Push & Pull Airflow

Efficient cooling and easily accessible dust filters

Keep your system cool and efficient with an optimized push & pull airflow system. The Onyx Vision chassis ensures that fresh air is constantly drawn in, while warm air is effectively dissipated. This design helps to keep temperatures stable even during intense gaming sessions or heavy workloads, reducing the risk of thermal throttling and ensuring your components maintain their optimal performance.
For easy maintenance, the case has a pull-out dust filter underneath the power supply unit, which can be pulled out like a drawer for quick cleaning and convenient access. An additional magnetic dust filter is located behind the side intake fans and helps to keep dust out of the system without affecting the airflow.
