Decent price, kept me updated with progress, well packed (and they chucked in some sweeties!) and good delivery. Great service overall.Read on Google

With a thickness of only 30mm, the EK-Quantum S Series Surface radiators are ideal for space-constrained cases. Despite the reduced thickness, they deliver exceptional performance at very low and medium fan speeds. A total of 16 copper 2mm wide tubes across the entire length of the radiator assure optimal coolant flow putting no stress on your cooling loop. High-grade non-louvered copper fins with 20 FPI density provide the best balance between thermal transfer and air resistance for optimal performance even at low-speed fan operation. A Push/Pull setup on an S Series EK-Quantum Surface radiator is not something EK would recommend since it will not bring a proportional performance increase. If more cooling power is needed, adding additional radiators is the way to go.
The EK-Quantum Surface S series radiator maximizes performance by utilizing a new radiator core. When comparing core to core performance, the Surface S radiator performs up to 20% better than its predecessor, the CoolStream SE, due 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.
Each radiator part is fully black - Frame, end caps, port adapters, fins, and even the screws. The Black Edition of the EK Quantum Surface S240 features exceptional build quality, advanced liquid cooling capabilities, and a user-friendly installation process. With its top-of-the-line materials and precision engineering, this product will provide long-lasting performance and reliability for even the most demanding PC users. Plus, the sleek and minimalist appearance is perfect for those who want a high-performance liquid cooling solution without sacrificing style.
The blacked-out design allows the product to blend seamlessly into any PC build, making it the perfect addition for those who want a clean and minimalist aesthetic. With its bold and stylish look, the Black Edition of the EK Quantum Surface S240 is sure to turn heads and elevate any PC setup to the next level.
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).
