Details
The Alphacool NexXxoS XT45 Full Copper 200mm Radiator is a 200 mm radiator for 200 mm fans, 48 mm thick, with end chambers, water channels and cooling fins made of copper. The thicker radiator in the same fan size is the Monsta Full Copper 200mm radiator.

Make No Compromises, Use Copper
Alphacool opens with the question "Bigger is better... right!?" and answers it with pure copper, which it uses, as usual, for the NexXxoS 200 mm XT45 radiator too. Copper is what the end chambers, the water channels and the cooling fins are all made of, and Alphacool calls that 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. Alphacool sees them as providing the perfect foundation for every water cooling system.
Full cooling performance
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 at 400 W/(mK) for copper compared to 236 W/(mK) for aluminum and calls the winner clear. Alongside this is 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. The result, especially for such large radiators, is a fin spacing of 12 FPI. With that spacing the air flow is almost unobstructed. This means the air can pass through even without high pressure. However, Alphacool says, the cooling capacity does not suffer from this, on the contrary. To use the airflow optimally, all cooling fins have small serrations. 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?
The radiator offers space for 200 mm fans with 154 or 165 mm mounting holes on the mounting frame. The fans are screwed onto that frame, which can also be removed for purely passive operation in order not to obstruct the natural airflow. The thread size for fan mounting is M3.
Connection options
The radiator has five G1/4 threads in total: four for IN and OUT, and one on the back of the radiator that serves as a fill port. Alternatively, a temperature sensor or a drain port can also be attached here. Alphacool's closing line is "Small was yesterday". With a cooling surface of 20 x 20 cm, it says, the 200 mm XT radiator offers more than enough cooling power to cool every CPU and every graphics card.
What the loop needs
A loop uses two of the IN and OUT threads, so the radiator takes two G1/4 fittings, and the screw plugs in the box close the threads that stay unused. Four M3x30 screws and an Allen key are in the box as well.

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.
