Your 7800x3D temperatures are within typical ranges.
I have limited experience with temperature monitoring, but I set up the MSI afterburner and had my temps tracked. They seem to stay around 47-48°C during normal browsing, which appears acceptable. However, when I watch YouTube, my temps rise into the mid to high 50s, though I suspect some fluctuation from checking the board or pulling up the screen. During gaming sessions, I usually see temperatures in the 60s, sometimes reaching 70-71°C, but that’s rare. I reinstalled Siege to get back into it after a console period, and it works well—temperatures stay around 69-75°C with no FPS cap, which helps keep things stable. It’s still a bit warmer than some games like Uncharted 4, but it’s manageable.
Execute Cinebench R23, it's the top choice for checking your performance window. The processor needs to maintain around 4.8-4.9GHz across all cores and hit roughly 18k points. If not, you're likely experiencing thermal throttling during a full-core task. Usually, a 7000x3D run will approach its thermal cap easily. The ideal target is 5.05GHz all-core, which fully activates the chip's 50.5x boost factor. Going beyond that requires base clock overclocking—a challenging option with modern PCIe SSDs.
The reason 70°C feels "ice cold" comes from modern CPUs adjusting their speeds dynamically. They can exceed their rated boost clocks, which doesn’t cause issues for Ryzen, particularly with AM5 chips. The idea that 3D chips avoid thermal limits due to cache isn’t accurate—thermal limits apply regardless of architecture.
The thermal threshold is reduced in comparison to the standard 7000 series, while the 3D v-cache CCDs are secured. R7 3D runs at 50.5x and R9 3D CCDs at 52.5x. The non-3D R9x3D models measure 57.5x yet I've observed them reaching up to 5.9GHz, making them more akin to a typical Ryzen 7000 CCD though constrained by the 3D variant. PBO2 support was available on Ryzen 7000x3D as well, unlike AM4's 5800x3D. I suspect the 5600x3D and 5700x3D models are essentially identical, which hasn't caught much attention from me. Ultimately, they hit a voltage/current ceiling preventing performance beyond 4.9GHz across all cores; I've lowered my 7950x3D to as low as 2c/4t on CCD0 (3D) to test if it could sustain 5.25GHz, but it fails. The thermal boundaries set by the 3D v-cache module are quite restrictive, though a delid solution seems possible—something I've resisted doing multiple times. The top CPU choice at the moment would likely be a delidded 7950x3D with CCD1 disabled, although I lack the confidence to try it, even though Noctua offers a delid mount for my NH-D15, which would cost around $100—a reasonable price.
X3D won't aim for the sun, that's right. The standard chips will handle it.
Sure thing. My older intel HEDT chips run reliably in the 50s-60s under load with a solid cooler. Yet they only reach 3.1-3.6GHz allcore, while those same chips can hit 4.2-4.5Ghz or more. I force them to those speeds and temperatures spike significantly—reaching the 70s during games and the 80s to 90s under the most demanding synthetic tests. Newer chips handle overclocking automatically, starting at 5.0GHz or higher (many top models even go to 6.0 on a few cores), drawing more current in the process. Their compact size also limits heat dissipation, which leads to similar high temperatures despite better efficiency compared to older models.
In short, I can accomplish this task effectively; others likely could too since I didn’t need any adjustments beyond setting PBO/CO. The specs include 7800X3D - PBO, -30 across all cores, 4.90GHz all-core, 5.05GHz single-core, 18286 C23 multi, and 1779 C23 single.
