Which cpu cooling is better?

Arctic Freezer A35 CO
Arctic Freezer 34 eSports DUO
Noctua NH-D9L
Noctua NH-C14S

and what be the best choice for 7700X with OC or without OC.

Thanks!

The 34 Duo would probably do the best out of all of those coolers.

It's a 105 watt base chip so the 34 Duo would be the only that you would get sustained higher clocks. I don't have AM5 but if it is anything like AM4 you get your cooling and let the chip do it's thing. You should be able to keep nice high clocks with the 2 fans and tower cooler on the chip.

As a 7700X owner, I'd recommend either a 240 mm AIO, or the biggest tower cooler you can get.

Otherwise, lowering the PPT or temperature target is the only way to prevent it from running at a constant 95 °C in all-core workloads. You don't lose much performance either way, I might add. With a 100 W PPT instead of the factory default 142, you'll be looking at approximately -5% performance which won't manifest in games.

With Zen 4, you don't match your cooler to the CPU. You just buy a cooler and adjust your settings to match it. The better cooler you get, the more the CPU can take.

Oh, and forget about OC. These chips run at their max capacity by default, which you can't match with an all-core OC.

D9L is not even remotely in the same realm as the others. It's weaker than the U9S and other normal 92mm towers. You don't use a D9L unless you're height limited to less than 125mm.

If you run a C14S with good airflow (its own direct airflow from side panel), good exhaust, and one fan you can expect around U12S-level performance. Not impressive for the C14S' size or heatsink mass - the point of the C14S is limited height RAM cooling.

If you run a C14S with bad airflow, bad airflow path, and bad fan orientation you can expect to cripple it to around U9S level performance.

Pretty sure the A34 Duo is your best bet out of those.

But I would just go for like a Thermalright PA120SE for a 7700X. Wouldn't be surprised if it lays the smack down on the Arctics while being cheaper.

Just remember that vague recommendations like an AIO are meaningless since some AIOs are pure garbage, and performance varies wildly - going by radiator fan sizes mean nothing when the could be thin alu rads or double thick copper ones, along with every other change to them

D9L is a short cooler for better compatibility, but that reduces its performance
C14S is the same with its down-facing nature

why are the two noctuas their smaller, lesser performing models?
No Be quiet options?

Freezer 34 and 35 have the squished heatpipe design i hate for modern CPU's, the gaps between the pipes - no matter how small - can be terrible for performance if they dont line up well over your CPU chiplets on AM4/AM5

Can you link us to the shop you plan on buying from?

Heres an example of the direct heatpipe design, from the freezer 34 review specifically

Low wattage, performed amazing

double that wattage to 135W, and it falls to middle of the pack

both of those are on the ryzen 3000 series which do run chiplets, but also dont have the heat density issues of the higher end 5000/7000 series CPUs

That's why I recommended at least a 240 mm one. Even the cheapest one of those should be okay (not good, but okay), not to mention 99% of AIOs come with standard 25 mm thick alu rads. Their biggest difference is the pump design, which isn't a big concern.

@khjhpopasa What do you intend to use the CPU for?

 

[Mussels]

Too lazy to paste all the screenshots again so here's a screenshot of another thread i'm discussing the same issue on

You can literally see the heatpipes on the pressure testing, as well as a sudden lack of pressure either side of them

This is what the 5600x and 5800x look like - the CPU cores are the "AMD" die

Zen4 looks like this, with your 7700x only using one die like the 5800x image above, not the two in this image

This was fun to figure out:

They face like so:

With the pegs above and below the text

The Freezer 34 can only be installed one way, like this:
Meaning the heatpipes run vertically

Since they use the stock AM5 brackets that means like this

This is NOT perfectly to scale as i couldnt find truly flat images of the baseplate to work with and my example squares arent even level - but it's worth noting that you may only get 2 heatpipes worth of cooling on the CCX's with the fourth helping the IO Die and the 3rd taking a bit of heat from either one

On lower wattage CPU's these designs perform fine, but i would not trust anything without a solid baseplate for AM4 and AM5 CPUs

as I see it will be amazon

In that case the Thermalright Peerless Assassin 120se that @tabascosauz suggested will destroy all of the hs you have listed. 154mm tall and clears tall rgb memory by adjusting the front fan up, or you can run the fan in the back position and lose zero performance.
$40 or $50 for the black/white or rgb versions.

Yup looks like Thermalright is back

Nice to see other people than me recommending them
