AI Neural Matrix 4U — 2× NVIDIA RTX PRO 6000 Blackwell Liquid-Cooled AI & Visualization Server Datacenter-Class GPU Density in a 4U Rack Footprint The AI Neural Matrix 4U is a liquid-cooled, high-density multi-GPU server built around the LM TEK (EKWB) 4U8GPU10KW chassis, combining two NVIDIA RTX PRO 6000 Blackwell Workstation Edition GPUs with a 64-core AMD Threadripper PRO 9985WX processor in a single 4U rack unit. The system is engineered for large-model AI training and inference, professional visualization, GPU-accelerated rendering, generative AI, deep learning, and scientific computing. Its defining feature is the chassis's custom liquid-cooling architecture. Two high-performance GPUs operating simultaneously generate a thermal load that conventional air-cooled 4U designs are not built to sustain, typically requiring 6U to 8U or more of chassis space to provide adequate airflow. The LM TEK platform instead applies dedicated liquid cooling blocks to the CPU and to each individual GPU, moving heat out of the chassis through a closed liquid loop rather than through fan-driven air volume. This is what allows two RTX PRO 6000 GPUs to be deployed at full 4U density The result is datacenter-class GPU throughput that can be operated in a standard server room or dedicated IT room, on infrastructure the business owns and controls, rather than requiring a purpose-built data hall or a recurring cloud GPU contract. Liquid Cooling Architecture The RTX PRO 6000 cards are supplied in their standard air-cooled form factor. Each card's stock cooling is replaced with a dedicated full-cover water block with active backplate, and the CPU is fitted with a separate cooling block. All eight cooled components tie into a single closed loop via EKWB cooling architecture. Advantages over conventional air cooling at this GPU density: • Direct liquid heat transfer from the CPU and each GPU, rather than dependence on high-volume chassis airflow • Cooling architecture engineered around the full seven-GPU + CPU thermal load as a single system • Reduced footprint: 4U rack space versus 6U–8U+ typically required for air-cooled configurations at this GPU count • Quick-disconnect fittings on each GPU loop segment allow an individual card to be removed for service or replacement without draining the entire loop • Deploys in standard server-room conditions Liquid cooling manages heat transfer within the chassis; it does not eliminate the total heat output of the system. Adequate room-level HVAC and ventilation are still required for deployment. Component-Level Upgradability Unlike sealed or vendor-locked appliance-style AI servers, this platform is built on standard, individually serviceable components, allowing targeted upgrades as workloads or hardware generations change rather than requiring a full system replacement: Component Current Configuration Upgrade Path Storage 2× 4TB NVMe SSD in 2 of 4 M.2 slots 2 additional M.2 slots available for direct capacity expansion Sys
