Silence meets Airflow – Cooler Master unveils its Silencio 600

Cooler Master aims to deliver silence and high airflow with its new Silencio 600 PC case

OC3D is at Cooler Master HQ, and what they showed us should put an end to the notion that quiet PC cases are hotboxes. Cooler Master has unveiled its new Silencio 600, which aims to deliver strong front-panel airflow while maintaining low noise levels. Low noise levels aren’t coming at the cost of airflow.

At the front of this PC case are two large 180mm “Mighty40” fans. These fans are 40mm thick and deliver high levels of airflow at low RPMs. This enables strong airflow without excessive fan noise.

At the front of the Silencio is a formed fabric front panel designed with airflow gaps. Despite these gaps, it is hard for sound to exit the case this way, as their shape reflects sound back into the case. Furthermore, the panel is made of a sound-absorbing material, further reducing noise levels.

“Sound Maze Technology”

The Silencio 600 uses “Sound Maze Technology” to enable airflow while blocking and dispersing sound. This is how Cooler Master achieves strong case airflow without excessive noise. Add on low-noise fans, and we have a case that’s perfect for low-noise environments.

With modern PCs using higher-power/hotter hardware, airflow is no longer something that can be ignored by PC builders. With their new Silencio, Cooler Master aims to deliver silence and strong airflow, traits that are typically seen as opposites. If you want even stronger airflow, Cooler Master has also unveiled its new HAF II 500 PC case.

Cooler Master was unable to confirm the pricing and exact release date for its Silencio 600. The case is likely to launch around October, though this release timeframe is not guaranteed.
