Product information

Description

The Cooler Master Silencio S400 is a Midi Tower PC case designed for quiet operation without sacrificing thermal performance. It comes in black with options for a tempered glass side panel or a sound-dampened steel side panel, supports Mini-ITX and Micro ATX motherboards, and accommodates multiple drive sizes. Sound-dampening material lines the case, fans are rubber-padded, and a removable top sound dampening cover allows increased ventilation when needed.

Advantages

The Silencio S400 combines noise reduction and airflow flexibility: sound-dampening material minimizes noise from fans, the power supply and steel panels while maintaining effective intake through a ventilated front door with a mesh filter. A reversible sound-dampened steel front door, configurable HDD cage and pre-installed Silencio 120 mm PWM fans with rubber padding increase usability. The I/O panel includes an SD card reader and a single 4-pole headset jack for combined audio and microphone use.

Suitable for

  • Quiet office or home PC builds where low noise is a priority
  • Mid-range systems using Mini-ITX or Micro ATX motherboards
  • Builds requiring flexible storage and radiator placement

Key specifications

  • Form factor: Midi Tower
  • Supported motherboard sizes: Mini-ITX, Micro ATX
  • Drive bays: 4 × 3.5", 4 × 2.5", 1 × 5.25"
  • Pre-installed fans: 2 × 120 mm Silencio FP PWM (rubber-padded)
  • Front I/O: 2 × USB 3.2 Gen 1 Type-A, SD card reader, 1 × 4-pole headset jack
  • Side panel options: Tempered glass or sound-dampened steel
  • Materials: Steel, plastic
  • Dimensions (W×D×H): 210 × 418 × 408 mm
  • Weight: 7.03 kg
  • Colour: Black

How to use

Install the compatible Mini-ITX or Micro ATX motherboard and position storage drives in the HDD cage, which can be moved forward for extra PSU clearance, moved backward for additional front radiator space, or removed entirely if not needed. Use the reversible front door to orient airflow as required. Keep the top sound dampening cover installed for quieter operation, or remove it to increase ventilation for high-demand systems. Connect additional fans using the included 4-pin 1-to-3 splitter if needed.

Usage recommendations

For a balance of silence and cooling, keep the sound-dampened front door and top cover in place during normal operation and remove the top cover only when additional airflow is necessary; regularly clean the front mesh filter to maintain efficient intake.
