2. 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. 

What our customers think

Pro

  • Good cooling capacity
  • Good workmanship
  • Good quality

Contra

  • Cooling fins very susceptible
  • Poor packaging

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.
 

6. Alphacool NexXxoS XT45 Full Copper 240mm

The NexXxoS XT45 Full Copper 240mm Radiator from Alphacool is a highly advanced solution for water cooling systems, designed for maximum cooling performance. With an impressive ability to dissipate up to 1400 W at an ambient temperature of 30 °C and a fan speed of 4000 rpm, this radiator sets new standards in heat dissipation.

The new Alphacool NexXxos radiator generation, a name synonymous with experience and quality, brings a breath of fresh air to the radiator market.

Every user of
water cooling needs a radiator, and everyone has different demands for the heat exchanger. Naturally, customers always want the best in its class. The Alphacool NexXxoS radiators have arrived to challenge the best in their class and to be the top radiator in all areas and sizes. No more back and forth; with Alphacool's NexXoS radiators, you know exactly what you have.

Alphacool has been a driving force in the development and improvement of radiators for years. 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 header tanks, are made of copper. This inherently leads to a performance boost where other radiators fall short.

The Alphacool NexXxoS X-Flow radiators differ significantly in design from conventional radiators. The X-Flow radiators are designed for high flow rates. The angled copper chambers on both sides are identically constructed. This allows water to flow simultaneously through all available channels to the other chamber, where it exits the radiator.
