## Two form factors, two block types

### Full-height PCIe

Workstation

Side-terminal design with 45° angled port block. Optimised for tower and desk-side workstations where thermal envelope matters more than vertical clearance. Integrated I/O plate for stability during transport.

Occupies ≥ 2 PCIe slot widths

### Slim, single-slot

Server rack

Rack-style terminal routes plumbing vertically for 1U chassis clearance. Single PCIe slot width with integrated I/O plate. FHFW-compatible. Pairs with EK-Pro QDC kits for single-card serviceability inside a populated chassis.

Occupies 1 PCIe slot width

## Every block in this family shares the following.

| Specification | Value |
| --- | --- |
| Cooling engine | Open Split-Flow or dual-pass, depending on card. Covers GPU die, VRAM, and VRM under the same block. |
| Materials | Nickel-plated electrolytic copper base · stainless steel top · POM Acetal terminal block · EPDM O-rings |
| Mounting | Backplate with pre-installed brass standoffs · side-mounted standoff for transport rigidity |
| Ports | 2 × G1/4″ · integrates with EK-Pro QDC kits and manifolds |
| Working pressure | 2 500 Pa working · 30 000 Pa max in loops with EK-Pro Pump Reservoir Manifold · 75 000 Pa max otherwise |
| Operating temperature | 5 – 60 °C |
