The Silencio Series is Cooler Master’s best solution for sound absorption with system builds of all levels. Sound silencing foam padding will help reduce system noises produced by hard drives, numerous cooling fans, and other devices. Combine this with a solid-steel frame, vibration inhibiting rubber feet, two Cooler Master quiet-spinning fans, and the Silencio 450 should nearly become completely silent. Those who value a quiet computing space should appreciate the Silencio Series. The Silencio 450 also sports more than just sound absorption foam, such as the USB 3.0 connection and the SD card reader. It also brings removable HDD cages, dust filters, and a switchable door hinge to the party as well. However, it will need to step up and pass our testing today … will the Silencio silence its critics or hear them loud and clear.
