All main elements, not just the fins and channels, but also the pre-chambers, are made of copper. This inherently provides a performance advantage where other radiators fall short. The internal structure is constructively on par with radiators from other manufacturers, and separate pre-chambers clearly define the path of the coolant. A high flow rate enhances the cooling performance throughout the entire system. The flat end chamber of the NexXxoS ST30 Full Copper 120mm also allows for more space during installation, as the overall length is reduced.
