GPU water block ek water blocks EK-Quantum Vector3 Astral RTX 5090 D-RGB Acrylic

The EK-Quantum Vector3 Astral RTX 5090 D-RGB Acrylic is a full-coverage GPU water block designed for NVIDIA GeForce RTX 5090 graphics cards. Constructed with an acrylic top and precision-machined coldplate, this component provides direct liquid cooling to the GPU and surrounding PCB area specified by the card manufacturer. Integrated D-RGB lighting allows for customizable illumination when connected to compatible RGB controllers. The block is intended for installation in custom closed-loop water-cooling systems to improve thermal performance and reduce acoustic output compared with air cooling.

Advantages

This acrylic GPU water block delivers efficient heat transfer through a finely engineered coldplate that contacts the GPU die and critical VRM and memory components covered by the block’s layout. The transparent acrylic top offers visual access to coolant flow while the D-RGB lighting enables system-level color coordination. Designed for compatibility with the RTX 5090 PCB layout specified by the manufacturer, the block simplifies integration into custom loops and supports sustained high-load operation with lower temperatures and quieter system noise.

Suitable for

• High-performance gaming PCs seeking lower GPU temperatures and reduced fan noise
• Workstations running GPU-intensive workloads such as rendering and simulations
• Custom liquid-cooling loops where full-cover GPU cooling and aesthetics are required
• Users who want integrated D-RGB lighting synchronized with other components

Key specifications

• Material: acrylic top with precision-machined copper or nickel-plated coldplate (depending on variant)
• Cooling type: full-cover liquid cooling for GPU and specified PCB area
• Lighting: addressable D-RGB compatible with standard 3-pin D-RGB headers
• Mounting: multi-point mounting hardware included for the matching RTX 5090 PCB layout
• Fluid channels: designed for optimal flow distribution across GPU die and nearby components

How to use

Install the water block by first preparing the graphics card according to the manufacturer’s service instructions and removing any stock cooling solution if required. Apply thermal interface material to the GPU die and other contact surfaces as specified by EKWB, align the block to the card’s mounting holes, and secure it with the supplied hardware. Connect the D-RGB cable to a compatible header for lighting control. Integrate the block into a closed-loop water-cooling system using appropriate fittings and tubing, ensure proper loop bleeding, and verify leak-free operation before regular use.

Recommendations

Use coolant compatible with copper and acrylic components and follow EKWB guidelines for maintenance intervals. During installation, handle the PCB and connectors with ESD precautions, torque mounting screws evenly, and confirm compatibility with the RTX 5090 PCB revision. Periodically inspect fittings and coolant condition, and flush the loop as recommended to maintain peak cooling performance and lighting functionality.
