New EK-Pro GPU WB AMP/Trinity RTX 4090 - Nickel + Inox is a high-performance full-cover water block for Zotac AMP and Trinity Nvidia RTX™ 4090 graphics cards. It was specifically engineered to make the entire GPU and water block assembly as thin as possible, effectively taking up just one PCIe slot in width. The water block is equipped with a rack-style terminal, considerably reducing the assembly height and increasing its chassis compatibility.

EK-Pro AMP/Trinity NVIDIA RTX 4090 GPU Water Block

By spanning the entire PCB, the water block directly cools the GPU, VRAM, and VRM (voltage regulation module) as cooling liquid is channeled directly over these critical areas.

EK-Pro GPU WB AMP/Trinity RTX 4090 – Nickel + Inox water blocks use an Open Split-Flow cooling engine which proved to be a superior solution for GPU water blocks. It is characterized by low hydraulic flow restriction, meaning it can be used with weaker water pumps or pumps running on low-speed settings and still achieve top performance. The lowered coolant flow requirement makes it an ideal solution for multi-GPU workstations and servers. The jet plate and fin structure geometry have been optimized to provide even flow distribution with minimal losses and optimal performance even when used in reversed water flow scenarios.

EK-Pro AMP/Trinity NVIDIA RTX 4090 GPU Water Block Coldplate

The base of the water block is CNC-milled out of nickel-plated electrolytic copper, while its top is laser-cut out of industry-grade stainless steel. High-quality EPDM O-Rings ensure the sealing. The brass standoffs are already pre-installed and allow for a safe and easy installation procedure.

EK-Pro AMP/Trinity NVIDIA RTX 4090 Top Cover and I/O Bracket

The I/O plate is part of the water block top for added stability and protection of the graphics card. This means the stock I/O shield is replaced, adding more sturdiness to the whole assembly. The integrated single-slot I/O plate also benefits more compact workstation and server environments where space and PCIe slot spacing is a luxury. This design enables the card to occupy only one single PCIe x16 slot, leaving its surrounding slots available for other add-in cards.

EK-Pro AMP/Trinity NVIDIA RTX 4090 Passive Backplate

The aesthetic retention backplate improves the looks of the graphics card, as well as its structural rigidity while providing passive cooling for the backside of the PCB VRM area.

EK-Pro AMP/Trinity NVIDIA RTX 4090 Terminal

The EK-Pro AMP/Trinity RTX 4090 GPU water block features a POM-machined terminal block at the back with two G1/4” ports, allowing easy integration with EK-Pro QDC Kits and manifolds for high-compute density applications.
