On sale! (normally $65) The Alphacool NexXxoS XT45 X-Flow radiator features a 120mm design that's made for high flow rates. All main parts, not only the fins and channels, but the chambers are also made from copper. Separated chambers give the coolant a clear direction, allowing high flow rates which improve the performance of the whole cooling loop. Flat chambers on the heat exchanger increase mounting flexibility thanks to the reduced overall length.
