Arctic Liquid Freezer ii 360 or 420 for 13700k

[Shiznet]

Hello all, I am trying to decide between these two AIO's and I am wondering if anyone here who owns either of these can tell me your temps for high wattages exceeding 200w or full load cinebench test if possible. I have been searching extensively and I can't find very good info for this. Theres some for the 420 but not much for the 360 when it comes to high wattages like 250 and above. Even Gamer Nexus which is quite thorough won't test over 200w, the general consensus is the difference is marginal, however I am wondering for very high wattages on CPU's like the 12900k, 13700k, 13900k and above if the 420 begins to SIGNIFICANTLY beat the 360 or if it remains marginal.

I would greatly appreciate this info, thank you.

Extra surface area for air coolers and radiators is usually helpful but a 360 would still be fine

Arctic 420 is the best AIO on the market while costing way less than some competing products.
However the difference is not huge and very few PC cases can fit the radiator on top. More cases can fit it in front but then you compromise on case air flow and RAM, VRM, GPU cooling.

The difference should be a bit bigger beyond 200W but not dramatically.

I've seen this video and watched, as well as others my question is if once you tested over 200w like 250w and over would the 420 begin to outperform the 360 more significantly at such wattages

I guess I'm just curious how significant the difference is or how it would be at higher wattages. Can't seem to find good results for this, like I wonder if a CPU was pulling 250-300w if the difference between the 360 and 420 would go from marginal to significant due to the larger rad. Difference shows to be marginal but thats when tested to 200w.

At this point its more of a curiosity thing lol.

I got a 420 off their outlet/refurb store on eBay like 2yrs ago. Was a few degrees warmer than custom parts (aquacomputer, hardware labs, D5) running a 280mm rad but it's worth it for around $100 USD.

It's big though. When using EATX with a Core P3 I had to drill mounting holes, have had to use a vertical graphics card mount for long cards too.

Look compare of 280 vs 240. I expect the ratio be similar between your 2 choices.

If I had a case that can host either in the same position I'd just blindly go with the bigger.

Hm, I have some reasons as to why I might go with the 360 instead or at least for now but at this point I would like to know out of curiosity lol. I do have a case that can host both.

It won’t be too much of a difference and running the chip at 300+ watts isn’t advisable nor ideal.

It’s tested at 200W because it’s more reasonable and easier to handle.

If you just want a 360 that can cool as well as the 420 and are open to other brands I just happened to watch a video on the Lian Li Galahad II Trinity and he was able to run a 13900K at 325W without thermal throttling. Disclaimer: I've never watched any of his videos before and can't really say much on his test methods (not sure if he was testing cold or let everything come up to temp) but he did specifically say it was on par with the Arctic 420. I personally have a Galahad 360 with AL-120 fans and my 7950X3D barely ever sees 50C in real world use.

I understand that, I guess im just curious but also trying to get an idea on just how much a 420 radiator could handle for future CPU's, power spikes, etc. I don't necessarily think if ever hit those wattages but I guess I just want to know or want to be safe as well. I lean to the 360 more but if the difference was for sure significant I would go with 420. The 13700k can get up to like 257w or something, probably extreme Conditions though.

Hm, I really like Arctic but the reason I haven't mentioned for me leaning to the 360 for choice is aesthetic. I have AL120 fans I like but changed my mind to the EVO XL but still want to use these fans. There is no 14p for the v1 variants I just kinda worry the 420 would dwarf the other fans and look weird, maybe it wouldn't but it is a thought. 360 I could mount my AL120's in white possibly and the lower profile probably just looks better in this specific case for me. I am doing a black and white contrast type of build so I've been picky with my parts but not to the point of harming performance for aesthetics, I would only do it if its extremely marginal.

That being said I am honestly just curious on this matter even if I choose one of the AIO's. Its a question I want answered I guess.

Here a guy is testing the 14900 and his 360mm is not enough even on stock CPU settings - no overclocking.

So even if the difference is 3C it can be a difference between thermal throttling or not.
On the other hand I'm not sure if a 400W CPU is the future.
