Would you like a little more?

That is the question Alphacool opens with, and its answer is 35 x 35 cm of pure cooling surface. Only one other Alphacool radiator offers more cooling surface in one unit: the NexXxoS XT45 1260 SuperNova. Alphacool's summary: "It's a big boy!" Only one other radiator in its portfolio, it says, can match the performance of this one. With nine fans and a pure cooling surface of 35 x 35 cm, it adds, the Nova name says it all.

Make No Compromises, Use Copper

As usual, Alphacool also uses pure copper for this radiator. The end chambers, the water channels and the cooling fins are all made of copper, which Alphacool calls a unique selling point worldwide. As a result, it says, its radiators have been among the most popular and best on the market for many years. It sees them as providing "the perfect foundation for every water cooling system".

Full Cooling Capacity

To maximize the performance of a radiator, Alphacool says it reaches deep into its bag of tricks, with copper as the starting point. It puts the thermal conductivity of copper at 400 W/(mK) compared to 236 W/(mK) for aluminum and calls the winner clear. Alongside this is what it calls the special fin density. Alphacool describes itself as one of the oldest companies in the field of water cooling and says it has carried out countless laboratory tests. For such large radiators especially, the result is a fin spacing of 12 FPI. The air flow is then almost unobstructed, which means the air can pass through even without high pressure. However, Alphacool says, the cooling capacity does not suffer from this, on the contrary. All cooling fins have small serrations to use the airflow optimally. These are tiny flaps that guide the airflow in the desired direction and increase the surface area. In the case of radiators they are barely 1 mm high, but Alphacool says they still provide controlled air turbulence to increase cooling capacity and minimize airflow noise.

Which fans?

On the detachable mounting frame the radiator has space for nine 120 mm fans, mounted with M3 threads. If you want to operate the radiator passively, you can remove the mounting plate in order not to obstruct the natural airflow. Of course, Alphacool adds, the mounting plates for both types of fans can also be interchanged, which gives you more freedom when mounting the fans.

Connection options

The radiator offers two G1/4 threads for IN and OUT. A further G1/4 thread sits on the back of the radiator and serves as a fill port. Alternatively, Alphacool notes, a temperature sensor or a drain port can also be attached here.

What the loop needs

Of the three threads a loop uses two, so the radiator takes two G1/4 fittings. The third takes the screw plug in the box when it is not in use as a fill port. For the nine 120 mm fans the box has 36 M3x30 screws, with an Allen key. Its certificates are CE, FC and RoHS.

Technical data

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 void the manufacturer's warranty as well.
