Dual Chamber Design
With a 4.5U upper chamber dedicated to GPU deployment and a 2U lower chamber for system components, the IW-RG650PRO maintains clear separation between high-density compute hardware and supporting system zones. This layout enhances airflow management and ensures stable, continuous 24/7 operation under demanding HPC and AI workloads.
PCIe Gen5 Ready
The system comes pre-installed with six next-generation PCIe Gen5 riser cables, enabling immediate deployment of high-end GPU configurations. Additionally, seven low-profile PCIe slots are available for AI expansion, supporting flexible integration of networking, high-speed storage, or future accelerator cards as system requirements evolve.

Robust Airflow with Dedicated Air Ducting
The RG650 PRO employs a precision-engineered thermal architecture featuring independent airflow paths for the GPU and system chambers, eliminating thermal crosstalk between components. Dedicated air ducts direct cooling airflow to high-heat zones, maximizing thermal efficiency and ensuring peak stability during sustained, performance-critical workloads.
Intelligent Cooling & Precision Fan Control
The IW-RG650 PRO features an advanced cooling management system with onboard thermal sensors monitoring both GPU and CPU zones. Dynamic PWM control adjusts fan speeds in real-time based on thermal conditions to optimize cooling efficiency. Supported by three dedicated fan control boards, the chassis incorporates 12 hot-swappable 80x56 mm fans capable of reaching 17,000 RPM. This high-static-pressure fan array delivers responsive, targeted airflow to ensure maximum reliability during continuous, high-load AI operations.
