For those who demand the most cooling power out of an EK-Quantum Surface radiator, the 58mm-thick X Series is the right choice. These thick radiators will benefit the most from medium and high-speed fans or even a Push/Pull setup. Equipped with a total of four G1/4" threaded connection ports, the X Series provides additional versatility during the loop planning process. 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 ensure 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. EK doesn't recommend using slow-running fans on X Series EK-Quantum Surface radiators as they require adequate airflow to remove more heat than they absorb in their thick core. Set into the aluminum accent end caps are modular plugs and extenders that can be interchanged and configured by the user for optimal tube routing. This multiport radiator has two additional G1/4" threaded connection ports on the side and one extra port on the opposing end for air bleeding. Dimensions: 325 x 145 x 58mm (L x W x H) Weight: 1.93kg FPI: 18 Port threads: 5x G1/4" Fan compatibility: 140x140x25mm fan Pressure tested: 1bar Enclosed: - EK-Quantum Surface X series radiator - 8x Phillips Slotted M4x30mm for 25mm thick fans - 8x Phillips Slotted M4x5mm for mounting the radiator directly to the case - 6mm steel Allen (Hex) key - 9mm steel Allen (Hex) key Model: 3831109838853
