Description

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. The EK-Quantum Surface S series radiator maximizes performance by utilizing a new radiator core. Featuring 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. Thick, extruded aluminum end caps with a contrasting silver finish give the radiator a premium look and feel (aluminum does not come into contact with coolant). 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. 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 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. EK’s Matrix7 standardizes radiator dimensions, port locations, and spacing across compatible products, making liquid-cooling loops easier to plan, build, and upgrade. EK-Quantum Surface radiators are Matrix7 compatible and integrate seamlessly with Reflection² distro plates, simplifying tubing runs.

  • Awesome rad.
The best radiator made.

  • If you want the best of the best, EKWB has got you covered.
I like that these radiators are slightly thicker than their classic model counterparts, and the brushed aluminum shrouds on each end is a nice touch and they are easily removable if you're interested in painting them.
