Product information: NexXxoS Northbridge BlockThe new Northbridge copper cooler, based on the Alphacool NexXxoS cooler series has parallel-running channels in the PCF building method, these channels are milled perpendicularly to each other, by means of which the surface for the heat dissipation is drastically increased. The cross-channels are glass beaded, in order to increase the surface even more. This allows stable operation at extreme summer temperatures, highest overclocking potential and low noise at the same time. This cooler is conceived for the highest requirements. The copper surface of the cooler is flat and polished. The sealing between plexiglass and the copper cooling element is made by means of a durable O-ring. The attachment is made via the mounting drillings with bolts and springs, which are normally available at the AMD mainboards. The mounting components are made of stainless steel. For the attachment the mainboard must be demounted correspondingly. The G1/4" connections are suitable for all watercooling systems.
