## Overview

The EK-Pro GPU WB A100 Rack Nickel + Inox is a high-performance water block for the NVIDIA® A100 GPU in rack-mount form. The Open Split-Flow cooling engine covers the GPU die, VRAM, and VRM directly with low hydraulic flow restriction, making it compatible with modest pump setups in high-density rack deployments.

Construction uses a CNC-machined nickel-plated copper base and stainless-steel top with EPDM O-ring sealing. A 45° angled terminal block carries two G1/4″ ports for integration with EK-Pro QDC kits and manifolds. The retention backplate provides structural rigidity and passive cooling to the PCB VRM area.

A side-mounted standoff ensures secure GPU mounting during chassis movement – relevant in datacentre environments where chassis are frequently transported between rack positions.

### Full-cover cooling

GPU die, VRAM, and VRM cooled directly under one Open Split-Flow engine with low hydraulic restriction.

### Open Split-Flow engine

Minimises flow restriction – compatible with weaker water pumps in high-density rack deployments.

### Nickel + stainless construction

CNC-machined nickel-plated copper base and stainless-steel top for corrosion resistance and loop longevity.

### QDC kit compatible

45° angled terminal block with two G1/4″ ports integrates directly with EK-Pro QDC kits and manifolds.

### Retention backplate

Provides structural rigidity and passive cooling to the PCB VRM area on the reverse of the board.

### Side-mounted standoff

Ensures secure GPU mounting during chassis movement in datacentre transport and rack repositioning.

### Open Split-Flow

The Open Split-Flow geometry divides the coolant path symmetrically over the die face before recombining it downstream, producing an even pressure profile across the GPU silicon, VRAM, and VRM zones. Low hydraulic restriction maintains compatibility with a wide range of pump specifications.

### 45° angled terminal · side-mounted standoff

The 45° angled terminal block positions the G1/4″ ports to route tubing within the rack chassis envelope. The side-mounted standoff provides a brace point that prevents PCIe slot flex during chassis transport – a practical requirement in datacentre environments where servers are regularly moved between rack positions.

### 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 published at the supplier level and are consistent across the GPU water-block family.
