Alphacool Eisbaer LT 240 Liquid Cooler Review

It’s now 2018 and the move towards all-in-one liquid coolers continues with nearly every cooler or watercooling manufacturer now offering a closed loop or open loop all-in-one liquid CPU cooler for purchase. Alphacool is no exception, now offering their second generation of Eisbaer liquid coolers. Well known as a custom watercooling supplier, they have begun to entrench themselves in the all-in-one market not only with their own offerings but as an OEM. As such, it’s not suprising that they continue to grow and refine their offerings to better suit the market.

Enter the Eisbaer LT 240, a standard 240 mm liquid CPU cooler with an integrated pump and CPU block that makes use of standard G 1/4” fittings. It also features quick-release fittings, which allows for easy expansion with Alphacool’s own GPX-Pro GPU-AIO units, much like the EKWB Pheonix line. However, this is a more affordable lower profile option as the Eisbaer LT series uses a slimmer 25 mm thick radiator. Before diving into what’s on offer, here are the unit’s specifications.

Alphacool has taken an already solid design and made it a bit more compact. The pump housing is much shorter than with previous designs, while the radiator is a bit thinner at just 25 mm. This makes the Eisbaer LT 240 one of the thinnest all-in-one liquid coolers on the market, which makes this newer offering a bit easier to install in smaller, cramped cases. Otherwise, clearance is also good on the Eisbaer LT as it does not interfere with graphics cards, and while it does block a DIMM slot when installed as indicated, the pump can be rotated to avoid the issue with no problems to report.

Compared to other liquid coolers, the Eisbaer LT 240 is expandable as it uses G1/4″ threaded fittings, which means users can in fact do some customization if they so choose. However, expansion is a bit limited by the pumps output of just 70 liters per hour. As such, expansion is most effective using Alphacool’s own GPX-Pro kits which feature a pump that works in tandem. This is made easier for consumers via the quick connectors that allow for plug and play functionality.

When it comes to performance, Alphacool can be proud. The Eisbaer LT 240 is smaller than typical all-in-one closed loop coolers while performing on par. This is in part due to its all copper design, which means consumers won’t have to worry about corrosion problems. Noise levels are also acceptable—not quite as good as the competition, they are close enough to be a non-issue.

A few issues are easy to spot. While the thinner design is good for smaller cases and cramped spaces, it means the Eisbaer LT 240 looses some surface area compared to the previous generation. That extra surface area it is missing, while minor, could have likely helped it move just ahead of the competition.

Fan quality is also a bit lacking. I noticed some rough spots on the fan blades during disassembly. When it comes to the fan blades themselves they were quite sharp, and I actually managed to cut myself on them. While not all the blades are that sharp, a few were. More importantly, this was not an issue with the previous generation of Eisbaer coolers—at least based on my experience.

The only other problems revolve around its short warranty of just two years since many closed loop liquid coolers now come with up to five years depending on the brand. Worse yet, availability stateside is non-existent unless you want to order one, in which case it would cost a great deal more than its estimated MSRP.

Overall, if you are looking for an expandable, affordable, high performance all-in-one liquid cooler, then take a good look at the Alphacool Eisbaer LT 240. Especially in the EU market does it prove to be of exceptional value compared to traditional closed loop offerings.
