Features

EK-Quantum Velocity³ 1700/1851/AM5 - Plexi
The EK-Quantum Velocity³ 1700/1851/AM5 - Plexi is a high-performance CPU water block designed for AMD AM5 and Intel LGA 1700/1851 platforms. Built on EK's legacy of award-winning cooling solutions, the Velocity³ Plexi combines cutting-edge technology, superior materials, and exceptional aesthetics to deliver unmatched cooling performance for PC enthusiasts and modders.
Advanced Cooling Engine
The Velocity³ features a next-generation cooling engine tailored to AMD and Intel platforms. Its optimised internal geometry and precise mounting pressure ensure maximum heat transfer efficiency. Compared to its predecessor, the Velocity², the Velocity³ achieves up to 2°C improvement in thermal performance, offering top-tier cooling for demanding workloads.

Modding-Friendly and Customisable
The Velocity³ water block is designed with versatility in mind, featuring a modular construction that allows for internal component rotation. This enables users to adjust the heat spreader alignment and port positions for an optimal setup in their custom loop. Additionally, new mounting brackets have been engineered for effortless clipping on and off. Both AMD and Intel mounting brackets are included in the box, allowing seamless transitions between platforms without the need for additional accessories. This flexibility ensures compatibility with a wide variety of systems while enabling easy loop optimisation.

Premium Materials and Design
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 centrepiece for any custom build.
Key Features:
- Socket-Specific Cooling: Engineered for AMD AM5 and Intel LGA 1700/1851 sockets.
- Thermal Efficiency: Delivers up to 2°C lower temperatures compared to the Velocity² series.
- Customisable Setup: Rotate internal components for optimised heat spreader alignment and port positioning.
- Premium Build Quality: Nickel-plated copper cold plate with a durable crystal-clear Plexi top.
- Minimalist Aesthetic: Sleek design enhances the visual appeal of any PC build.
Designed for Modders and Enthusiasts
The Velocity³ Plexi is the ultimate solution for those who demand superior performance and impeccable design. Its transparent top highlights the beauty of liquid cooling, making it an ideal choice for showcase builds.
Whether you’re optimising for gaming, overclocking, or content creation, the EK-Quantum Velocity³ Plexi sets the standard for next-generation cooling.
EK-Matrix7 Compliant
The EK-Quantum Velocity³ is an EK-Matrix7 compatible product. The EK-Matrix7 is a product raster that is bound to set a new standard. EK is adding a new dimension to PC liquid cooling, where the height of products and the distance between ports are managed by increments of 7mm. This improves product alignment and reduces the time spent planning the loop and bending tubes. Through the meticulous planning of EK products, building a liquid-cooled PC becomes easy and fun, just like toy bricks.

AMD Ryzen™ 7 9850X3D Compatibility
The EK-Quantum Velocity³ 1700/1851/AM5 is fully compatible with the AMD Ryzen™ 7 9850X3D and the AM5 platform. Designed as a high-performance, multi-socket CPU water block, it supports both AMD AM5 and Intel LGA 1700 / 1851 platforms.
In the AMD configuration, it is precisely tuned for Ryzen™ processors, targeting the CPU hotspot location to deliver maximum thermal performance under sustained gaming and high-load workloads.
Please Note:
- This product should NOT be installed with any aluminium liquid cooling parts.
- The use of specifically engineered coolants that contain corrosion, scale, and biological inhibitors is mandatory to prevent damage to your nickel-plated water block! EK is offering a selection of such products in the coolants section.
- The arrow marking on the 3-pin LED connector is to be aligned with the +5V marking on the D-RGB(A-RGB) header.
- The mounting screws are engineered with a hard-stop design, once the screw reaches the end of the thread, stop applying more force.
