With a thickness of 44mm, the EK-Quantum P Series Surface radiators are the absolute all-rounders for low noise and high performance across the entire fan operational range. Equipped with a total of four G1/4“ threaded connection ports, it provides additional versatility during the loop planning process, while the fifth G1/4“ port located on the end-tank is an irreplaceable feature when it comes to draining the loop and air bleeding. A total of sixteen 2mm-wide copper tubes across the entire radiator length assure optimal coolant flow, putting no stress on your cooling loop. High-grade non-louvered copper fins with 18 FPI density provide the best balance between thermal transfer and air resistance, enabling optimal performance even at low-speed fan operation. To maximize cooling performance, a Push/Pull setup can be utilized on any P Series EK-Quantum Surface radiator. New and Improved The EK-Quantum Surface P series radiator maximizes performance by utilizing a new radiator core. When comparing core to core performance, the Surface P radiator performs up to 10% better than its predecessor, the CoolStream PE, thanks 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.
