Alphacool Eisbaer 240mm AIO Liquid CPU Cooler Review


Introduction to the Alphacool Eisbaer AIO Liquid CPU Cooler

Eisbaer? What!? Try pronouncing it like Ice Bear and itll make a whole lot more sense! It could be written as Eisbr, to confuse native English speakers more, but thankfully it is not. It translates to Polar Bear in German, which Germany is exactly where Alphacool is stationed. First shown off at Computex 2016, today Alphacool is taking the wraps off of the Eisbaer AIO Liquid CPU Cooler and we have one for review! Alphacool has worked with various partners in the past, such as Fractal Design, ASUS, Sapphire, and even Cooler Master, designing cooling solutions for their various needs; theyre actually quite the one-stop-shop for water cooling products for everyone. This is a pretty neat looking cooler, so lets hope the performance is as good as the looks.

Alphacool has a vast array of cooling parts, allowing you to build your own custom cooling loops. The Eisbaer is an all-in-one, but it kept the possibility of the end user wanting more out of their cooler in mind. One thing that youll likely immediately notice on this cooler is the fact that it has quick connects. These connectors use G threads, so you will have no shortage of parts available to you. In fact, Alphacool says that the Eisbaer will have no problem handling two 240mm radiators and a graphics card cooler in the loop. This cooler will absolutely be compatible with their upcoming GPX-Pro GPU cooler, which will be released later this year.

You will find the Eisbaer available in 120x45mm, 240x30mm, 280x30mm, and 360x30mm radiator sizes, which the technical foundation for these radiators is Alphacools NexXxoS ST30 radiators. The only difference between this radiator and the NexXxoS is a missing connector on the head and opposite side.
