EK by LM TEK is proud to announce the EK-Pro GPU WB H200 NVL, a high-performance full-cover GPU water block designed for the NVIDIA H200 NVL. Engineered for high-density AI server deployments and data center environments, the block features a single-slot form factor optimized for maximum compute density and system compatibility. By covering the entire PCB, the EK-Pro water block directly cools the GPU, HBM memory, and VRM ensuring optimal thermal performance, stability, and sustained performance under demanding workloads. The low-profile, rack-style terminal design reduces overall assembly height, improving chassis compatibility across standard Full Height Full Width (FHFW) server platforms. This enables seamless integration as a drop-in replacement for both active and passive dual-slot air coolers.

Dual-Pass Cooling Engine for Maximum Thermal Efficiency
At the core of the EK-Pro GPU WB H200 NVL is a dual-pass cooling engine, engineered to maintain high flow rate. The coolant flows sequentially through two optimized microfin stacks, cooling each half of the GPU die and HBM memory to ensure uniform heat dissipation. This design maintains consistent flow distribution and thermal performance, minimizing losses even in reversed flow scenarios, while delivering efficient cooling across the entire GPU surface.
