Best selling Water cooling radiators

Here's a ranking of the best products in this category. To give you a quick overview, we've also added some key information about the products.

1. Hailea Ultra Titan 500 HC300

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.

Which aquarium size does my continuous flow cooler cool?
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).

6. 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.
