EKWB EK-Quantum Surface X280M - Radiator (white)

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 eighteen 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.
