EK-Quantum Surface X420M - White

For those who demand the most cooling power from an EK-Quantum Surface radiator, the 58mm-thick X Series is the right choice. These thick radiators benefit most from medium and high-speed fans or a Push/Pull setup. Equipped with four G1/4 "threaded connection ports, the X Series provides additional versatility during the loop planning process. The fifth G1/4 "port located on the end tank is an irreplaceable feature for draining the loop and air bleeding. Eighteen 2mm wide copper tubes across the radiator ensure optimal coolant flow, putting no stress on your cooling loop. High-grade non-louvered copper fins with 18 FPI density balance thermal transfer and air resistance best. EK doesn't recommend using slow-running fans on X Series EK-Quantum Surface radiators as they require adequate airflow to remove more heat than they absorb in their thick core.

EK-Quantum Surface premium radiators are built upon years of development and market research to deliver the best product that the market demands in every possible way. The finish of the materials, mechanical rigidity, and performance have all been brought to another level. Like all other Quantum Line products, EK's brand-new Surface radiators bring numerous performance improvements, including thermal performance, coolant flow restriction, and airflow restriction. 

With the supplied screws, this radiator is compatible with 140mm fans with a standard 25mm thickness. EK recommends using EK fans or similar ones with sealed-edge frames. This classic yet effective square shape of the fan casing provides optimal performance in either the pull (suction) or push (pressure) regime without any hydraulic losses, thus ensuring the optimal cooling capacity of your liquid cooling radiators. 

Thick, extruded aluminium end caps with a contrasting silver finish give the radiator a premium look and feel. They cover the internals and join the stamp-pressed side plates, creating a rigid structure that is pleasant to handle. The stainless-steel side plates are coated with durable semi-gloss white paint, while the fins have a special black matte coating with a high thermal conductivity coefficient. 

Multiport – The Choice of Ports is Yours

Set into the aluminium accent end caps are modular plugs and adapters that can be interchanged and configured by the user for optimal tube routing.?This multiport radiator has two additional G1/4 "threaded connection ports on the side and one extra port on the opposing end for air bleeding.  

M4 Screws – Standardized, Easy to Find 

Hard-wearing black M4 Philips round-headed screws are supplied for ease of use. In general use case scenarios, EK strongly suggests using only the included screws to avoid damage to the radiator itself. However, M4 screw compatibility allows the users to source longer screws if necessary. The cooling core is designed to cause no detrimental damage to the structural integrity of the radiator core even if the customer uses longer screws accidentally, as they will collide only with the fins. 

Easy Disassembly – DIY Modding Dream 

The EK-Quantum Surface range was designed and executed as a modular product range rather than individually sized radiators. Such a design achieves immaculate fitment and continuity in appearance while simultaneously making the disassembly process straightforward. Catering to the DIY modding community is something EK has always been supporting, so painting and modifying your Surface radiator will be a breeze.  

Loop Friendly – Don't Worry About Your Pump 

The internal structure design of the radiators was executed with low flow restriction in mind, providing no unnecessary stress on the rest of the cooling loop. You can add multiple radiators to your cooling loop using only a single pump (D5 or DDC). The radiators are airflow-friendly and low-restriction, allowing lower fan speed operation to achieve the same performance. Low airflow restriction keeps the case well-ventilated and allows other radiators to breathe correctly.   

EK-Matrix7 Compatible – For the Cleanest Tube Runs

Since any custom liquid-cooling loop is built from multiple EK products, the most valuable distinction in aesthetics and ease of use comes from the sum of all the parts. To address this, EK initiated Matrix7, a system that standardizes products' dimensions, port position and spacing. In so doing, we are making the liquid cooling loop assembly more intuitive and having a clean set of parallel tubing runs easier. 

All EK-Quantum Surface radiators are EK-Matrix7 compatible, which means they effortlessly integrate with Reflection², the second generation of Quantum distro plates. This enables the user to easily swap and upgrade between S, P, and X series Surface radiators within the same case (provided the case supports thicker radiators in the same position).
