The EK Quantum Vector3 Astral RTX 5090 Plexi GPU Water Block features a nickel plated copper cold plate, a clear acrylic top and a black anodised aluminium backplate to provide efficient cooling for ASUS ROG Astral and Astral LC GeForce RTX 5090 graphics cards. The expanded cooling engine, pre-cut thermal pads and 14 D-RGB LEDs support effective heat dissipation and custom liquid cooling builds.
Features
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 optimise 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 maximises heat transfer with an expanded fin array and optimised coolant flow paths. It actively cools the GPU core, VRAM, power stages, and passively cools PCB hotspots through the included backplate.
- Optimised 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 Cold plate – Maximises thermal conductivity and longevity.
- CNC-Machined Cast Acrylic Top – Showcases the coolant while offering a crystal-clear aesthetic.
- Black Anodised Aluminium 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 cold plate 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 optimised 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 anodised aluminium 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 aluminium 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).
Please Note:
- Due to an immense variety of fittings/barbs available on the market and no prescribed standards, EK guarantee compatibility only with genuine EK connectors.
- Factory backplates are not compatible with this water block.
- This product should NOT be installed with any aluminium Fluid Gaming parts.
- The use of specifically engineered coolants that contain corrosion, scale, and biological inhibitors is mandatory to prevent damage to your nickel-plated water block! EK is offering a selection of such products in the coolants section.
- This product is compatible with EK-Quantum Scalar² Terminals, but no longer Matrix7 Compatible if stock terminal is replaced.
- To leak test the EK-Quantum Vector³ water block, EK recommends 0.6 (+/-0.05) bars of pressure for 2 minutes.
