In winter we experienced several weeks where temperatures dropped under 10°C, and recently we faced a heatwave reaching up to 36°C.

I performed some tests this evening, but the room temperatures stayed relatively steady (around 30°C). There weren’t any significant changes while playing games. The undervolt seems consistent, which is positive, and it boosted performance by about 10% (possibly less, but noticeable) during a run of Escape from Tarkov. The benchmark from RDR2 also showed a few extra frames. From what I learned (seeing the video by @Skiiwee29), undervolting adds a bit more CPU speed and improved thermal efficiency per core. Overall, temperatures should remain almost identical. This aligns with your idea, and I definitely agree it was a beneficial trade-off for me.

Certainly, it should also support thermal performance.

To achieve lower temperatures, adjust the PBO Limits instead of keeping them disabled. I typically use PPT 200W, TDC 140A, and EDC 160A with my 5900X. For simple undervolting without extra clock speed changes, set the clock speed offset to 0 MHz. If you wish for higher performance, increase it by up to +200 MHz—but be aware this may cause new issues when the curve optimizer is at -30. It’s better to maintain the current settings and only modify the PBO limits as needed. You can compare performance before and after to see any impact.

I just wanted to mention how I kept the temp under 80°C using PBO on auto with air cooling, top-notch Noctua fans, and an airflow case—my take is that most AIO liquid coolers aren’t built for Ryzen 9s well.

Thanks for the suggestion. I'll focus on using the curve optimizer at -30 and see how it performs. Those two days with temperatures above 30°C might have affected the results, so I'll also consider installing an air conditioning system soon.
