Best selling Water cooling radiators from Alphacool

On this page you’ll find a ranking of the best Water cooling radiators from Alphacool. To give you a quick overview, we’ve added the most important product details. This page always stays fresh and updates automatically.

1. Alphacool NexXxoS ST30 Full Copper 360mm

Free space during assembly is one of the central points on which the development department of the Alphacool NexXxos ST30 360mm has concentrated. 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. The flat end chamber of the NexXxos ST30 360mm also allows more space during installation, as the overall length is thus smaller. 

2. Alphacool NexXxoS ST25 Full Copper 120mm Radiator

The NexXxoS ST25 Full Copper 120mm Radiator from Alphacool is a highly advanced solution for water cooling, designed for both industrial applications and home use. With a clear focus on performance and quality, Alphacool uses pure copper for all critical components, including the manifolds, water channels, and cooling fins. This choice of material not only ensures superior thermal conductivity but also enhances cooling performance compared to conventional aluminum radiators. The radiator features a special design that optimizes airflow while minimizing pressure loss. This allows for efficient cooling even at low air pressure. The NexXxoS ST25 is therefore an ideal choice for anyone seeking a powerful and reliable water cooling solution.

- Pure copper for all cooling components, ensuring superior thermal conductivity
- Optimized fin spacing of 15 FPI for minimal air resistance and maximum cooling performance

5. 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
- Connections: 6x G1/4 inch
- Fan compatibility: 2x 140 mm
- Fan/radiator mounting: 8x M3x30mm, 8x M3x35mm.
