Introducing the EK-Pro GPU Zotac RTX 5090 Water Block for High-Density AI and Workstation Systems

EK by LM TEK has unveiled the EK-Pro GPU Zotac RTX 5090, a cutting-edge single-slot water block engineered specifically for demanding AI server deployments and professional workstation environments. Designed exclusively for the ZOTAC Gaming GeForce RTX 5090 Solid series, this full-cover water block delivers advanced active cooling for the GPU core, VRAM, and VRM, ensuring ultra-low operating temperatures and sustained peak performance.

Optimized Cooling for Enterprise-Grade Performance

The EK-Pro GPU Zotac RTX 5090 water block incorporates EK’s renowned Open Split-Flow cooling engine, which provides outstanding thermal efficiency and low hydraulic restriction. This innovative design enables highly effective liquid cooling, even at reduced pump speeds, making it ideal for multi-GPU setups and enterprise-level custom liquid cooling loops.

The jet plate and fin geometry have been meticulously optimized to ensure uniform coolant distribution and minimal flow resistance. This guarantees consistent performance, even in reverse-flow configurations, which is essential for complex server and workstation builds.

For seamless integration in high-density environments, the water block features a 45° angled terminal block with two G1/4" ports. This allows for easy connection with EK-Pro QDC kits and manifolds, streamlining installation and maintenance in compute-intensive applications.

Single-Slot Design for Maximum Compute Density

The EK-Pro GPU Zotac RTX 5090 water block transforms the standard 3.5-slot air-cooled graphics card into a sleek, single-slot solution. This compact form factor is ideal for AI servers and professional workstations where maximizing compute density and maintaining optimal thermal performance are paramount.

Active liquid cooling ensures that even in multi-stack 4U8GPU server rack configurations, the GPU operates at peak efficiency with minimal thermal throttling. The inclusion of quick-disconnect fittings further simplifies maintenance, reducing downtime and supporting continuous operation in mission-critical environments.
