Liquid cooling vs air cooling

[AciÐ #]

Hi im planning to buy a 7800x3d with a corsair 4000d case my idea was to buy a noctua dh15 tower air cooling but cant fit because of ram corsair ddr5 6000mhz so at this point im forced to buy something else i see noctua noctua nh-u12a is good enough for this cpu ? If not i can buy a liquid cooling 240 mm on top case also the other fans are all noctua 120mm

[_I_]

unless the ram is super tall, the tower cooler should fit
use the matching dimm slots farthest from the cpu

240mm ram would be about as good as the better air coolers
they work best as intake so cold air is cooling the rad, its not heating up as much as you think and there are other intakes for cooling the rest and top for exhaust

Noctua is a great option for air cooling. Liquid cooling you would want to check the seals and such after a few years or so. I like the custom models with stainless steel fixtures.

The Noctua NH-D15S would suit your build then. Has recessed fin stack on one side to suit tall RAM modules.

My 7950x3d is cooled with nh-d15s. What you need to worry more is your case. Does it have good ventilation?

[Guydodge]

do yourself a favor and get a 360mm AIO dont play games with a hot running
CPU.

you can put the fan on the other side as pull, makes no difference, or mount its fan a little high if possible

The highest Corsair ram is the Dominator Platinum RGB with 56mm, D15 clearance is 66mm.

I would personally get a Noctua D15S with offset mounting NM-AMB12.

I use corsair vengeance 32 gb ddr5 and i cant fit in noctua dh15 because maximum is 32mm and my ram is 36

Its says also in official noctua site that my ram cant fit in a dh15 so that why i think another option as liquid or dh12

Get d15s

Is the dh12ua so bad has 2 120mm fans 1 intake and 1 out

Buying 240 WC is bad idea, it's marginally better than a *compact* AC at 2-3x the cost and rirsk. (Unless you plan to put the radiator outside of the case, then it's somewhat better, still...

I bought an esports duo for the 7800x3d, expect it to be enough (175W capacity) for my purpose. Though I did prepare to go WC eventually wither with this or a next cpu -- but it will be 280 or 360.

Obviously, the non-compact coolers can easily handle that cpu if your case has enough volume in it. It's a big group to just discuss at bulk beyond generalities that you have to be extra careful on clearings all around: ram, vrms, side panel, etc. For this particular cpu you don't need too much extra, so it's reasonable to look at those just little bigger.

TLDR: if you decide WC, get 280 for top min or forget it. at glance your case looks supporting that, and should be okay with an air cooler too in the situation, there are ones that only extend over 1 ram slot that's empty.

Ryzen 3900X draws more power than yours , so the temp would be better

You're confusing power drawn for operating temperature. There's a correlation but they're not directly locked.

Power draw does determine overall heat production.

It does not determine operating temperature.

A chip pulling 200W on stock cooling will run warmer than a chip pulling 200W on water cooling. But despite running cooler, it's still producing the same amount of heat.

The X3D CPUs do indeed draw little power, but they run warm despite it. This isn't even eclusive to them; AMD CPUs since Zen 3 will generally run up to their temperature limit if they have thermal room available, and they will even do this on good cooling (up to and including the best air cooling).

You get the best thermal (and performance!) results with these CPUs by reducing their voltage as opposed to getting better cooling. Not sure about the 7800X3D but most 5800X3Ds undervolt well (they have a lower frequency they are trying to hit compared to non-X3Ds), but it's still a lottery. Water cooling does help them though, but they're not at all bothered by the higher temperatures on air cooling.

With Noctua you can check specs and compatibility. One of the reasons why you should support their work.

They have all the data right there. No more speculation. Look it up yourself.

I think i will go for noctua nh u12a i dont need overclock and as i see this cpu dont really need an watercooling pc

Illusion of Progress , no , not confusing the two . Just the new Ryzen are the best Ryzen so far .It s hard to find the exact benchmark .

I will go with this noctua u12a since all my 6 other fans are all noctua my pc will have a nice airflow and i dont need to OC the cpu either
