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 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. 

3. Alphacool NexXxoS XT45 Full Copper 360mm

The Alphacool NexXxoS XT45 Full Copper 360mm Radiator is a highly advanced solution for water cooling systems, tailored to meet the needs of demanding users. With a focus on performance and efficiency, this radiator offers outstanding cooling performance, supported by the use of high-quality copper in all main components, including the inlet chambers. This design ensures high flow rates and improved heat dissipation, making it an ideal choice for high-performance systems. The radiator is designed for easy installation, while the flat end chamber provides additional space. The combination of thoughtful design and premium materials makes the NexXxoS XT45 one of the best radiators on the market.

- Fully made of copper, including the inlet chambers, for optimal heat dissipation
- High flow rates through separate inlet chambers, enhancing cooling performance throughout the system
- Flat end chamber design for more installation flexibility and reduced overall length
- Pressure tested up to 2 Bar to ensure reliability and durability.
 

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 XT45 Full Copper 280mm

All Alphacool radiators are designed for silent operation. This means 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 either. The maximum performance is not compromised. Thanks to the copper and the high-quality manufacturing process, you will still experience a significant performance boost for your water-cooled components, even with high-performance fans. 

6. MagiCool G2 Slim Radiator 16 FPI

The Chinese manufacturer Magicool offers solid water cooling technology with an excellent price-performance ratio. This is also true for the 360mm triple radiator from the G2 series presented here. The heat exchangers of the G2 series are particularly characterized by their flat design with a height of only 27 mm and their "Dual Pass" design with two parallel water paths. Additionally, the G2 radiators have a fin density of only 16 FPI, allowing even low-speed silent fans to generate enough pressure to penetrate the copper fins. Fans can be mounted on one or both sides of the triple radiator. Thanks to the low height of just 2.7 cm (without fans) and a width of 12 cm, which does not exceed the expansion of a fan, the G2 models are highly compatible with many cases and feature two standard G1/4-inch connections for integration into a cooling loop. 

7. Thermaltake Pacific CL480

The Pacific CL480 is a radiator for water cooling systems with five connections for G1/4". Built into the water cooling circuit, the Pacific CL480 cools the coolant down again. The Pacific CL480 Radiator with high density copper fin design and brass tank. Built for 120mm fans, the radiator is made of high quality materials that provide exceptional performance and reliability. Integrated G1/4" threads allow easy installation.

9. 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. 

10. Corsair Hydro X Series XR7 360mm
