Arctic Launches Liquid Freezer II 420 AIO Liquid Processor Cooler
An XXL expansion: with three 140 mm P-fans and a 458 mm length radiator, the Liquid Freezer II 420 is to date the largest and most powerful variant of ARCTIC's water cooling series.
Developed for massive cooling performance, the formidable CPU cooler comes with high compatibility for all common Intel sockets as well as AMD's AM4 and AM3 (+). In conjunction with distinctive features, such as a self-developed, PWM-controlled pump; a 40 mm fan for cooling the motherboard voltage converter; and the proven, pressure-optimized P-fans (characteristic of the entire Liquid Freezer II series), the Liquid Freezer II 420 joins the series in setting the highest standards for CPU water cooling. Since entering the market, the all-in-one series has won over hardware enthusiasts and independent tech reviewers around the world. After receiving numerous awards for performance, value and operating silence, the Liquid Freezer II 240, our dual 120 mm PWM fan variant, was also awarded the coveted European Hardware Award 2020 in the category "Best CPU cooler (water)".
With the additions of the Liquid Freezer II 420, ARCTIC's CPU water cooling series currently comprises a total of five product versions. Due to the long hoses and the availability in different sizes, the Liquid Freezer II can be used in a variety of ways, from small form factor PCs to big towers
- Compatible with Intel & AMD sockets
- In-house developed, PWM-controlled water pump
- High performance enables overclocking
- Motherboard VRM cooling solution
- Fans optimized for high static pressure
- Fully sheathed hoses
- Integrated cable management
- Maintenance-free water circuit
- Secure hold thanks to backplate
The Liquid Freezer II 420 is available now at a price of $150 / 135 EUR.

I until recently used a 120, and while the performance was always good both the 120 rad fan and the small VRM fan got noisy over time, so in less than a year I stopped using it.
I received a replacement for the 120 fan from Arctic, but it too developed a bearing whine after a few months.
Running a Fractal Celsius 240 now.

Nah bro, I have the 280mm version of this and I have never ever heard that small VRM fan, not even once,.,,and it IS spinning. The radiator is so thick, I look at my old corsair 240mm radiator and it looks like a toy in comparison. AND, that lil vrm fan is NOT useless, unless you want to disagree with Steve at GamerNexus and his review of this AIO. Also, you don't have to control everything off one fan lead. It is very easy to run the fans off the MB's CPU fan headers and have the pump and VRM connect to the pump header if you choose. I was gonna go this route, but ended up letting the CPU fan header control everything and I couldn't be happier with the performance. (3800x here).
Seems like a great cooler since it has a 1.5 inch thick radiator instead of the standard 1 inch that most AIOs come with. One thing concerns me though. How would you control the VRM fan on this thing? Unless I am mistaken there is not any software for this thing so the VRM fan would be tied to the CPU temp or something and would spin up and down all the time. As a Ryujin 360 owner I know how loud these small fans can be so I set mine to a static level in the Armoury crate software. In the Asus AIO only the pump speed is controlled by motherboard and the other fans by software.

I can only agree to Rx4speed's post!
The VRM-cooler is totally inaudible in a closed case.
And while have it mounted upside down, it keeps my 960pro (on which I added a M.2 heatsink) @66°C Max. under torture.
I'm reeeally curious to see what results hilberts review of this AiO brings (hopefully ;] ).
Anyway -> My 3900X stays below 70°C with my 240 @4.2GHz allcore... and for that price (t'was 69€ in january), it's an absolut nobrainer!

I have the 280mm model, it is quite and has a great cooling performance, however the Vrm fan is more about look and completely useless. 2nd, i did a di-lid to the cpu. but when installing it, it will touch the capacitor in the motherboard z390, so wasn't able to use it straight to the cpu die. Fans,pump vrm fan are all controlled by 1 plug.
i do not think there will be a huge gain between the 420mm and the 280mm, maybe 1-2 degrees
Everything is great about it except the pump/block/vrmfan design* itself
Did not Steve just reviewed it and found the vram fan would reduce vram temp by 4 celcius or something like that. Would not call that useless personally.

Hehe, mine isnt flash enough to win an award. It looks great from the outside because you cant tell a PC is inside it apart from a small amount of air whoosh.
Interesting someone else built a PC inside a table, I missed that. Mines been like this for 4 years, it was a great idea.
I'm not sure what you mean by a single wire?
My fans also run from the mobo, no sense using another power supply, they hardly use any power.
The loudest noise is from the GPUs Arctic Accelero III cooler which is pretty quiet (always on full speed).
Although there is a drive that rumbles quite a bit which had to be mounted on a bit of packing it arrived in to stop it using the case as a sounding board!
(everything is sat on carpet inside the table, the mobo is mounted on a metal motherboard tray. Most drives are mounted in drive racks, both nicked from my last case, or just sat upside down on top of the PSU/drive bays. A silent 230mm fan blows air past them.)
