7800X3D can it be air-cooled?

Deciding on this CPU or the 7700(non x) for a pure gaming build. I don't benchmark I just game on it. But I'm worried about it not coping on an air build.

My plan is to hav a noctua NH- U12A
The case will have 3 120mm fans at the top and 1 at the back. The graphics card will be a Nvidia 4070. I will be playing at 1440p aswell. I will not be upgrading for a good 4-5 years and if it's still relevant I hope to drop a new chip and GPU in then.
 
We're using a Noctua NH-U14S for temperature measurements. Application temperatures are measured using Blender, a highly demanding rendering load, which will load all cores completely, but that's still realistic and not a synthetic stress test, like Prime95. For gaming, we picked Cyberpunk 2077, its modern engine is multi-thread aware and will try to spread as many tasks as possible over a large number of CPU cores, when available. Even when a game uses multiple threads it doesn't load each CPU core as heavily as rendering, for example, so there's some scope for power savings here.

 
I would think it will be fine, I ran a 7950X with a Wraith Prism for a week until I sorted a better cooler. The fan ran at full blast, but it was fine. The Noctua NH- U12A is MUCH better and the 78003D uses less power so should be fine. I would add (2*140mm or 3*120mm) fans as intake on the front of the case.

Unfortunately the case won't allow fans at front as the PSU is stacked there. Asus ap201 mesh build.
 
Awesome I'm sold, can't wait to start building next month.

I currently have a intel 6700k how do they compare for gaming performance?
For gaming, 7800X3D makes 6700K look like it's from 2003, to give you an idea. :p

Seriously though, it's a significant jump, even going from Ryzen 9 5900X that I had previously, the jump was massive.

I've got a 7800X3D cooled by a U12A - it's more than fine.

I upgraded from 8700K and it was a night a day difference.

Even from that CPU. I always thought that there only small performance increases with each new CPU. Didn't think my 6700k and your 8700k was that far back compared to the 7800x3d. Very glad to hear it obviously, just surprised that's all.

I’m still on a 5900x with a 4090 but at 4K based on the research I’ve done I’m not convinced there’s that much of a notable difference going to a 7800x3D?
Probably not a huge amount at the high end, minimums could be a different matter. The X3D chips do seem to smooth out the experience. If you're happy with the current performance I'd wait as the 7800X3D is only going to get cheaper over time. You can then jump to a new platform.

A friend of mine upgraded from a 5900X and RX7900XT to a 7800X3D and said the jump in performance was massive. I’m not sure what games he plays.

Looks pretty decent gains just for a CPU and that's with a slower graphics card, though it does vary depending on the game/resolution.

This video uses a 4090 and compares the 5800X3D, 7700 non-X and 7800X3D, @ 1080p, 1440p and 4K:

For the record, the 7700 non-X actually comes bundled with an air cooler (wraith prism) and TPU's temperature results have the 7700 non-X higher than the 7800X3D (when gaming), so theoretically it could have been bundled with the same cooler.
