Question about temperature for 7800X3D.
Hello! Your build looks solid with the AMD 7800X3D and RTX 4080. The temps you're seeing during games are quite good—your average is around 65-70°C, which is well within normal ranges for that configuration. Just keep an eye on them while pushing higher loads, but they shouldn't be a concern right now.
Your CPU temps are ideal. The Ryzen 7000 line handles heat by design, with a maximum of 75°C which is perfectly acceptable. You can safely push it up to 85°C without any concerns.
The 75C solid setting suggests you might be reducing performance or clock speed. The chip performs best when kept near its optimal temperature, which the +20C insulator helps maintain. Using the 3D v-cache mod enhances efficiency.
I'm glad you reached out! Reddit definitely makes it feel like the temperatures are terrible!
The temperatures are okay while playing. I keep it in water and stay below 70°C on my 7800x3D. I wouldn’t be concerned about reaching 75°C at the highest settings. Used to run PBO 75c with a -15 cooldown.
Redditors often miss the basics of thermodynamics. The 3D v-cache upgrade reduces the die size before attaching the 64MB v-cache on top of the main part. Silicon spacers are added to maintain proper spacing for the cores, and extra heat transfer layers increase the temperature of the heat source. For a 7000x3D configuration, expect roughly a 20°C rise compared to a standard Ryzen 7000 under typical conditions. This finding came from testing multiple 7950x3D units with both regular and 3D v-caches in the same setup, showing core temperatures differing by around 20°C at the same power draw. I’d argue a 75°C is underestimating performance—either due to aggressive undervolting or direct-die cooling, possibly from a very low temperature limit. A 7800x3D with full core load should reach 80-85°C and hit an all-core boost of 4.8-4.9GHz.
I don’t use maximum settings, so high temperatures probably aren’t a concern for me. I don’t overclock, which means those options are definitely out of the question. Thanks for clarifying how the CPU functions! For your next question, would you prefer an MSI GPU or a Gigabyte GPU? You currently own the MSI Gaming Trio X 4080 Super and the Gigabyte Gaming OC 4080 Super. I have two because I noticed coil whine on the Gigabyte and thought about selling it for an MSI model, but that was a mistake since MSI also has coil whine.
Max 70C seems like you're not going all out. That's why tuning PBO2 to push it to 5.25GHz as often as needed will likely hit its thermal limit, even during gaming. It doesn't really matter much between the two—they both overclock the card to manage maximum power draw. Since the Gigabyte model includes their anti-sag bracket that secures it on the motherboard, I'd choose that card just for that purpose.
With the newest BIOS, I can't even lower the voltage by -10 without risking a post or crash during Windows boot. That's Asus for me! Maybe trying an OC could help, but I'm not sure it'll make much difference.
