## Long description

ek water blocks EK-Quantum Vector³ Master for NVIDIA GeForce RTX 5090 is a full-cover GPU water block engineered for custom liquid-cooling loops. The block provides direct liquid contact with the GPU die, memory modules and voltage-regulation components to reduce operating temperatures and acoustic noise. The acrylic top offers visual access to coolant flow while the integrated addressable D-RGB lighting adds customizable illumination. A matching backplate is included to assist heat distribution and provide mechanical support to the graphics card.
Advantages
This water block offers full-cover cooling for GPU, VRAM and VRM, enabling more uniform heat removal compared with air cooling. The acrylic top allows visual inspection of coolant and flow, while the D-RGB lighting is compatible with addressable lighting ecosystems for synchronized effects. The included backplate helps dissipate heat from the rear PCB area and strengthens card rigidity. The product is designed for straightforward integration into standard custom loops and uses industry-standard G1/4" ports for fittings.
Suitable for
 High-performance NVIDIA GeForce RTX 5090 graphics cards in custom liquid-cooling loops
 Silent workstation and gaming PC builds requiring reduced GPU operating temperatures
 Enthusiast systems where component visibility and RGB customization are desired
 Overclocking setups that need improved thermal headroom for sustained loads
Key specifications
 Full-cover design cooling GPU die, memory modules and VRM
 Acrylic top for visual coolant viewing
 Addressable D-RGB illumination compatible with standard controllers
 Included backplate for improved heat distribution and mechanical support
 Standard liquid-cooling thread compatibility (G1/4")
 Precision-machined cold plate surface for optimal thermal transfer
How to use
Install the EK-Quantum Vector³ Master water block following the manufacturer’s installation instructions and use the supplied mounting hardware and thermal pads or paste where indicated. Prepare your custom loop, drain and flush existing coolant if replacing an air cooler, then connect the block using appropriate fittings and tubing to the loop. Ensure all connections are tightened to specification, perform a leak test with the system powered off, and run the loop for a period to confirm stable coolant flow and correct RGB operation before normal use.
Usage recommendations
Use compatible, non-conductive coolant and maintain regular loop maintenance including periodic coolant replacement and system flushing. Verify compatibility with your specific RTX 5090 PCB variant prior to installation and follow torque specifications for mounting screws to avoid PCB damage.
