EK-Pro GPU WB AMP/Trinity RTX 4090 – Ni + Inox is a high-performance full-cover water block for the ZOTAC NVIDIA GeForce RTX™ 4090 AMP Extreme Airo, Trinity, and Trinity OC graphics cards. The water block is a liquid cooling solution that spans the entire card length, cooling all critical components. It directly cools the GPU, VRAM, and the VRM (voltage regulation module) as cooling liquid is channeled directly over these critical areas.

Compatibility list:
EK-Pro GPU WB AMP/Trinity RTX 4090 – Ni + Inox water blocks use an Open Split-Flow cooling engine design that has proven to be a superior solution for GPU water blocks. It is characterized by low hydraulic flow restriction, which means it can be used with weaker water pumps or pumps running on low-speed settings and still achieve top performance.

The jet plate and fin structure geometry have been optimized to provide an even flow distribution with minimal losses and optimal performances even when used in reversed water flow scenarios.
The base of the block is CNC machined out of nickel-plated electrolytic copper, while the top is laser-cut out of industry-grade stainless steel. High-quality EPDM O-Rings ensure the sealing. The brass standoffs are pre-installed and allow for a safe and easy installation procedure. For added stability and protection for the graphics card, the I/O plate is designed to be a part of the water block top itself, which means that the block replaces the stock I/O shield and adds more sturdiness to the whole assembly.

The aesthetically pleasing retention backplate improves your graphics card’s looks and structural rigidity while providing passive cooling to the backside of the PCB VRM area.
This version of the EK-Pro AMP/Trinity 4090 GPU water block features a 45° angled terminal block with two G1/4” ports, enabling easy integration with EK-Pro QDC kits and manifolds for high compute density applications.

- Materials: Nickel-plated copper and stainless steel
Enclosed:
- EK-Pro GPU WB AMP/Trinity RTX 4090 - Ni + Inox workstation and server-grade water block
- Retention backplate
- Mounting mechanism with screw-in brass standoffs
- Necessary mounting screws, nuts, and washers
- Thermal Interface Material
A premium aesthetic terminal cover for EK-Quantum Scalar terminals, EK-Quantum Scalar accessories like the Flow Indicator, and a replacement cover for stock GPU terminals as well.
The cover is machined out of a solid piece of aluminum which is then black anodized to give it a premium look and feel. The cover can be attached quickly and easily by using the integrated pin screws located on the backside of the terminal cover.

The prime purpose of the product is to provide a terminal cover for users with EK-Quantum Vector RE RTX 3080/3090, EK-Quantum Vector Trinity RTX 3080/3090, EK-Quantum Vector Trinity RTX 3070, EK-Quantum Vector Strix RTX 3080/3090, and similar GPU water blocks which have a single piece terminal, which is then replaced with an EK-Quantum Scalar Flow Indicator. The EK-Quantum Vector Terminal Cover will provide an aesthetically cover for the screws, which blends in with the water block and flow indicator perfectly.
In the same way, the EK-Quantum Vector Terminal Cover can provide an aesthetical shroud for the screws for multi GPU setups using any of the EK-Scalar Dual or EK-Scalar Quad terminals.
Finally, any user who wishes to reduce the number of RGB LED sources in his PC, can use the EK-Quantum Vector Terminal Cover to replace the stock plastic cover on water blocks that have the two-piece terminal design (acetal terminal + plastic cover).
Technical Specification:
- Material: Aluminum
- Finish: Black Anodization
Included:
- EK-Quantum Vector Terminal Cover
- Mounting screws
- 2mm Allen key
Compatibility:
- EK-Quantum Scalar Flow Indicator
- EK-Quantum Scalar Multi GPU terminals
