Which fans? The 1080 Nova Radiator offers space for nine 120 mm fans on the mounting frame. If you want to operate the radiator passively, you can remove the mounting plate so as not to obstruct the natural air flow. Of course, the mounting plates for both types of fans can also be exchanged. So you have all the relevant freedom when mounting the fan.
Technical data: W x D x H: 378 x 360 x 46.5 mm. Net weight: 2588 g. Cooling fins material: copper. Material cooling channels: copper. Material of front chambers: copper. Outer housing: steel fins per inch: 12 connections: 3 x G1/4 inch thread size: fan mounting M3 fan size: 120 mm. Fan spaces: 9 Pressure tested: 0.8 bar
Rich cooling performance To maximise the performance of a radiator, Alphacool reaches deep into the box of tricks. The beginning is copper. With a thermal conductivity of 400 W/(mK) for copper compared to 236 W/(mK) for aluminium, the winner is certain. In addition, there is the special fin density. Alphacool is one of the oldest companies in the field of water cooling and has carried out countless laboratory tests. The result, especially for such large radiators, is a fin spacing of 12 FPI.
Can it be something more? Alphacool NexXxoS XT45 1080 mm Nova! 350 x 350 x 45mm pure cooling surface for nine 120mm fans. Just another Alphacool radiator offers more cooling surface in one piece: the Alphacool NexXxoS XT45 1260 SuperNova radiator.
As usual, Alphacool also relies on pure copper for the NexXxoS 1080 Nova radiator. The pre-chambers, the water channels and the cooling fins are made of copper and are a unique selling point worldwide. This makes the Alphacool radiators one of the most popular and best on the market for many years, which provides the perfect basis for any water cooling.
