With the HEATKILLER®V for AMD Radeon RX6800/6900XT we are taking the current HEATKILLER V generation to the next level with extensive optimisations. The full-cover water block draws on over 20 years of know-how in the development and production of high-performance water coolers. Featuring unique highlights, the latest version of the HEATKILLER® V demonstrates what is technically feasible.
Significant improvements over its predecessor:
Through an increased number and the special arrangement of the cooling fins, we were able to massively increase the cooling performance and thereby improve the most important area of the cooler. The cooler base is milled from a solid copper block and covers all relevant components. The innovative dual-layer inflow disperses the water on two layers. This results in an inflow that is at least 30 percent higher compared to the previous generation.
The wide and symmetrically designed flow channels reduce dead spots (standing water) to a minimum and increase the flow rate. Overall this results in a maximum cooling capacity as well as in an increased flow rate of the HEATKILLER® V. Thanks to newly designed spacers, made of high-performance plastic (PEEK), the solid copper block is optimally isolated from the pcb.
Besides the technical innovations the cooler comes with an impressive appearance. The screwless cover makes the entire block look like it was made from one piece while the symmetrically designed channels further underline the cooler's appearance and make it a truly unique element in any mod. The nickel-acrylic version of the cooler features an integrated high-luminous aRGB LED strip as standard. This allows the HEATKILLER® V to be seamlessly integrated into the systems lighting concept.
We strongly recommend using the optionally available backplate to achieve the best visual appearance. Thanks to the unique manufacturing process, all electronic components are covered without sacrificing illumination.
The legendary Kryonaut thermal compound from Thermal Grizzly provides the best possible thermal conductivity. The pre-cut heat-conducting pads ensure exceptional cooling of the voltage converters. The pads can be removed without leaving any residues and thus offer the best mounting comfort.
Planned modifications:
We only use selected materials from renowned manufacturers such as EVONIK, whose original Plexiglas® GS we use. Even the metals, such as the high-purity copper, come from renowned brand manufacturers.
Production is carried out with the utmost care on our state-of-the-art CNC machinery in Waren. Many work steps are executed by hand and each product is brought to perfection according to the four-eyes principle.

The EK-Quantum Magnitude is the new ultimate bespoke CPU water block from EK® that brings the highest cooling performance with the lowest possible flow restriction. The 115x 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 die layout of Intel® 115x socket processors.
Different from any mounting structure used by other water blocks that are usually black and mundane plates, the design accentuates an integrated X-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 a minimalistic black top CNC machined out of durable POM acetal.
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 115x version features an insert that directs flow evenly over the CPU die which is used in combination with a cold plate geometry that is specific to 115x socket processors. One more feature of the Intel-based Magnitude CPU water block is the reversible insert that can accommodate easier tube routing. It allows the user to swap the inlet and outlet port, by simply rotating the brass insert piece by 180°.
The aesthetic interchangeable inner frame is also machined out of a single piece of white POM acetal which acts as a light dispersion element for addressable D-RGB LEDs. 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.
Elegantly concealed under the aesthetic inner frame is a LED strip boasting the incredible 30, individually addressable D-RGB diodes that shine outward and illuminate the white frame. The addressable D-RGB is using an industry-standard 3-pin 5V digital LED connector (Pinout: +5V, Data, Blocked, Ground).
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.
