EK Water Blocks EK-Quantum Vector³ FE RTX 5090 - Plexi

The EK-Quantum Vector³ FE RTX 5090 – Plexi is a high-performance water block designed exclusively for the NVIDIA GeForce RTX™ 5090 Founders Edition. With a new, expanded cooling engine, improved thermal pads, and a precision-engineered gasket system, this block ensures optimal heat dissipation for the GPU core, VRAM, and power stages. The included backplate provides additional passive cooling, while EK-Matrix7 compatibility simplifies loop integration.

Optimized Cooling Engine for Maximum Efficiency

The Vector³ cooling engine is redesigned to maximize cooling performance while maintaining low restriction, ensuring optimal heat transfer across the GPU core, VRAM, and power delivery components.

• Enhanced Open Split-Flow Design – Even coolant distribution for superior thermal efficiency.
• Low Hydraulic Restriction – Works seamlessly with both high- and low-flow pump systems.
• Ideal for Overclocking & High Workloads – Maintains low temperatures for sustained peak performance.

Premium Materials and Precision Engineering

Crafted for durability and efficiency, the Vector³ FE RTX 5090 features:

• Nickel-Plated Electrolytic Copper Coldplate – Exceptional thermal conductivity for rapid heat dissipation.
• CNC-Machined Cast Acrylic Top – A crystal-clear aesthetic that showcases coolant flow.
• Black Anodized Aluminum Backplate assembly – Enhances cooling performance while providing a sleek, premium look. Additionally, the backplate assembly reinforces the overall structure, adding extra rigidity and stability to the complete setup.
• New Gasket System – Prevents solid coolant particles from collecting between the coldplate and acrylic top.
• O-Ring Seal – Ensures a secure, leak-resistant connection between key cooling components, maintaining optimal pressure and preventing coolant escape.

Pre-Cut High-Performance Thermal Pads

Designed for seamless installation and superior thermal contact, the pre-cut high-performance thermal pads ensure efficient heat dissipation across the GPU, VRAM, and VRM sections.

Included Full-Coverage Backplate

The EK-Quantum Vector³ FE RTX 5090 water block features a black anodized aluminum backplate assembly that enhances both cooling performance and structural integrity. Unlike standard backplates, this assembly provides passive cooling for the MOSFETs located on the backside of the block, ensuring stable power delivery under load. Additionally, the backplate serves as the main structural element of the GPU’s PCB, connecting all components and providing essential rigidity to prevent PCB flex and stress over time. The assembly also integrates the stock lighting module from the original cooler, illuminating the EK badge for a sleek and refined aesthetic.

EK-Matrix7 Support – For Perfect Loop Planning

The EK-Quantum Vector³ FE RTX 5090 follows EK-Matrix7, a standard that simplifies liquid cooling loop assembly by aligning ports and spacing components for intuitive tube routing.

• Perfect Integration with EK-Quantum Reflection² distribution plates.
• Straightforward Tube Bending & Loop Planning – Less time spent measuring and adjusting.
• Seamless Vertical & Horizontal GPU Mounting – A clean, professional look with minimal effort.

Whether mounting the GPU vertically or horizontally, Matrix7 ensures a hassle-free, precise build.

Rotatable Magnetic Covers

Sleek magnetic covers are used to conceal the terminal screws, which allows rotation of the branding when the GPU water block enclosures are inverted in the case or being used on a vertical GPU mount.

Addressable D-RGB Compatibility

Addressable D-RGB LED lighting is deployed on the longest edge of both top and backside water blocks for improved uniformity and brightness. The PCB and diodes are concealed inside a clean aluminum extrusion. The individually addressable RGB LED is compatible with popular RGB sync technologies from all major motherboard manufacturers. The arrow marking on the 3-pin D-RGB LED connector is to be aligned with the +5V marking on the D-RGB (addressable) header (Pinout: +5V | Data | Blocked | Ground).

Technical Specifications:

• Dimensions (L x H x W): 214 x 127 x 34 mm
• D-RGB LED Count: 11
• D-RGB Connector: 3-pin 5V digital LED header
• D-RGB Cable Length: 500 mm
