Maximize Airflow, Optimize Performance

The metal mesh front panel features an impressive 51% ventilation rate, allowing unrestricted air intake for superior cooling efficiency. This airflow-focused design ensures stable temperatures even under sustained high-performance gaming or productivity workloads.

Pre-Installed High-Performance PWM Fans

The AIR 903 MAX comes equipped with four HP140 PWM fans, including three 140mm ARGB PWM fans and one standard 140mm PWM fan. These fans deliver an ideal balance between quiet operation and powerful airflow, ensuring effective cooling straight out of the box.

Limitless Cooling & Customization Potential

Designed for advanced cooling setups, the chassis supports 360mm AIO liquid coolers at both the front and top, CPU air coolers up to 180mm tall, and up to nine fans in total. This flexibility allows builders to customize airflow and cooling configurations to suit their exact needs.

Built for Massive GPUs & Future Upgrades

With generous internal spacing, the AIR 903 MAX accommodates graphics cards up to 400mm in length and 190mm in width, making it fully compatible with modern flagship GPUs such as the NVIDIA® GeForce RTX® 40 series. Support for E-ATX and SSI-EEB motherboards ensures seamless installation for large-scale builds.

Advanced Dust Protection & Easy Maintenance

Strategically placed dust filters combined with a quick-release design provide comprehensive dust protection while allowing effortless cleaning. This keeps components cleaner and airflow channels unobstructed over long-term use.
