Conclusion

Arctic Cooling designed the Liquid Freezer II series of all-in-one coolers for users who value subtle designs and seek a good price-to-performance ratio. The series currently consists of five coolers, ranging from a small single 120 mm version to the massive three 140 mm fans version that we reviewed today. All share the same main block and tubing, making the choice of radiator more of a compatibility matter than anything else.

Although they look very simple at first glance, the Liquid Freezer II coolers actually are niftily designed. They combine quality and elegance in an ingenious way rather than relying on colorful lighting to draw attention. The designer’s idea to incorporate the wiring of the fans into the cooler has several advantages, including quicker installation and a very clean appearance once installed. Our only worry lies with using the triple-fan models with low-end motherboards, as it's possible that the power circuitry of the motherboard may be overloaded by the entirety of the cooler’s power needs. Then again, there probably aren't too many builders and PC enthusiasts installing such a massive liquid cooler on a low-end motherboard to begin with.

In terms of performance, the Liquid Freezer II produces very good results. Their thermal performance seems to be excellent, with the cooler that we have tested outperforming similarly-sized competitors. Most of that advantage comes from the radiators, which do offer better heat exchange rates but, on the other hand, their thickness absolutely needs to be taken into account when determining if the cooler is compatible with a given case/system. Meanwhile, the acoustics performance of the Liquid Freezer II coolers is somewhat worse compared to that of similar offerings, with the small 40 mm fan on the main block being mostly to blame for these results. Nevertheless, the coolers are not actually loud or intrusive and most users would probably welcome the additional cooling for the motherboard’s vital power components.

Arctic Cooling is a company that typically designs practical, ‘no-frills’ products, aiming to perform reliably and retail at a reasonable cost. The Liquid Freezer II AIO coolers are no exception, as they are sporting a subtle design and offer excellent overall performance at a very reasonable price tag: the 240 model sells for just under $100, and even the mammoth 420 model is only $160 – at least if you can find it in stock.

Ultimately, If you are seeking to purchase a high-performance cooler and do not care about RGB lighting or other aesthetic features, the Liquid Freezer II coolers are equally capable products that retail at a significantly lower retail price than most of the competition and should definitely be on your shortlist for consideration.

    Is this compatible with TRx40 AMD cpu's? Reply

    On the first page:

    "It is large enough for most commercial processors but will not cover a ThreadRipper processor, for which the Freezer II coolers have no stock support for out of the box."

    I was looking for 360mm because it was $120 for amazon a week or 2 ago but now they are sold out. But yesterday 420mm was available off amazon for $160 so I grabbed that. Hopefully it'll fit into my Phanteks Pro. Replacing Deepcool Captain 360 from 2017. Kinda an overkill for a 5600x. With Deepcool I'm getting 73C and lots of throttling 5600x @ 4.85Ghz (kryonaut thermal paste). Reply

    Yeah the 360's are hard to find. I got lucky and picked one off of Amazon at MSRP a few weeks back. Reply

    In reality all of the Liquid Freezer IIs are hard to find. When you do find them, typically they are selling for over MSRP. Reply

    I couldn't find the 420 version in Germany, the 360 was available however. Might just upgrade later. Reply

    lol kinda overkill a 420mm on a 6 core 5600x 65watt tdp chip indeed. Reply

    Update: the 420 cooler came in. It took me over an hour to put in. It almost didn't fit. CPU power was in the way, I had to force it a few millimeters out of the way. I ran 3D mark time spy like I did with 360 Captain and I got 70C vs 73C. Mobo fan curve is set to Performance. It does improve cooling and it takes longer to heat up but it does heat up. I did a stress test with cpu z for a few minutes and it did heat up to 72C. I am OCing 5600x to 4850 with PBO 2. Undervolt curve on 4 cores at - 15 and 2 best cores at - 5. I'm kind of disappointed that the best cooler I can get only delays the heat and not keep the the CPU under 70C. Maybe if I manually OC it will have lower temps. Maybe I didn't put enough kryonut thermal paste. I'll try to re-do it later. I will try to replace the fans with NH U12A 3000rpm fans later. Reply

    I was able to get the 360mm for €90. I replaced the NH-U12A which was the same price. Now I get about 20°C less at also lower noise... 3900X CPU. Reply

    Surprising that it has become a thickness race already. You still get to claim top performance at x dimensions with a caveat (that it won't fit lol). Thinner fans could help, but that will cost more, and be louder. Reply
