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.
