Full copper
Alphacool presents the new NexXxos radiators under a name that, in its words, stands for experience and quality and has come to bring a fresh breeze to the radiator market. Its reasoning is that every user of a water cooling system needs a radiator, and that everyone has different requirements toward the heat exchanger. Of course, Alphacool writes, the customer always demands the best in its class. By its own account these radiators have come to compete with and to beat the best in their class, and to be the best radiator in all sizes. Alphacool promises no more endless choices without a clear class leader and calls the NexXxos the one tool for all your cooling needs.
Alphacool describes itself as the company that has been the one to introduce new developments and improvements in the radiator and water cooling sector generally, many times over the last years. Following this tradition, it says, the new radiators are the first to truly deserve the "Full copper" attribute. Every one of the main parts is made from copper: not only the fins and channels, but also the chambers. In Alphacool's view this brings an improvement in performance where other radiators are left without a chance. It adds that the material already gives an advantage over the competition and that the inner structure is up to par with it. Separated chambers give the coolant a clear direction, allowing the high flow rates which Alphacool says improve the performance of the whole cooling loop. The chambers on the heat exchanger are flat, and thanks to the reduced overall length they increase mounting flexibility.
Mounting
Versatile and easy mounting is one of the main points on which the research and development department at Alphacool focused. On both the inlet and the outlet, the chamber offers three possibilities for fitting installation (not on the NexXxoS ST30). Less angled fittings are needed that way, improving flow rates and offering more mounting possibilities. Hence the radiator can even be installed in tight enclosures, where internal installation is otherwise not a possibility. On all UT60 and NexXxos Monsta radiators a G1/4 screw plug allows easy de-aeration of the radiator and hassle-free vertical installation of the heat exchanger. That threaded opening can even be used for filling, e.g. in combination with a Fillport.
What the loop needs
Alphacool's technical data lists 6x G1/4 connections. A loop uses two of them, so the radiator takes two fittings, and the other four are closed with screw plugs, of which the box holds five. Two 140 mm fans fit the radiator, and the box has eight M3x30mm and eight M3x35mm hexagon socket screws for the M3 fan thread.
Alphacool calls versatility the essence of the new NexXxos series. The radiators are available in different versions, to be used with 120mm, 140mm or 180mm fans, and in different thicknesses. In its words the choice of 30mm, 45mm and 60mm offers "the perfect radiator for every purpose". Alphacool also describes mounting and installation of fans and radiator grills as easy and versatile with these radiators. The M3 threads are standard in the radiator sector, and screws for them are available in all lengths at an affordable price. Even the dreaded insertion of a screw too far into the radiator does not result in expensive damage, according to Alphacool. Unlike other radiators, it says, the NexXxos series is equipped with an internal protective ledge which stops the screw before it damages the fins.
Fins and fans
Alphacool calls fin spacing always an important factor in radiator design. By its account the new series from Alphacool has a fin design which allows it to perform extremely well even with slow-spinning and medium-speed fans. Alphacool finds that not only pleasant, thanks to the fact that it avoids unnecessary noise. It also means, the company adds, that the choice of fans that can be used with these radiators is not restricted. Alphacool sums the radiators up as the result of experience and powerful performance meeting future-oriented design and well-thought through solutions.

Notes
- Use only clear, transparent water cooling fluids. Alphacool warns that the particles and additives in pastel liquids can clog and permanently damage water cooling products such as radiators, pumps, coolers and hoses. It adds that this can result in voiding the manufacturer's warranty as well.
