I have the 360mm version. It is just awesome. This should really be a really potent cooler. The pressure optimized fans that Arctic designed for their newer coolers actually compare with much higher priced alternatives.

Wow, they should indicate in which cases it can fit.

Alphacool has had a 420mm AIO since at least 2017 ...

Currently called the Alphacool Eisbaer Aurora 420 ...

As to cases. use teh Egg and specify radiator location(s) and radiator sizes. Then check out the selected cases at each vendor's own website just to be on the safe side.

This will fit a Phantec P500a perfectly for my 5950x build oh yeaaaah Intel suck a what lol. Though a 280 or a 360 is more than enough to cool an AMD CPU I just want my system ice cold like a freezer puns intended.

At this point I wish they made a good alternative to EK Custom loop kit with a 420mm Rad.

Knowing the weaknesses of hybrid coolers, I definitely have to see a review of this.
The efficiency curve seems to drop off quite a bit after 280mm.

"Even The Hottest Intel CPUs"?

What about the hottest AMD ones? will it work on those?

This is some bias shat!

It would be nice to see some test results, compared to other coolers of the same size, and other 280mm and 360mm coolers.

I must admit, I am still unsure of how to compare specs of these AIO coolers.

I have a Corsair H115i 280x27mm radiator. On it I've added 2x140mm Noctua iPPC fans @ 2000rpm.
These fans are 182.5m2h, or 107cfm @ 4.18 mmH20

The Arctic cooler has 3 x 140mm fans @ 72.8 cfm, 2.4 mmH2O.

So is this cooler a better performing cooler than the H115i? My fans are often spinning over 1700rpm when gaming and video encoding, and I also have 10 case fans to move air. The intake is the same as the exhaust (it was built to be that way), in a Thermlatake W100 case (I've also tried both negative and positive airflow, but the results are very similar).

Do you add the cfm together to get 214cfm @ 4.18mmH2O since there are two fans pushing air for the H115i, and 218.4cfm for the Arctic? Does the lower static pressure of the Arctic (around 55% of the H115i ), mean lower performance?

So is this cooler a better performing cooler than the H115i?

We really need to see reviews to confirm this, and if so, by how much.
The mechanical weaknesses of hybrid coolers:
A)Pump speed. It pales to custom liquid pumps.
Plus, a larger radiator needs a stronger pump. If nothing is done about that, well... I really can't expect such a large model to best a 280mm - marginally better, perhaps.

B)Size of the copper fins on the opposite side of the cold plate. Bigger is better.

Do you add the cfm together to get 214cfm @ 4.18mmH2O since there are two fans pushing air for the H115i, and 218.4cfm for the Arctic?

I don't believe it works that way, unfortunately, I'm not the person who can answer this for you.
Though the specs you see only apply at 100%. Manufacturers don't post fan curves, so no one could tell you how a particular fan behaves below that; the curves aren't linear.

Does the lower static pressure of the Arctic (around 55% of the H115i ), mean lower performance?

Yes, when faced with 'obstacles'. The more there are, and the greater the intensity, the more air pressure is lost.
-the radiator itself
-the panel the fans are against, whether solid or open mesh
-dust filters
-psu shrouds
-HDD cages
-cable clutter(if present)
-fan grilles
