EK-Quantum Vector³ FE RTX 5090 - Plexi GPU Water Block
The EK-Quantum Vector³ FE RTX 5090 - Plexi is a high-performance full-coverage GPU liquid cooling block engineered by EKWB for the NVIDIA GeForce RTX 5090 Founders Edition graphics card. Designed to replace the stock air cooler entirely, this block delivers advanced thermal management by channelling coolant directly over the GPU core, VRAM and power delivery stages, significantly reducing temperatures during high-load operation. Its precision-machined construction features a nickel-plated copper coldplate and a clear Plexi top that showcases the coolant flow and integrated addressable lighting, while premium sealing and pre-cut thermal pads ensure optimal contact with components. The block includes dual G1/4" threaded ports for standard loop connectivity, making it easy to integrate into custom liquid cooling systems, and is compatible with the EK-Matrix7 standard for simplified loop planning and aesthetic integration with RGB-capable cooling infrastructure. An included anodised aluminium backplate adds passive cooling and structural rigidity, and the addressable D-RGB lighting along the block edge integrates seamlessly with motherboard RGB sync technologies.
Optimised Cooling Engine
The Vector³ cooling core utilises an expanded fin array and precision coolant pathways designed to provide uniform distribution and low hydraulic restriction, ensuring efficient heat dissipation across the GPU, memory and power circuitry. This enhanced design supports stable temperature performance under sustained load and overclocked scenarios.
Premium Materials and Construction
The GPU block’s coldplate is machined from nickel-plated electrolytic copper for excellent thermal conductivity, and the CNC-machined Plexi top provides a clear view of the coolant flow and lighting effects. High-quality O-rings and a refined gasket system improve sealing and guard against debris build-up between the coldplate and top, enhancing long-term durability.
Backplate Support and Structural Reinforcement
A black anodised aluminium backplate is included to provide passive cooling for PCB hotspots such as MOSFETs, while also reinforcing the graphics card structure for added durability. The original Founders Edition lighting module is integrated into the backplate design, complementing the block’s aesthetic presence.
Professional Loop Integration with G1/4" Ports
The EK-Quantum Vector³ FE RTX 5090 - Plexi features dual G1/4" threaded ports for standard liquid cooling loop connection, enabling compatibility with a wide range of fittings, quick-disconnects and manifolds. Conforming to the EK-Matrix7 standard, this block ensures consistent port placement for streamlined routing and easier installation with distribution plates or reservoirs in complex custom loop layouts.
Addressable D-RGB Lighting
The block includes addressable D-RGB lighting integrated along its longest edge, compatible with mainstream motherboard RGB sync technologies via a 3-pin 5 V digital LED header, allowing users to customise lighting effects and harmonise them with other system components.
Important Notes:
1) Due to an immense variety of fittings/barbs available on the market and no prescribed standards, EK guarantee compatibility only for connectors from themselves.
2) Factory backplates are not compatible with this water block!
3) This product should NOT be installed with any aluminium Fluid Gaming parts!
4) The use of specifically engineered coolants that contain corrosion, scale, and biological inhibitors is mandatory to prevent damage to your nickel-plated water block.
5) This product is compatible with EK-Quantum Scalar² Terminals, but will no longer be Matrix7 compatible if stock terminal is replaced.
6) To leak test the EK-Quantum Vector³ water block, EK recommends 0.6 (+/-0.05) bars of pressure for 2 minutes.
