The cooler is designed for 140mm high-pressure fans and is made from high-quality materials that provide exceptional performance and unmatched reliability. The unique stainless steel side panels ensure durability while reducing the weight of the cooler. Integrated G1/4" threads facilitate installation, while rigid connections ensure leak-proof measures are in place. With ideal mounting, assembly, and flow adjustment, the Pacific CL420 cooler meets your cooling needs in every way.

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.

The EK Quan Surface P360 bk Edition is a powerful 360mm radiator specifically designed for water cooling systems.

The radiator features five G1/4 ports, including one for venting, and is easy to disassemble, making it particularly suitable for modding. The high-quality craftsmanship and durable coating ensure longevity and low noise levels, while the high water flow is guaranteed by the sixteen 2mm copper tubes inside. This radiator is ideal for custom loops and provides optimal cooling performance with reduced air resistance.
- 360mm copper radiator for optimal heat dissipation

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
- Pressure tested up to 0.8 Bar for increased safety and reliability
- Compatible with common water cooling systems through standardized G1/4 connections.

This continuous flow cooler essentially replaces the radiator, as the water is regulated down to a temperature set by you. Temperatures of up to 4°C are possible, but please note that condensation can form due to the temperature difference. The temperature can be set in single steps up to 28° C via the display. Appropriate insulation accessories (for hose and CPU) are also available. Alternatively, the chiller can be set to a value just below room temperature to avoid the problem of condensation.
Due to the low water temperatures, unimagined possibilities for overclocking are given. The service life of your components is increased many times over. Furthermore this system is also interesting for No Noise applications, because the chiller can be placed in another room. We recommend integrating the chiller as an additional cold source in a system next to an existing radiator. So you can switch off the normal radiator as needed (overclock / benchmark / midsummer etc) and the chiller will take over the cooling.

The manufacturer's information is as follows:
Model / litre specification:
HC-130 / 50-100L
HC-150 / 50-200L
HC-250 / 100-300L
HC-300 / 100-400L
HC-500 / 200-800L
HC-1000 / 300-1000L
HC-2000 / 400-1500L
Here we would like to point out that the manufacturer's specifications were created under optimal conditions. For example, the temperature behaviour can vary considerably due to the insulation of the pool, the radiation of the lamps or the sunlight. Therefore we recommend to choose a larger model when reaching the upper limit of the litre values.
Note on compatibility: The chiller is supplied with connections for 1 inch hose (inner diameter approx. 19 to 20mm). The delivery includes 1 pair of straight and 1 pair of 90° angled connectors. To use the Chiller with standard connections we recommend art. 37018 (for G1/4) and 37019 (for G3/8).
