EK-Quantum Surface S280 Radiator, Supports 2x 140mm Fans, G1/4", Copper/Brass/Al

M4 Screws - Standard, 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. 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, 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. High-grade non-louvered copper fins with 20 FPI density provide the best balance between thermal transfer and air resistance. 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. This means you will be able to add multiple radiators to your cooling loop using only a single pump (D5 or DDC). International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions. 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 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.
