With the “Eisbaer”, Alphacool is fundamentally revolutionizing the AIO cooler market. Where traditional AIO CPU-coolers are disposable products which are neither upgradeable nor refillable, the Alphacool “Eisbaer” is modularly built and can be upgraded, rebuilt or refilled at any time. This means that the “Eisbaer” is not only an AIO, but also fully built on classic water cooling components. That means it is quieter and more powerful than the average AIO solution. The base of the radiator is the popular Alphacool NexXxoS series, which is well-loved around the world. The slight thickness of the fins ensures enormous cooling power in fans with low rotational speed. This ensures that the performance of the “Eisbaer” when adjusting the fans down decreases much more slowly than in radiators with higher fin thickness. The “Eisbaer” was designed with expandability directly in mind. This is why you’ll find a quick-lock closure on one of the hoses. This quick-lock mechanism is compatible with Alphacool HF quick-lock closures, with which the circuit can easily be expanded to include anything from a radiator to a graphics card cooler. The “Eiswind” fans were developed specially for radiators and generate a high static pressure in order to push cool air through the fan blades. Both fans can be regulated with PWM to anywhere in an enormous range from 550 to 1700 RPM. A PWM Y-adapter is included with the “Eisbaer” so that both fans can be controlled by the motherboard or a separate fan control with a PWM connection. All connectors are based on the classic G1/4 inch thread, the standard thread in the water cooling field. The basis of the pumps is the Alphacool DC-LT Ceramic Ultra Low Noise. The pump runs extremely quietly and can be regulated to between 7 and 12V. It can also be regulated through the motherboard. The insulated pump case further perfects the noise generation and ensures that vibrations are almost completely absorbed.
