EK-Quantum Surface S360 - Black 3831109838198 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.
