EK-Quantum Velocity³ 1700/1851/AM5 Plexi CPU Water Block

EK-Quantum Velocity³ 1700/1851/AM5 - Plexi

Upgrade your custom loop with the EK-Quantum Velocity³ 1700/1851/AM5 - Plexi, a high-performance CPU water block engineered for AMD AM5 and Intel LGA 1700/1851 platforms. The Velocity³ Plexi is the successor to the Velocity² series, featuring an advanced, socket-optimised cooling engine with precision microfin geometry and calibrated mounting pressure, delivering up to a 2°C improvement in thermal efficiency for demanding gaming, overclocking, and workstation applications. Its nickel-plated copper cold plate ensures superior heat transfer and long-term durability, while the CNC-machined transparent Plexi top allows users to showcase their coolant, D-RGB lighting, and custom loop aesthetics without compromising structural integrity. A modular design enables internal component rotation for optimised heat spreader alignment and flexible port positioning, and the included AMD and Intel mounting brackets provide seamless cross-platform compatibility. Fully EK-Matrix7 compliant, the Velocity³ Plexi maintains consistent 7mm height and port spacing standards, simplifying loop planning and reducing tube-bending complexity. Combining elite cooling performance, premium materials, and visual customisation, the EK-Quantum Velocity³ Plexi is built for enthusiasts who demand both precision and style in their liquid cooling setups.

Precision Cooling for AM5 & LGA 1700/1851

Engineered specifically for modern AMD AM5 and Intel LGA 1700/1851 CPUs, the Velocity³ delivers optimised contact pressure and refined internal geometry for maximum heat transfer and up to 2°C improved performance over the previous generation.

Next-Gen Thermal Efficiency

An advanced microfin cooling engine and nickel-plated copper cold plate work together to rapidly draw heat away from high-core-count processors ideal for gaming, overclocking, and workstation workloads.

Modular Design for Loop Optimisation

Built for enthusiasts, the modular construction allows internal rotation for improved heat spreader alignment and flexible port positioning, making custom loop routing cleaner and easier.

Cross-Platform Ready

Both AMD and Intel mounting brackets are included in the box, allowing seamless platform compatibility without additional purchases.

Premium Plexi Finish

The Plexi version is crafted with a nickel-plated copper cold plate for superior thermal conductivity, paired with a CNC-machined transparent acrylic top. This combination delivers exceptional performance while showcasing the coolant flow, making it a centerpiece for any custom build.

EK-Matrix7 Compatible

Designed to EK-Matrix7 standards with 7mm height and port spacing increments, simplifying loop planning, improving alignment, and reducing tube-bending complexity.
