With Eisbaer, Alphacool is fundamentally revolutionizing the AIO refrigerator market. Classic AIO CPU coolers are disposable products that are neither expandable nor rechargeable, Alphacool Eisbaer is modular and can be expanded, rebuilt or refilled at any time. This means that the Eisbaer is not just an AIO, but is based entirely on classic water-cooling components. That means it is quieter and more powerful than the average AIO solution.
