The NexXxos Full Copper HPE Radiator uses the same materials as the previous NexXxos models, but technically goes a step further. Thanks to the compacted inner construction, the number of water channels and copper fins could be increased. This means that a larger volume of water is in direct contact with the cooling fins and the heat transfer is greatly improved. Technical data: radiator L x W x H 270 x 120 x 20 mm.
