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 individual components
Alphacool depends on a radiator made of pure copper. The base of the radiator is the popular Alphacool NexXxoS series, which is well-loved around the world. The pure copper construction raises the cooling performance enormously compared to the usual aluminium radiators used in classic AIOs. 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 flexible PVC hoses make installing the “Eisbaer” easy. These hoses are easier to arrange and move into the right position. So the hoses don’t bend and stop the flow of the water, both hoses have been fitted with anti-kink springs. The 11/8 mm size is also a standard in the water cooling field, alongside the 13/10 and 16/10.
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 (1010383, 1010394, 1010395, 1010442), with which the circuit can easily be expanded to include anything from a radiator to a graphics card cooler. Furthermore, the “Eisbaer” is compatible with the upcoming Alphacool GPX-Pro graphics card AIO, which will use identical quick-lock closures.
In cooperation with bequiet! The Eisbaer uses the Pure Wings 2 fans to push cool air between the cooling fins. Both fans are operated via a 3-pin connector. A Y-adapter is included in the Eisbaer, so both fans can be controlled via a port on their motherboard or a separate fan control.
All connectors are based on the classic G1/4 inch thread, the standard thread in the water cooling field. This way, all attachments can be switched out for others any time as desired. This also means that, for example, you could later decide to switch to thicker hoses or even HardTubes and set your system uniquely apart.
All these features make the “Eisbaer” cooler into something extraordinary. Its enhanced appearance from the illuminated logo and the illuminated reservoir, which also contains the pump, lets the interior of your PC shine in a whole new way. The soft-touch surface of the pump case is a further visual highlight.
With the “Eisbaer”, you get an all-around perfect product that is not only extremely high-powered but also works very quietly.
The basis of the pumps is the Alphacool DC-LT Ceramic Ultra Low Noise, also available separately. The pump runs extremely quietly and can be regulated to between 7 and 12V. It can also be regulated through the motherboard. If the “Eisbaer” is being run alone, the 7V setting will still have next to no performance loss, as shown in diverse test results. The insulated pump case further perfects the noise generation and ensures that vibrations are almost completely absorbed.
The smooth and shiny polished copper base of the cooler ensures optimal heat absorption and can relay the heat over the fine slit structure of the cooler to the water quickly and efficiently.

We would also like to advise that Mayhems fluids can damage water cooling products, and using Mayhems fluids can thereby void the warranties offered by the following manufacturers: Koolance, Phobya, Alphacool, Aqua Computer, Watercool.
Damages such as: clogging, corrosion of aluminium radiators, deterioration of glued containers, etc., are a consequence of the use of Mayhems, but will not be reimbursed by Mayhems. Use is therefore at one’s own risk.
Please take care not to mix up the IN and OUT ports. On the “Eisbaer”, the “outlet” is marked in “red” and the “inlet” in “blue”. On the components to be connected, it is the opposite. The coupling with the “blue” marking denotes the “outlet” and the coupling with the “red” marking is the “inlet”. This is important as in many coolers the flow direction is crucial for optimal cooling performance.

Really awesome product, I'm using it for CPU Ryzen 2700X with GPU extension Alphacool NexXxoS GPX for RX 480 and everything is cool and quiet.
CPU is running:
- normal workload (windows 10) is bellow 40C
- normal load (games) is between 45-50C
- maximum load (Cinebench 15) is aroudn 62C and witout any throttling
GPU is running:
- normal workload (windows 10) is bellow 34C
- maximum load (games) is between 48-55C and witout any throttling (GPU OC is 1390MHz)
The Alphacool Eisbaer serves well all my needs
Easy to install, easy to maintain, silent, durable, high value and expandable.
Thank you Alphacool
Kann ich uneingeschränkt weiterempfehlen. Muss man nur aufpassen das der Kupferradiator auch in das Gehäuse passt.
Best of this product is the quick coupling connector. Never have seen anything like that.
So although I did not expand the system yet, this is definately something worth thinking about.....
Die Eisbär ist einfach nur klasse. Ich bin sehr zufrieden. Kein Wunder, Alphacool setzt schon seit Jahren erfolgreich auf Radiatoren aus Kupfer. Spitzenprodukte mit Spitzenkühlleistung sind nur so gewährleistet (siehe Wärmeleitfähigkeit —> http://www.chemie.de/lexikon/Wärmeleitfähigkeit.html). Andere Hersteller mit billigen Aluminium-Radiatoren und sogar CPU-Kühlern aus Aluminium sind nur halb so gut.
Die Verpackung bei Alphacool wie auch die Anleitung zum Einbau ist sehr gut und zu schade zum Wegwerfen.
Die Eisbär 280 CPU wurde schnell geliefert. Es war reibungslos. Scheint wirklich gut zu laufen das Produkt. Kein Wunder.
First of all thank you Aquatuning for the great service. The package arrived in time and it was packed really well. For the product, the installation was fairly easy and I am amazed by the great performance! After installing and a 4 hour gaming session the temperature was at incredible 45 degrees! For comparison, with my old air cooling system it got up to 65 degrees. Now that’s an improvement! In conclusion I would easily recommend this product to anyone who’s looking for a new cooling device for his/her PC.
