EKWB EK-Quantum Vector 2 FE RTX 4090 GPU Water Block

Product Overview

The EKWB EK-Quantum Vector 2 FE RTX 4090 is a high-performance GPU water block designed for compatible RTX 4090 graphics cards. It provides comprehensive liquid cooling for key heat-generating components, including the GPU, VRAM, power stages, and PCB hotspots.

Built around a substantial 10mm thick copper cold plate, the water block combines effective thermal transfer with a robust construction. Its integrated digital RGB lighting adds a customizable visual element to high-end custom water-cooled PC builds.

Full-Coverage GPU Cooling

The EK-Quantum Vector 2 FE is engineered to cool more than just the GPU core. Its full-coverage approach actively targets the GPU, VRAM, power stages, and PCB hotspots, helping manage temperatures across critical areas of the graphics card.

This makes it well suited to powerful gaming and enthusiast systems where consistent thermal management is important.

Thick Copper Cold Plate

At the heart of the water block is a 10mm thick copper cold plate, providing a substantial thermal interface between the graphics card components and the cooling system.

The thick copper construction contributes to a durable and robust water-block assembly while providing an effective pathway for transferring heat into the liquid-cooling loop.

Robust Acetal Terminal Design

An acetal terminal is attached directly to the copper cold plate, creating a solid and integrated assembly. This construction provides a clean connection point for the liquid-cooling loop while complementing the water block’s premium design.

Digital RGB Lighting

The water block features digital RGB lighting, allowing builders to add customizable illumination to their GPU cooling setup.

It is an ideal visual addition for RGB-focused gaming PCs and custom showcase builds.

Compact Water Block Design

Despite providing active cooling for multiple GPU components, the water block maintains a relatively compact profile with dimensions of 272.5 × 155 × 27mm.

Its streamlined design allows it to integrate neatly into custom liquid-cooling configurations while providing broad component coverage.

Ideal For

• Custom water-cooled gaming PCs
• RTX 4090 liquid-cooling builds
• High-performance enthusiast systems
• GPU-focused custom loops
• RGB showcase PC builds
