Alphacool Eisbaer Pro Aurora: expandable water cooling

The solution from the German manufacturer is also perfect as a compact system, but due to its expandability it can also be the basis of a professional cooling.

Introduction, external

Anyone who buys water cooling today thinks almost exclusively of compact (or aka AiO, so all in one) systems. These “factory-assembled” solutions, the radiator, heat sink, pump and piping, come as a unit filled with liquid, so not only are they trouble-free to use, but installation into a PC is no more complicated than with a standard heat sink. The other, much smaller set consists of those who also assemble this cooling system by component, and they also carry out the assembly, filling and deaeration.


The first solution is more convenient, the second more professional: a water cooler built in this way offers more performance, and in addition to the CPU, you can also connect the graphics card, motherboard or even the power supply, who really puts time and energy into it, even as a PC decoration. you can do the cooling. For some time now, there have been products at the intersection of the two sets: compact water coolers that can be expanded as needed, so in theory they can offer the benefits of both philosophies – our test subjects are among them.



Alphacool is a major player in the market for “professional” water coolers and as such manufactures everything from pumps to blocks to radiators, as well as custom cooling solutions not only for PCs but also for servers and industrial environments. The company, which has been in existence since 2003, also has a whole range of extreme products, the Ice Age Chiller 2000 for example, a compressor with a cooling capacity of up to 1,500 watts TDP, so that temperatures below ambient temperature can be achieved.

Our test subject, the Eisbaer Pro Aurora, is a modular, compact water cooler: an assembly that can be used immediately out of the box, but if you want to expand it later with a GPU, or a second radiator or anything else, you can easily do it, thanks to for standard G1 / 4 threads, on the other hand, for a quick connector integrated in the pipe, which can be broken down without losing more than a few drops of liquid.



Examining the components of the system separately, the block is a professional unit using a nickel-plated copper base with an integrated pump and a bleed / expansion tank. Since we are talking about the Pro version of the Eisbaer family, the block size has been optimized for HEDT and server platforms – AMD TR4, IntelLGA3647 and others. His feet, as you can see in the pictures, got a mirror-smooth surface. As you would expect from a professional and multi-sized processor-compatible kit, the paste is not applied to the sole at the factory, but is obtained in a separate tube.


The expansion tank also has ARGB lighting (the name Aurora refers to this in addition to ARGB fans), which can be admired through small plexiglass windows on three sides, but the thin stripes at the top also illuminate. Here we find industrial, push-on pipe fittings that use a standard G1 / 4 thread, so if necessary, we can completely remove the block from the system. In the middle between the two connectors there is a section for filling the liquid supply, which can be opened with the help of a special screwdriver supplied with the system.


The tubes have been rubberized on the outside, there is no fabric cover or other decoration, their length including connectors is 40 cm. At the other end, on the radiator side, they end in the same way in industrial connectors. The radiator is also made of copper, making it surprisingly heavy and bulky; measuring 395 x 124 x 30 mm, this is where the company comes with three 120 mm air agitators Rise Aurora from the series.


These are PWM-controlled air vents with a maximum speed of 2600 rpm according to the website and 2500 rpm according to the fan sticker, officially with a noise level of 30-49.9 dB (A) – the latter already suggests that achieving this perfect silence is not its goal.


Finally, one of the add-ons is the small controller for the ARGB; although ideally the motherboard control takes care of the lights, if this is not available, we can also use this small unit so as not to be left without lighting.
