Top rated Water cooling radiators
Here's a ranking of the top rated products in this category. To give you a quick overview, we've also added some key information about the products.
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 ST30 Full Copper 560mm
The world-renowned manufacturer Alphacool is currently the only manufacturer in the world to use pure copper for all water-bearing parts. The pre-chambers, water channels and fins are all made of pure copper. As a result, Alphacool radiators offer the highest thermal conductivity, which means that the performance limit is significantly higher than with aluminium radiators. In short, the cooling capacity is simply higher if you want to dissipate a lot of heat. Copper has been the best choice of material in the water cooling sector for years.
All Alphacool radiators are designed for silent operation. This means that you do not need fans with particularly high static pressure to achieve the desired performance, but can rely on normal fans with low speed. The loss of performance compared to special fans for radiators is therefore minimal and can normally be ignored. Of course, those who want to achieve maximum cooling performance and rely on customised fans for radiators will not be disappointed. Maximum performance does not suffer as a result. Thanks to the copper and the high-quality manufacturing process, you still get an enormous increase in performance for your water-cooled components, even with high-performance fans.
The fans are mounted with the enclosed 30 or 35 mm M3 screws. All Alphacool radiators offer protection that prevents the screws from being screwed into the cooling fins. A metal plate underneath the holes prevents the screws from penetrating further. To mount the radiator directly on the housing, suitable screws are included in the scope of delivery.

4. Alphacool NexXxoS ST30 Full Copper 420mm
These models are among the first radiators that truly deserve the "Full Copper" designation. All main components, not just the fins and channels, but also the pre-chambers, are made of copper. This inherently provides a performance boost that other radiators cannot match. The internal structure is on par with radiators from other manufacturers, and separate pre-chambers clearly define the path of the coolant. A high flow rate enhances the cooling performance throughout the entire system. A flat end chamber also creates more space during installation, as the overall length is reduced. Space during installation is one of the key focuses of the development department at Alphacool. The pre-chamber has three options each at the inlet and outlet (not applicable to the NexXxos ST30) for positioning the connection. Fewer angles are required, which increases flow and offers more installation options. Therefore, this radiator can be installed even in tight cases where internal installation would otherwise not be possible.
5. Alphacool NexXxoS ST30 Full Copper 480mm
The NexXxoS ST30 Full Copper 480mm Radiator from Alphacool is a highly advanced solution for water cooling, characterized 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 NexXxoS ST30 offers significantly improved cooling performance, making it the ideal choice for high-performance systems. The radiator is designed for silent operation, meaning it can be used with standard fans without any noticeable drop in performance. This allows for quiet and effective cooling, while still providing the option to use high-performance fans to achieve maximum cooling efficiency. Installation is straightforward and secure, as the included screws ensure a hassle-free setup. The NexXxoS ST30 is thus an excellent choice for anyone seeking a reliable and powerful water cooling solution.

7. Alphacool NexXxoS ST30 Full Copper 240mm
The radiators are designed for both 120mm and 140mm fans. Various thicknesses of 30mm, 45mm, and 60mm highlight the wide range covered by these radiators. Additionally, the installation of the radiator as well as the fans and radiator covers is straightforward in this series: The M3 threads are standard in the radiator sector and are available at a low cost in all lengths. Even the dreaded over-tightening of the mounting screws does not lead to costly damage with this radiator, as an internal protective edge stops the screw from penetrating before it touches the fins. The spacing of the fins has been chosen so that the radiator achieves optimal cooling performance even with slow and medium-speed fans. This is not only pleasant in terms of noise levels but also does not limit the choice of fans.
