LM TEK EK-Pro Waterblock Kit for RTX Pro 6000 GPU

Maximise the computational density and thermal efficiency of your enterprise AI infrastructure with the LM TEK EK-Pro Waterblock Kit, a high-performance liquid cooling solution explicitly engineered for NVIDIA RTX PRO 6000 Blackwell Server Edition and MAX-Q Workstation Edition GPUs. Designed to replace bulky air coolers, this premium full cover water block features a true single-slot form factor measuring 306 x 127 x 22 mm, allowing administrators to confidently deploy high density multi-GPU configurations, such as eight accelerators within a standard 4U server rack. It boasts a precision CNC-machined nickel-plated electrolytic copper base and a robust laser cut stainless steel top plate to actively channel coolant over the critical GPU core, VRAM, and VRM components. At its heart, the advanced Open Split-Flow cooling engine guarantees incredibly low hydraulic flow restriction, delivering exceptional heat dissipation even when paired with lower speed pumps in complex, multi-card loops. To further improve system stability and structural rigidity during transport, the kit includes a custom single-slot I/O bracket and a CNC-machined aluminium hybrid backplate that provides essential cooling for backside memory areas. Complete with a rear POM-crafted terminal block featuring standard dual G1/4-inch ports for seamless integration with quick-disconnect fittings and server manifolds, this enterprise-grade EK-Pro water block provides data centres and professional workstations with the mission-critical cooling required for sustained 24-hour operations.

EK-Pro GPU WB RTX PRO 6000 Blackwell Nickel + Inox

The EK-Pro GPU WB RTX PRO 6000 Blackwell Nickel + Inox is a water block for the NVIDIA RTX™ PRO 6000 Blackwell Server Edition. It occupies a single PCIe slot width and is designed for compact workstation and server chassis where adjacent slot clearance is a constraint.

The block efficiently cools the GPU die, VRAM, and VRM with low hydraulic flow restriction, maintaining compatibility with weaker water pump setups. Construction uses a nickel-plated copper base and stainless-steel top with a POM Acetal terminal block carrying two G1/4″ ports.

The retention backplate adds PCB rigidity and provides passive cooling to the VRM area. EPDM O-ring sealing is used throughout.

Key Engineering - Three Design Decisions Worth Calling Out

Single-Slot Server Edition Profile

The block is machined to a 20 mm depth and single PCIe slot width, making it correct for Blackwell server edition cards deployed in chassis where two-slot clearance is not available. Full-cover contact across GPU die, VRAM, and VRM is maintained within the reduced form factor.

G1/4″ Terminal Block

Two G1/4″ ports on the POM terminal block provide direct integration with EK-Pro Quick Disconnect kits and the full manifold range. EPDM O-ring sealing and pre-installed brass standoffs are included. A retention backplate is pre-fitted.

Pressure Envelope

Working pressure is 2 500 Pa. Maximum rated pressure is 30 000 Pa in loops containing an EK-Pro Pump Reservoir Manifold, and 75 000 Pa in all other configurations. Figures are consistent across the GPU water-block family.
