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

The EK-Quantum Vector³ Astral RTX 5090 – Plexi represents the pinnacle of high-performance liquid cooling, designed specifically for the ASUS ROG Astral GeForce RTX™ 5090 32GB GDDR7 and ASUS ROG Astral GeForce RTX™ 5090 32GB GDDR7 OC Edition. Featuring an improved, larger cooling engine, higher-performance thermal pads, and a new gasket design to optimize reliability and aesthetics, this water block ensures exceptional cooling efficiency, even under extreme workloads.

Enhanced Cooling Engine for Unmatched Performance

The revised cooling structure of the Vector³ Astral RTX 5090 maximizes heat transfer with an expanded fin array and optimized coolant flow paths. It actively cools the GPU core, VRAM, power stages, and passively cools PCB hotspots through the included backplate.

• Optimized Open Split-Flow Cooling Engine – Superior flow distribution for uniform cooling and reduced restriction.
• Low Hydraulic Restriction – Enables compatibility with both high- and low-flow pump systems.
• Ideal for Overclocking & High-Load Applications – Keep your GPU running at peak performance with sustained low temperatures.

Premium Materials and Precision Engineering

Built with high-quality components for durability and peak performance:

• Nickel-Plated Electrolytic Copper Coldplate – Maximizes thermal conductivity and longevity.
• CNC-Machined Cast Acrylic Top – Showcases the coolant while offering a crystal-clear aesthetic.
• Black Anodized Aluminum Backplate – Increases cooling surface area and enhances structural integrity.
• Single O-Ring Seal Design – Reduces potential failure points for long-term reliability.
• New Gasket System – Prevents solid coolant particles from collecting between the coldplate and acrylic top, ensuring optimal performance.

Pre-Cut High-Performance Thermal Pads

The Vector³ Astral RTX 5090 comes with next-gen thermal pads that are partially pre-cut for seamless installation and optimized contact, allowing for superior heat dissipation from VRAM and power delivery components.

Included Full-Coverage Backplate

Every Vector³ Astral RTX 5090 water block includes a backplate, designed to:

• Passively cool PCB hotspots, including VRAM, core, and VRM sections.
• Provide a sleek, modern look with its black anodized aluminum finish.
• Simplify installation with pre-installed captive backplate screws, eliminating guesswork.

This L-shaped backplate profile seamlessly encloses the GPU for a clean, unified aesthetic while adding an additional layer of cooling performance.

EK-Matrix7 Support – For Perfect Loop Planning

The EK-Quantum Vector³ Astral 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.

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): 277 x 156 x 27 mm
• D-RGB LED Count: 14
• D-RGB Connector: 3-pin 5V digital LED header
• D-RGB Cable Length: 500 mm
