Alphacool Eisbaer 420 AIO 420mm CPU Watercooling Kit - Black [11390]

The individual components

Radiator
Alphacool uses a radiator made of pure copper. The basis of the radiator is the popular Alphacool NexXxos series, which is globally renowned. The pure copper design increases the cooling performance enormously compared to the usual aluminium radiators found in classic AIOs. The thin fin thickness ensures impressive cooling performance with fans that have low RPMs. The Eisbaer’s performance also drops much slower when the fan power is lowered than radiators with higher fin thickness.

Tubing
Flexible PVC tubes make installing the Eisbaer easy. The tubing is easy to lay and get into the right position. Both tubes have anti-kink springs to prevent them from bending and cutting off the flow of water. Their 11/8mm size is also a standard in the water cooling field, and is a common size alongside the 13/10 and 16/10.

Quick Connectors
The Eisbaer was developed with expandability in mind. That’s why you’ll find a quick connector on one of the tubes. This quick connector is compatible with Alphacool HF Quick Connectors, making it easy to expand the cooling loop with a radiator and graphics card cooler.

Fans
The Eiswind fans were specially designed for use in radiators and provide very high static pressure to force cool air through the radiator’s cooling fins. Both fans can be regulated via PWM over an enormous range of 550 to 1700 RPM. A PWM Y-adapter is included with the Eisbaer, so both fans can be connected to a PWM connection on your motherboard or a separate fan controller.

Connectors
All connectors are based on the classic G1/4 inch threads, which are standard in the water cooling field. That means all the components can be switched out at any time if desired. So if you decide later that you’d rather have thicker tubing or even HardTubes, you can easily customise your system.

All these features make the Eisbaer cooler something really unique. Its high-quality aesthetic with an illuminated logo and reservoir – which is also where the pump is found – gives the inside of any PC a new shine. The soft-touch surface of the pump casing is another optical highlight.
With the Eisbaer, you get an all-around perfect product that is not only extremely powerful but can also run near-silently.

Pump
The basis of the pump is the Alphacool DC-LT Ceramic Ultra Low Noise pump, which is also available separately. The pump runs extremely quietly and can be regulated between 7 to 12V. You can also control the pump via your motherboard. If the Eisbaer is running on its own, running the pump at 7V won’t lower performance at all, as proven in many tests. The insulated pump casing reduces the noise generated and also almost entirely absorbs vibrations.
The smooth and glossy polished copper bottom of the cooler ensures optimal heat absorption and quickly and efficiently transfers heat to the water via the fine cross slot structure of the cooler.
