Everything you need to know about this product
The case uses sound dampening materials like soft foam and mass-loaded vinyl, along with Sorama’s Cam64 acoustic analysis to target frequencies and resonance. Vibration-reducing rubber padding on fans and door stompers further lowers structural noise.
Users can select either a seamless tempered glass side panel to show off internal system components, or a sound-dampened steel side panel optimized for maximum noise absorption.
Yes, the case comes with pre-installed Silencio FP 120mm PWM fans that utilize rubber mounting pads and optimized blade profiles to combine high static pressure with silent operation.
Yes, the solid steel front door features a reversible mounting system that allows it to be installed to swing open from either the left or the right side.
Yes, the top panel features a removable sound-dampening cover. It can be swapped out for an included optional dust filter if you want to optimize for extra exhaust ventilation.
The front bezel features curved ventilation channels that draw cool air from the lower portion and both sides of the reversible steel front door to maintain efficient intake levels.
Yes, the modular drive cage can slide backward to clear space for front-mounted liquid-cooling radiators, move forward for longer power supplies, or be fully removed.
The case panels integrate a high-performance layered combination of sound-absorbing soft foam and dense, mass-loaded vinyl to neutralize internal sound waves.
Sorama's Cam64 technology was used to analyze sound spectra, frequencies, and resonance. This acoustic mapping allowed CoolerMaster to fine-tune and position dampening materials where they are most effective.
No, the reversible steel front door is equipped with magnets and soft rubber stompers, along with a thick lining material to eliminate door vibration and cushion closure.
