Featuring a slim 30mm profile, 16 copper tubes, and 20 FPI copper fins, it delivers outstanding thermal efficiency at low fan speeds. Its modular design with removable aluminum shrouds offers both style and customization, making it a top choice for millennial pros seeking silent, powerful cooling solutions. ## 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 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.
