With a thickness of 44mm, the EK-Quantum P Series Surface radiators are the absolute all-rounders for low noise and high performance across the entire fan operational range. Equipped with a total of four G1/4“ threaded connection ports, it provides additional versatility during the loop planning process, while the fifth G1/4“ port located on the end-tank is an irreplaceable feature when it comes to draining the loop and air bleeding. A total of sixteen 2mm-wide copper tubes across the entire radiator length assure optimal coolant flow, putting no stress on your cooling loop. High-grade non-louvered copper fins with 18 FPI density provide the best balance between thermal transfer and air resistance, enabling optimal performance even at low-speed fan operation. To maximize cooling performance, a Push/Pull setup can be utilized on any P Series EK-Quantum Surface radiator.
The EK-Quantum Surface P series radiator maximizes performance by utilizing a new radiator core. When comparing core to core performance, the Surface P radiator performs up to 10% better than its predecessor, the CoolStream PE, thanks to its enhanced fin structure and optimized 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 120mm fans that have 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 aluminum 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 black paint, while the fins themselves have a special black matte coating with a high thermal conductivity coefficient.
Set into the aluminum accent end caps are modular plugs and extenders 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.
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.
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 at the same time making the disassembly process very easy and 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.
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. This means you will be able to add multiple radiators to your cooling loop using only a single pump (D5 or DDC). The radiators are also 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 in the case to breathe properly.
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, as well as 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 than ever before.
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).

EK-Quantum Momentum Aorus Z490 Master D-RGB is the new Quantum Line monoblock specifically engineered for the Gigabyte® Aorus Z490 Master motherboard. Featuring the latest generation Velocity cooling engine with low restriction and high performance, this monoblock is equipped with a 3-pin D-RGB (addressable) LED strip and it offers unparalleled aesthetical customization alongside superior performance! The D-RGB LED in the monoblock is compatible with Gigabyte RGB Fusion 2.0 which offers a full lighting customization experience.
EK® Momentum series monoblocks utilize the 5th generation of the award-winning EK® CPU water block cooling engine, further tweaked for performance and optimal coolant flow! This water block directly cools Intel® 1200 socket-type CPU, as well as the power regulation (MOSFET) module. Liquid flows directly over all critical areas, providing the enthusiasts with a great solution for high and stable overclocks. Like with every EK monoblock, the EK-Quantum Momentum Aorus Z490 Master features a high flow design and it can be easily used with the system using weaker water pump or lower pump speed settings as well. The Momentum monoblock also comes with sophisticated addressable D-RGB lightning which connects to a standard 3-pin 5V D-RGB header on the motherboard.
The purest nickel-plated copper available on the market is used for the cold plate which is precisely machined to a dense micro-fin structure. The nickel-plated brass screw-in standoffs are pre-installed and allow for easy installation. Top of the monoblock features a CNC machined glass-like cast acrylic top piece.
The new cooling engine is characterized by the top-integrated jet nozzle which is combined with a thicker jet plate allowing a more precise bow control. The simplified water block structure offers a more optimized coolant flow and easier maintenance, while the jet plate ensures the best contact surface for the CPU.
Unlike other solution on the market, this is a true one-piece, sturdy and reliable liquid cooling product which requires only two connector fittings for proper operation. The enclosed thermal pad is used on voltage regulator modules to improve stability, performance, and prolongs the lifespan of the motherboard. For the CPU, please use the enclosed (electrically non-conductive) thermal grease EK-TIM Ectotherm.
The block is already equipped with 3-pin 5V Addressable D-RGB LED strip which is compatible with the Aorus Z490 Master 3-pin 5V D_LED (Addressable LED Strip) headers. This product is also compatible with D-RGB controllers that support the pinout: +5V, D, Blocked, Ground. The arrow marking on the 3-pin LED connector is to be aligned with the +5V marking on the D_LED (Addressable LED Strip Headers)
