Hey everyone! So I recently helped a friend build a PC, and he's been dealing with some pretty high CPU temperatures while gaming. Specifically, the Ryzen 7 9700x hits around 81°C to 82°C during demanding games like Helldivers 2. We're using an MSI PRO B850-P WIFI motherboard and I'm a bit of a novice when it comes to undervolting. So far, I've applied a -0.04V offset, which seems stable and has helped a bit with the temps. I'm wondering how much more I can safely undervolt the 9700x. I know someone who undervolted his 5800x3D by -0.1V and it worked fine for him. Any advice on how far I can go with undervolting without risking stability? Thanks in advance!

82°C is actually pretty reasonable. People often panic when they hear anything above 80°C, but as long as it's under the max operating temp of 95°C for the Ryzen 7 9700x, it's not a huge deal. I used to undervolt, and at one point, I went with a -25 curve, but that made my temps shoot up to 95°C! I switched to a 105W TDP and suddenly saw them drop to 75°C. It’s all about balance.
Instead of undervolting, you could consider using Eco mode. It's a safer option that slightly reduces performance but significantly lowers CPU heat. You can also try the curve optimizer with a -10 offset. Just remember, the lower you go, the more stable your system could potentially become. By the way, what's the cooler and case you’re using? Temperature management can also rely heavily on those.
Honestly, 82°C for peak package is pretty normal, and not really something to worry about. I think your friend’s CPU is doing just fine at those temps, especially during intense gaming sessions. You might want to keep an eye on it, but it’s not overheating by any means.
