EK-Quantum Magnitude - AM5 Lignum Edition – Walnut

EK-Quantum Magnitude - AM5 Lignum Edition – Walnut is a flagship bespoke CPU water block from EK® that brings the highest cooling performance with the lowest possible flow restriction. The AM4/AM5 version of the water block is using a specific combination of flow distribution insert, mounting pressure, and cold plate geometry tailored for the IHS and chiplet layout of AMD AM4/AM5 socket processors. It features all the perks of EK-Quantum Velocity² with the added bonus of a uniquely luxurious wooden cover. Each water block has a unique wood pattern that differs from every other water block that is made.

Lignum - The EK Signature Edition

The founder and owner of EK Water Blocks, Edvard König, discovered his passion for woodworking at a very young age and began his career in a workshop. That knowledge and enthusiasm ultimately led him to start designing and manufacturing the water blocks that we know today. It was only a matter of time before these two paths of his would collide and bring about something truly amazing.

EK Lignum, the signature edition of EK liquid cooling products is inspired by Mr. Edvard König’s love for woodwork and modern computer technologies, and is named after the Latin translation of the word ''wood''. It is the perfect symbiosis of the oldest natural building material and contemporary high-end cooling solutions. An unparalleled example of how your PC can reflect your lifestyle. EK Lignum and its wooden opulence can bring a feeling of comfort and warmth to your home while keeping your PC cool and silent for its maximum possible performance.

EK-Quantum Magnitude AM4/AM5

Different from any mounting structure used by other water blocks that are usually black and mundane plates, the design accentuates an integrated H-shaped, three-dimensional frame with premium finishes that firmly cradles the main body in place while the screws are morphed into a sophisticated design detail.

Specialized manufacturing techniques were deployed to create this truly unique product. Not a single component of Magnitude was made using mass production techniques; instead, every single piece was CNC machined separately, out of a solid piece of material. This version of the water block features a nickel-plated copper cold plate with an acetal top and a unique hand-crafted Walnut wood piece.

A CNC machined solid brass insert made it possible to significantly enlarge and optimize the cooling engine. Compared to previous generations of water blocks, the fin array has a 50% bigger surface area, all contained in a smaller footprint to ensure maximum compatibility even with mITX motherboards. The copper cold plate uses 0.40mm wide microchannels and 0.26mm thick microfins to maximize the thermal transfer with minimal flow restriction.

Since EK-Quantum Magnitude was engineered from the ground up for each specific socket, the AM4/AM5 version features an offset insert that directs more flow over the AMD Ryzen CPU chiplets with the I/O die still getting plenty of flow to keep it cool.

The aesthetic frame can be replaced with color-anodized aluminum variants that perfectly match EK-Quantum Torque fitting lineup or with a brass nickel-plated frame. The aesthetic interchangeable inner frames are sold separately.

The mounting mechanism is a three-dimensional H-shaped aluminum piece that makes the screws a seamless part of the water block. Strong edges and chamfers root this award-winning icon firmly among the EK-Quantum line. Did we say award-winning? 

EK-Quantum Magnitude is bearing the prestigious iF Design award for its bold and different approach to the CPU water block mounting mechanism.

The cold plate of the Magnitude water block is intentionally machined into a convex shape to align with the concave shape of the CPU IHS. However, if you are interested in a flat cold plate that works perfectly with lapped CPUs or aftermarket IHSs, EK is providing a special, flat bare copper as well as nickel-plated copper cold plates that are sold separately.

The Magnitude is supplied with an additional, thicker jet plate. If the user concludes that his CPU IHS is exceptionally concave (poor thermal paste spread after mounting), the curvature of the water block cold plate can be adjusted by using this secondary jet plate. It will make the center of the contact area bow by an additional 0.1mm outwards, for it to make better contact with the IHS.
