EKWB EK-Quantum Magnitude CPU Water Block Lignum Edition, AM4, Walnut

EK-Quantum Magnitude - AM4 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 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 socket processors. It features all the perks of EK-Quantum Magnitude 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.

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 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 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.
