GPU Water Block ek water blocks EK-Quantum Vector³ FE RTX 5090 — Acrylic Top

ek water blocks EK-Quantum Vector³ FE RTX 5090 — Acrylic Top is a full-cover GPU water block engineered for NVIDIA RTX 5090 Founders Edition graphics cards. The block provides direct liquid cooling for the GPU die, dedicated memory modules and voltage regulation modules, integrating an acrylic top for visual clarity and compatibility with RGB setups. Designed for custom closed-loop and open custom-loop systems, it reduces operating temperatures and acoustic output compared with standard air cooling while maintaining reliable thermal transfer for high-performance desktop builds.

Advantages

The acrylic-top construction offers a clear view of coolant flow and is compatible with lighting accents while preserving structural rigidity. The block features optimized coolant channels and a precision-machined cold plate to ensure uniform contact with the GPU die and effective heat removal from VRAM and VRM areas. Using a dedicated GPU water block enables lower peak temperatures, more consistent thermal performance under sustained load and quieter system operation due to reduced fan speeds on the primary cooling loop.

Suitable for

• Custom liquid cooling loops in high-performance gaming and workstation PCs
• Overclocked RTX 5090 Founders Edition builds requiring enhanced thermal management
• Silent or low-noise desktop systems where acoustic reduction is a priority
• Showcase systems that benefit from visible coolant routing and RGB integration

Key specifications

• Compatibility: specifically designed for NVIDIA RTX 5090 Founders Edition PCB layout
• Top material: acrylic (transparent) for visual access to coolant flow
• Cold plate: precision-machined metal contact surface for GPU, VRAM and VRM cooling
• Porting: G1/4 threaded ports for standard liquid cooling fittings and tubing
• Mounting: full-cover mounting solution with included bracket hardware for secure attachment
• Flow design: optimized micro-channel cooling pathways for efficient heat transfer

How to use

Mount the water block following the manufacturer's installation guide, ensuring the RTX 5090 Founders Edition PCB is the correct revision for this model. Prepare the system by draining and cleaning the loop if replacing an existing cooler, apply the recommended thermal interface material to the GPU die and align the block over the board so that mounting holes and ports match. Tighten mounting screws evenly in a cross pattern to achieve uniform pressure. Connect inlet and outlet fittings to the loop using compatible G1/4 fittings and ensure proper tubing routing to maintain consistent coolant flow through the block.

Regularly inspect fittings and tubing for leaks and check coolant condition periodically. Use corrosion-inhibited and compatible coolant fluids and avoid mixing different coolant chemistries. During initial run-in, operate the pump with the system powered off for fans to remove air from the loop, then monitor temperatures under controlled load to confirm correct installation and leak-free operation.
