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.

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

Thanks for the info.
The bumph says it never needs topping up due to the weirdy woo pipes (believe it when I see it) and well, it'd be cool to see how fast my screwed up 6700K can go.
An AMD 5xxx cpu is incoming anyway, it can go on that later for the real showdown, and this AIO looks like a sweet performer.
Plus it will remove heat from the GPUs cooling area.
I ordered a 420mm version, should be here at the w/e or just after.
Finally some fun to look forward to after the 3080 no show.

I'd get one if my case would allow, stuck with 280mm version, one tiny wire runs the whole system, very tidy. Super quality rad too.

Fortunately my PC is mounted inside an open backed coffee table, the radiator will be placed underneath it so the heat gets nowhere near my GPU.
Its a pretty good solution if you have the floor space, air in and out to the GPU are provided by 230mm fans and a 1 inch gap under the table surface all the way round for any hot air that rises.

I run the fans off my mobo, many folks do this to lessen stress on the single wire. A recent rig of the month was inside a table too, gets you thinking!

I have the 280mm version, and you cannot hear the VRM fan while in operation.
