This was a few days ago, but Hardware Busters finally got their hands on the Arctic P12 Max and it's performance is really good, especially at the price point:

Power draw is a little on the high side though, which could be easily fixed with powered hubs.
(also supposedly the regular P12s have dropped in price so that's a neat side effect of the new fan release).
That's a double ball bearing fan. It should have good service life, but I really prefer FDBs or rifle bearings whenever possible. Or whatever Noctua is doing, which I guess is some kind of hybrid FDB.

That's what this thread is for - for everyone to contribute!


Saw that review too. For AMD it looks excellent, for Intel the included contact frame seems, as said, inferior to third party ones. Glad GN got the 280mm and 360mm versions instead of the 240mm that TPU got.

Funny thing, I ordered a Liquid Freezer II 280 last week for $82. Didn't even have a chance to install and saw the newer version released on Wednesday for $86. Placed my order for the new one and the v2 is heading back. Will be interesting to see how it compares to the H100i PRO I'm currently using on a 7700X build.

One big plus is I'll finally be RGB free...

Looks like we have a winner...

Title is a bit exaggerated. Yes, it's good, especially for that price.

Also from the article:
Without power limits enforced on Intel’s i7-13700K, the CPU will hit its peak temperature and thermally throttle with even the strongest air coolers.
Question is, how much performance would be lost by doing this?

I replaced my Noctua NH-U12S Redux w/ second fan with a Thermalright Phantom Spirit 120. I was expecting better performance but not THAT much better. It's crazy that my top case fans rarely if ever come on anymore. That's pretty damn impressive to me because I can't stand fan noise. Even playing Aliens: Fireteam Elite which tends to ramp up my fans, it was calm and quiet and the temps were ridiculously low. Definitely a winner and I understand the hype, especially for the price. I am using AM4. For the 30ish magic beans they wanted for it, they have a fan in me and I will definitely come back if/when I need another one.

TL;DW:
"The New Best"

Minor complaints:
  • It comes with a contact plate for Intel (required!), which while better than the default ILM, is worse than the third party ones available.
  • AMD mounting is more annoying than Intel.
  • The tubes are really stiff.
If you're like me and prefer a written article, the Arctic Cooling Liquid Freezer III 360 seems to be the focus over the 280mm, although the 280mm looks good too:


Arctic Freezer contact frame not the best but still an improvement over stock. Flatness of the waterblock is excellent. Pump definitely noiser than the Arctic Cooling Liquid Freezer II but looks like running pump at 70% speed is fine. VRM fan is improved. As an aside: did not know GN had both a hemi-anechoic chamber and a flatness scanner now. Way cool.

Noise vs. performance on dual-CCD Zen 2 processor (3950X) looks best in class as of this writing; in terms of outright performance it's not quite the leader but still excellent. GN's Intel testing is pretty limited but plenty of other sites using Intel testing out there.

Arctic Freezer 36 uses a clever fan retention method - screw heads instead of wire clips. "Launch price" shenanigans are a bit cheesy though.
Oooo will have to check later. Pricing looks good-- between this and the Thermalright Phantom Spirit 120 EVO already linked earlier (i.e. Tom's Hardware), looks like we're getting some solid improvements at the more affordable end of the air cooling market (note I didn't say "cheap" or "budget" since the Phantom Spirit 120 EVO is still closer to $45 than it is to $30 or $35...).

If the fan(s) they provide is/are decent, that's an excellent price, particularly considering inflation. It's sort of the new Hyper 212, just kicked up a couple notches. The 212s came with a shitty sleeve bearing fan, so hopefully the PS is doing better.

Techpowerup results for the Phantom Spirit 120 EVO are damned good.

Noctua NH-L12Sx77 introduced, a slightly taller variant on the previous NH-L12S.

Noctua NH-D15 G2 finally announced. A bit thinner, denser fin stack. 8 heat pipes, improved fans, sounds like the offset design might be like the NH-D15S? Some different bases available too.

Their performance testing is nice but their performance rating seems needlessly convoluted.

Also fun:

NVIDIA GH200 cooler.

The biggest drawback of implementing Thermosiphon cooling for PCs is that conventional tubing can wear out over time. While adding metal tubing would last longer, it's not flexible, although Noctua said they have discussed this with system integrators.
I am very curious what they mean by this; once the cooler is installed in a case there should be no mechanical wear at all. Do they potentially mean chemical "wear" on the material of the pipes? I don't know what the coolant is in these thermosyphon systems...

I assume it’s the heat. You’re letting the liquid heat up to its boiling point so it rises up one hose, then cooling it back to a liquid to flow down the other side as I read that.

I really struggle to believe they're actually boiling water in these things, so I suppose it's some other organic solvent as the heat carrier, with a low enough boiling point to cycle at lower temperatures. Methanol might work but not sure whether anyone would want to sell a cooler full of that!

I have to assume they'd use norprene or EPDM rubber for the tubing, or something else with a PTFE lining, for chemical resistance depending on the coolant choice.

Could be water but also at a reduced interior pressure? TBH, I have no idea what it might be. Methanol and its 148.93 degree F/64.96 degree C boiling point means it sounds potentially workable as well.



DeepCool adding a vapour chamber to the Deepcool Assassin IV, making it the DeepCool Assasin IV VC Vision (with LCD of course)? Sounds like a reasonable improvement there too.
