The Arctic Liquid Freezer II is giving me chills
You’re probably familiar with Arctic as the maker of great thermal compounds used the world over a decade. You might not know, however, that they make an array of coolers for CPUs and GPUs. I admit, I wasn’t aware of this until I was asked to take a look at the Arctic Liquid Freezer II. I’ve used a handful of AIOs over the years, but find that I generally fall back to a good air cooler.
Setting up to test the Arctic Liquid Freezer II
|MB||ASUS Crosshair VI Hero|
|CPU||AMD Ryzen 1800x|
|Ram||32GB Balistix Elite (3200MHz)|
|SSD||512GB ADATA SX7000|
|GPU||Gigabyte Radeon Vega 56|
|Case||Fractal Design Meshify C|
|Fans||BeQuiet Silent Wing 3, 3x 140mm intake, 1x 120mm exhaust|
I tested a Ryzen7 1800x. This is an 8 core 16 thread CPU with a 95w TDP based on AMD’s first generation Zen architecture on stock clocks. The testing environment was well controlled, with an ambient temperature of 23.33° Celsius (or 74° in Freedom Units) and humidity kept between 35% and 38%.
A Fractal Design Meshify C case (1.434 ft³ volume) housed all the parts. Two 140mm fans were mounted as intake, while one 120mm fan was mounted as exhaust. All fans are BeQuiet Silent Wing 3s. We can’t simply combine their total CFM though. In an ideal world, they would move 2.825 ft³ of air a second. Since we have more intake than output, we will only measure the exhaust. For purposes of this test, we will ignore any excess air that might seep from joints and crevices. So for a very unscientific number, the air in the case is replaced just shy of once per second.
It’s important to remember that any thermal mass, be it metal like a tower cooler or metal as a liquid (such as an AIO) will “heat soak” because heat “stacks,” meaning that heat will add to heat. “Heat soaked” means that eventually the thermal mass will gain more heat in a given time frame than it can release in that same time frame. Using an appropriately sized cooler, you will eventually hit equilibrium, thereby maintaining a specific temperature.
The methodology was to allow OCCT to run until the temperature stopped climbing, effectively hitting that equilibrium. Since I found that took 20 – 25 minutes consistently, I opted to run for 30-minute intervals with a system reboot after each test. In addition, I cleaned the thermal paste off and reapplied it after every 3 tests and between cooler swaps, for a total of nine runs each.

Arctic has a couple of flavors in this line-up featuring 120, 240, 280 and 360 variants. I had the opportunity to checkout the 240 version, which supports two 120mm included fans. These are set to exhaust by default, but you can reorient them to be the source of intake.
It offers an “all-new, in-house” developed PWM controlled pump with a VRM cooling fan. The pump and fans are all controlled via PWM. This means that the pump can slow down during idle, instead of always being at full bore. While on, the fan speeds change depending on load. The cold plate is a copper micro-skived fin design. So if you’re not happy with the included MX-4 thermal paste, you could use a “liquid metal” TIM without the worry of corrosion. Honestly though, you’ll do just fine with the MX-4 paste. The Liquid Freezer II has a bit of heft to it, measuring out at 277 mm x 120 mm x 38 mm and weighing in at 1191 grams.
Arctic’s Liquid Freezer II fits in well with the look of the Meshify C case, in spite of being a bit big and blocky. Likewise, square angles comprise their radiator. They didn’t go trying to round out the radiator frame/reservoir. The tubing appears to be black and silver nylon sheathing over rubber tubing, which adds some subtle texture to the overall look.
Where things get weird is in the pump/plate. For example, a lot more angles and flash are added to the design. It reminds me of a gaming mouse or one of those “gamer” routers. However, it does feature a small fan for moving air around the VRMS. This can often be a point of “dead air” that would otherwise just sit there. While I say that the block is “weird,” I won’t say that I don’t like it. It doesn’t quite resonate with the rest of the aesthetics, but it also isn’t a loud in-your-face design.
I wanted to run the Arctic Liquid Freezer II against the BeQuiet Dark Rock Pro 3. While the latter is a tower style air cooler, it boasts a 250w TDP. It is without a doubt the best air cooler I’ve been able to get my hands on, even beating out some AIOs such as the NZXT Kraken x62.
Over nine separate runs, the Dark Rock still maintained an average of 60° Celsius, reaching equilibrium after about 5 minutes in each test. The Arctic Liquid Freezer II maintained 54° Celsius but didn’t reach equilibrium until nearly 15 minutes later. In effect, that’s a 6° Celsius difference
Running OCCT, of course, is synthetic in that it puts 100% load on your CPU for a given time frame. I would wager that most users won’t tax their systems that hard for that long very often.
The Arctic Liquid Freezer II is a fair bit louder than my BeQuiet Dark Rock Pro 3, though I wouldn’t say it was uncomfortably loud. But if you work with headphones on, you wouldn’t notice, anyway. Sound is a hard thing to quantify without lots of specialized equipment. Moreover, what is “acceptable” is very subjective. I can say that the noise while under load was not much louder than my typing on a mechanical keyboard to write this review.
Final Thoughts on the Arctic Liquid Freezer II
If I were to do it over, I would get this all situated on an open air test bench. That would eliminate any airflow concerns, although I am confident in this round of testing. It would have also made it easier for the swapping of coolers and application of the TIM.
All things considered, the Arctic Liquid Freezer II is a great buy with an MSRP of $75.99. It looks pretty good; it’s not too loud, and most importantly, it cools great. I had already been a long-time user of Arctics thermal compounds. Now, when looking for an AIO for a system, I wouldn’t hesitate to pick up one of the Liquid Freezer II coolers.
[…] from being on an open air test bench, the testing methods are the same as when we tested the Arctic Liquid Freezer II – fire up OCBase’s OCCT and let it run until the temperature stops climbing (which usually […]
I have a Fractal design meshify C mini, I wanted to know if RAM size was a problem if I put the cooler on top? I think I might have a issue
Well we haven’t built in the Meshify C Mini so we can’t speak to that directly. The Arctic Liquid Freezer II is fairly compact. The hoses can be moved and flexed. RAM clearance shouldn’t be an issue as it is with tower coolers.
~ 10F difference BTW not 42.. cant just convert the value like that need to take in the zero value too (0C=32F) 🙂
Hey I was wondering if you had issues hitting the VRM heatsinks when mounting this on top. Looking to get this cooler but I’m not sure if it would fit with my B450 Tomahawk.
I cannot speak to the Tomahawk but there was no issues with the VRM for me. – John
Hi, thanks for the review.
I’ve just got the fractal meshify c myself and I’m lookin at getting the arctic freeze ii 240 on a x570 mobo. From what I can see by looking at the AIO’s dimensions is that its +-63mm… how does the clearance on your ram look?
I’m looking at avoiding rams with larger heat sinks due to this and gravitating towards low profile DIMM’s. Would you say this is prudent or do I not have to worry? I feel like its really limiting my options.
Thanks in advance.
Its been a while since I’ve had this cooler in house and installed. I would say it is something to consider, typically front mounting the radiator would be the better option. As I recall my Crucial Ballistix ram was close to touching the fan shrouds.
Hi, great review thank you,
Im very new to AIOs and recently installed a BeQuiet pureloop into my Meshify C at the front as intake (taking out the intake fans I had before) but Im still seeing less than favourable thermals on my Ryzen 5950x. I mainly use my system for productivity (my work as a graphic designer) with a little bit of gaming but living in a hot country, this has me worrying about temps in my PC all the time!
Im now looking at this Arctic Liquid AIO to try and lower my working temps, and after reading your review, Im looking at changing my configuration to similar as yours (I have plenty of 140mm silent wings fans) and a 120 fan for exhaust at rear.
My question is, are you using the rad as an exhaust in this instance? I seem to see conflicting articles about this and I am very intrigued that you use the AIO at the top AND intake fans separately, at the front, probably for better thermals? I had simply replaced my aircooling at at the front for AIO intake in PULL config. I feel Im not getting the full benefit.
Thanks in advance.
Dean, thanks for reaching out. I am no longer running this setup but typically I prefer running my AIO as intake. I have found with many AIO that running them as exhaust say through the top that eventually the liquid gets “heat soaked” when set to exhaust this tends to happen sooner rather than later. Outside of having it set as an intake, clean airflow and cooler intake temperatures are about all you can do. With the summer heat right now it is difficult.
it wasnt until I sent my question that I realised the age of the original post!! but thank you very much for your response. I hope the arctic AIO will afford me a few degrees better thermals!
