AIO or Air Cooler for 7800X3D? Please help, recommend

[yajdem]

Hello!

 

I would like to ask you for help.
I am looking for processor cooling for the following configuration:

• Motherboard: Asus Strix B650E-E
• Processor: AMD Ryzen 7 7800X3D
• Memory: G.SKILL 32GB KIT DDR5 6000MHz CL30 Trident Z5 NEO RGB
• Case: Corsair 5000D Airflow

Basically, I like the Aric Liquid Freezer II 360mm among the AIOs.
As for air cooling, I like the Noctua NH-D15S and the be quiet Dark Rock Pro 5 the most, but I could also include the Jonsbo HX7280.

 

I looked through the CPU Cooler Performance Tier List and saw that the liquid freezer is among the best.

 

What should I choose?

 

I'm a little worried that the AIO will leak, but in the meantime I want the processor to be "cool".
What happens if the pump breaks in the AIO? Does the processor fail?

 

What do you think would be a good solution?

 

What is important is that I buy a new processor cooler every time I build a new PC, so it is replaced every 3-4 years at the latest.

 

Thank you very much!

All three of these coolers are insanely overkill. The 7800X3D draws no power and therefore can be adequately cooled by a stock cooler, let alone the top end air coolers. 

 

Just get something cheaper. The Thermalright Peerless Assassin 120 or one of its derivatives is usually a pretty good option.

Depends on how it breaks. If it develops a leak in the cold plate (very rare but can technically happen), then it does have a chance to kill the CPU. If it's just the pump failing like is significantly more common, then your system will just start overheating within a minute or two of turning on, or it will come up with an error saying something like "CPU PUMP failed, replace immediately" and prevent the system from turning on until you get a new AIO. This doesn't usually start to happen until 3 years at the minimum, 5 years on average though, so not something you realistically need to worry about.

This is not an engineering question, this is all style. If you want liquid cooling because it looks neat, get down with your bad self! You will have to blow the dust out of the radiator regularly, which is a PIA. If you don't care use the stock cooler or the one that makes you happy, any good one will do. A BMW is more expensive to maintain than a Ford Focus...its the same story.

Do you think that I can't achieve better temperature values with an AIO than, for example, with a Noctua-NH D15S?

Not meaningfully better, no. A ~$35 air cooler will keep the chip at ~60C in games, with an ~80C max in all core workloads assuming a standard 21C room temp. More expensive and better coolers might get 2-3C lower temps if you're lucky, but given that they're already so good to begin with and these chips don't have overclocking support, it makes no sense to seek out a higher end cooler for them. 

[SillySlug24]

Here is a way too complex dive into chip temperatures if you want to go down the rabbit hole:

https://www.linkedin.com/pulse/what-proper-temperature-ic-chip-kuke-electronics

 

Due to thermal resistance there is a maximum limit to how fast heat from the silicon chip can be passed from the chip -> to the TIM (Thermal Interface Material) -> to the heat Spreader -> to the Heat sink/cooler/radiator-> to the outside air. As long as the TDP of the cooler is greater than the TDP of the CPU you are fine. If the CPU die, the actual silicon chip, is less than 89°, Tjmax, there is no gain in performance. If the die does reach tjmax the CPU will throttle to protect itself lowering performance. Any good air or AIO cooler will keep you from reaching tjmax even under max load.

 

In short, do what gives you joy, but 2-3° diffs in temp will have no effect.

 

Side note, many people, when installing their cooler use way too much Thermal paste. The best possible conduction of heat is metal to metal from the heat spreader on top of the CPU to the cooler. Thermal past fills the *tiny* gaps between the spreader and cooler, increasing cooling surface area. More is not better!

I dunno, I built my 1st computer in 1994, have a Computer Science degree, and Job in IT. I sent you to an article from an electronics manufacturer who Actually Make Custom Silicon explaining temperature and conductivity. That guy has a YouTube channel and 2.69k subscribers. You decide.

That was done with a 5800X, a CPU that has completely different cooling characteristics. I'd be less likely to trust some random guy on YouTube with cooler testing than one of the Bigger names like Gamers Nexus, though their testing showing the Liquid Freezer II 360 being the better cooler lines up (there are still better air coolers than the NH-D15 though). 

 

Besides, even if that was true, that still doesn't change the fact that the 7800X3D doesn't need high end coolers because it just doesn't run that hot in the first place. 

 

His testing showing that it runs cool with any cooler is backed up by other reviewers as well.

Your video confirmed that.

NH-D15 vs Arctic Freezer II, the difference is 0*C ~ 3*C difference at 130W, depending on the fan speed %.

My 58X3D is no harder to cool than my 5600X. All this talk of X3D being hot is just regurgitated hype imo..

 

I can run it with no fans installed on all of my air coolers, I have a few..

 

[RevGAM]

The only reason to get a top cooler for a cool CPU is if you plan to reuse it with a different one some day. You started that you don't do that, so there's no need to throw big money at this CPU.

[freeagent]

If you have good case flow you could probably run that cpu with no fans installed on the cooler like me.
