Cooler Master Eisberg 240L Prestige Liquid CPU Cooler Review

At stock we saw only a marginal improvement over the smaller Eisberg 120L. The Eisberg 240L also is a fair bit behind the 280mm AIOs but retains competitive distance to the Swiftech H220 and Corsair H100i.


The acoustics were marginally louder than the Eisberg 120L Prestige as the two fans were pushing and pushing fans tend to be a bit louder.


Overclocking saw competent results. I am actually slightly worried and how little difference there was between the Eisberg 120L at 5 volts although the gap did grow as we tested the Eisberg 240L at 7 and 12 volts. Still I was slightly underwhelmed by the performance of the unit. Given how large and powerful the pump is, I expected more. I opted for some Noctua NF-F12s to see if the fans were holding the Eisberg 240L back, and not surprisingly they were but not by that much – only about 1 degree.

The difference between the Swiftech H220 and Eisberg 240L is about 1 degree at equivalent volt levels. I think the reason why the Swiftech H220 wins is just purely because it has better quality fans, not to mention the fact they are PWM and a lot quieter too. The 280mm Asetek based Corsair H110 and NZXT Kraken X60 are both worth honourable mentions here. Both units performed better and clearly the extra surface area does make a difference. Also the Corsair H100i has held its ground well too, no doubt thanks to the excellent quality of the SP120 fans Corsair use.


Acoustics were pretty load above 7 volts and this is mainly due to the pump getting hugely noisy at higher RPMs. Though swapping the fans out did make a difference and the Noctua NF-F12s produced less noise and better temperatures compared to the stock Cooler Master fans.

    Horrible opinion and review. It may be different and new, but I would like to know who would actually use this and who would it be the BEST solution for? No one. And for a product to be good, there has to be a perfect consumer for it. It’s louder than air cooler (which defeats the one of two reasons for water cooling imo). Not the great performer/acoustic ratio. Expensive. I like eteknix and I’m a coolermaster fan (pun not intended), but I do not agree that this product deserves any type of award. Also, as coolermaster does things like this, it makes me feel that they are a one trick pony that got lucky and stumbled into the main stage with their hyper 212+ (in which I have to say they never really greatly improved on). They keep coming out with products that have higher margins, but they never come out with something really innovative. They add a bunch of plastic to make their coolers look more cool but their claim to fame is bang for buck. Other companies that make higher margin products (Corsair) actually deliver. I feel like Coolermaster is just a company that has 1-dimensional thinking engineers and ancient managers/leaders that are disconnected from the consumer demands/wants/needs. I think they look up to Apple and think, oh, let’s just make things sleek and people will buy it. Nope. If anything, this is a very crude rough draft of something that might be good.

    I had a look at this cooler and played around with it for a couple of hours last week and although I couldn’t conduct an in depth test due to the fact It wasn’t installed on a test bench in a climate controlled room and had no sound measuring equipment I have to say that I echo your sentiments entirely Ryan.
    I wasn’t impressed by the included fans at all and when I swapped them for Corsair 2 X SP120’s I noticed a drop in temperatures. Again I want to stress that I never conducted any in depth or meaningful tests due to the reason stated above. (I’ll leave the proper testing & findings to our youngsters, I’m taking a backseat nowadays)
    I was impressed with the presentation & build quality of the unit but certainly not the price.
    If Cooler Master addressed the latter and it’s bundled fans the cooler would certainly be a product to be reckoned with.
    I’ll leave it at that.

    Eisberg is just more then a normal AIO and is something for Professionals — Haters like compare it the wrong way.

    Open Loop Cooling like Swiftech and Cooler Master Eisberg – make it possible to cool down CPU and GPU at once. Corsair and Nxzt System will never do that. Closed loop system are so limited. I will go for open loop Systems and hope the Industry will create more of the open loops systems. Closed loop copied of asetek is already so boring…
