2. Alphacool NexXxoS 480mm
All Alphacool radiators are designed for silent operation. This means that they do not require fans with particularly high static pressure to achieve the desired performance; instead, you can use standard low-speed fans. The performance loss compared to specialized radiator fans is minimal and can usually be ignored. However, those who want to achieve maximum cooling performance and opt for tailored radiator fans will not be disappointed. The maximum performance is not compromised. Thanks to the copper and the high-quality manufacturing process, you will still see a significant performance boost for your water-cooled components, even with high-performance fans. The fans are mounted using the included 30 or 35 mm M3 screws. Additionally, all Alphacool radiators feature a protection that prevents the screws from being driven into the cooling fins. A metal plate beneath the holes prevents further penetration of the screws.

3. Alphacool NexXxoS UT60 Full Copper 360mm Special Edition
The NexXxoS UT60 Full Copper 360mm Radiator from Alphacool is a highly advanced solution for water cooling, distinguished by its complete construction from pure copper. This material ensures superior thermal conductivity, allowing for efficient heat dissipation at high temperatures. Compared to conventional aluminum radiators, the UT60 offers significantly improved cooling performance, making it the ideal choice for high-performance systems that require intense cooling. The radiator is designed for silent operation, meaning it achieves excellent performance even with standard low-speed fans. This minimizes noise levels without compromising cooling efficiency. The fans can be easily and securely mounted using the included M3 screws, while a special protection mechanism prevents the screws from penetrating the cooling fins. Weighing 1756 grams and featuring a robust design, the radiator is both powerful and durable.
- Completely made of pure copper for optimal thermal conductivity
- Silent operation allows the use of standard fans
- Easy fan installation with M3 screws
- Protection mechanism against screw penetration into the cooling fins
- Pressure tested up to 1.5 Bar for increased safety.

4. Alphacool NexXxoS XT45 Full Copper 480mm
These models are among the first radiators that have really earned the title "Full Copper". All main elements, not only the fins and channels, but also the antechambers are made of copper. This already brings an increase in performance due to the material, where other radiators fall by the wayside. The internal design is at eye level with radiators from other manufacturers and separate antechambers clearly define the path of the coolant. A high flow rate increases the cooling capacity in the complete system. A flat end chamber also leaves more space during assembly, as the overall length is thus shorter. Freedom during assembly is one of the central points on which the development department at Alphacool has concentrated. At the inlet and outlet of the antechamber there are 3 possibilities each (not with the NexXxos ST30) to position the connection. Fewer angles are required, which in turn increases the flow rate and provides more mounting options. Therefore, this radiator can be installed even in tight enclosures where an internal installation would otherwise not be possible.

8. Alphacool NexXxoS 280mm
The new NexXxoS Monsta series from Alphacool is truly unique. This new generation of radiators offers a significantly larger cooling surface with a thickness of over 80 mm compared to previous models, resulting in a noticeable improvement in cooling performance. The series ranks among the best radiators in all areas and sizes. Its simple black design makes it visually compatible with any system.
The NexXxoS Monsta radiator is made from copper. It is rightly called a "Full Copper" radiator, as not only the fins and channels are made of copper, but also the inlet chambers. Each inlet chamber features three inlets and outlets, allowing for flexible connections to custom water cooling systems. This reduces the need for bends, enhancing flow and thus improving cooling performance. In addition to the six connections, there is a seventh G1/4" thread, which serves for venting but can also be used for filling.
This massive radiator, which boasts a thickness of 86 mm and a length of 324 mm, has an incredibly large cooling surface. The fin spacing has been optimized to achieve effective cooling even with slow fans. However, the higher the fan speed, the better the cooling performance compared to thinner competitors. For instance, the cooling performance with a fan running at 1200 RPM is roughly equivalent to that of a 60 mm radiator with two fans.
Technical details:
- Dimensions: 324 x 86 x 144 mm (W x H x D)
- Material: Copper, Brass, Steel
- Color: Black
- Weight: 2.02 kg
