooler Master says it tested the S400 and S600 using Sorama Cam64, an audio visualisation system allowing one to find and target sources of noise, vibrations and resonance throughout the chassis, leading to construction in materials of varying densities in order to improve on the quality of the "silence."
The chasses feature construction in steel, plastic and "sound dampening material." The sound dampening top cover is removable in order to increase ventilation, while the steel front door features a reversible mounting system capable of opening in two directions. The S400 includes an HDD cage one can shift to the front for more PSU clearance, backwards for additional front radiator space or remove completely in case they are not using HDD storage.
An included pair of Silencio FP 120mm PWM are pre-installed with rubber padding to reduce noise, and an included 4-pin 1-to-3 splitter allows the connection of additional fans. The front I/O panel features an SD card reader and a headset jack with both audio and microphone capabilities, eliminating the need for separate jacks.
The S600 is the larger option, and as such is compatible with full-size ATX motherboards. offers more expansion slots and drive bays, and supports larger graphics cards (up to 398mm). The S400 supports Mini-ITX and Micro-ATX motherboards, but otherwise fits a similar number of fans and radiators to the S600.
The Silencio S400 and S600 should be available soon with a choice of steel or tempered glass side panel.
