Alphacool NexXxoS XT45 Quad 480 mm / 560 mm. 280 x 280 x 45 mm pure cooling surface for four 120/140 mm fans on one side or eight fans on both sides.

Uncompromising in the
choice of material As usual, Alphacool also uses pure copper for the NexXxoS XT45 Quad Radiator. The antechambers, the water channels and the cooling fins are made of copper and are unique worldwide. As a result, Alphacool radiators have been among the most popular and best on the market for many years, which is the perfect basis for any water cooling.

Full cooling performance
In order to maximize the performance of a radiator, Alphacool digs deep into its bag of tricks. It starts with copper. With a thermal conductivity of 400 W / (mK) for copper compared to 236 W / (mK) for aluminum, the winner is certain. In addition, there is the special fin density. Alphacool is one of the oldest water cooling companies and has carried out countless laboratory tests. The result, especially for such large radiators, is a fin spacing of 12 FPI. As a result, the air flow is hindered relatively slightly, since the air can slide through even with very little pressure. This makes the radiator ideal for fans with low speed. The cooling performance does not suffer from this, on the contrary. In order to use the airflow optimally, all cooling fins have small flaps. These are tiny wings which direct the airflow in the desired direction. In the case of the radiators, these are barely 1 mm high, but still ensure controlled air turbulence in order to increase cooling performance and minimize flow noise.
