BIOS was updated last evening, but my 3700X starts heating up during idle periods.

Hey there, I see you're facing some tricky issues with your new ROG Strix 570-I Gaming board. The temperature swings on your 3700X CPU are definitely concerning—normally it's stable around 30°C but now it jumps between 34°C and 43°C. You also noticed the CPU frequency shifting from 3800mHz to 4050mHz after updating, and your RAM is resetting to a lower speed. It sounds like you're dealing with a mix of BIOS, CPU settings, and possibly RAM configuration problems. Let's tackle this step by step. First, double-check your BIOS settings for any unexpected changes post-update. Ensure the CPU frequency is locked at 3800mHz and that the temperature thresholds are set correctly. For RAM, verify that it's configured to run at the intended speed and that no conflicting settings are active. If the fans are acting erratically, consider adjusting their speeds in BIOS or using a fan controller with more control. Since you're new to this build, take your time and document each change. Your CPU-Z screenshots will be super helpful—thank you for sharing them! Let me know if you need further guidance.

Fluctuations are typical. My performance varies widely from 40 to 57 when idle. If temperatures stay under 85°C, everything works fine.

The BIOS upgrade might have also adjusted the voltage. 1.320V is a bit high during idle. Unless your temperatures remain within limits while under load, it may not be necessary to make changes.

When it doesn’t need fixing, avoid attempting repairs until the issue is resolved. The updated version is likely causing problems and could be frustrating. Returning to the older BIOS might be a simpler solution.

AIDA64 is currently operating smoothly with a peak temperature around 61°C, which has settled at 56°C. This behavior appears typical, though it's possible the testing conditions aren't ideal.

Yes, you would simply apply the latest BIOS update based on the prior release.

Are you testing the remaining functionality? For an AIO, you need to let it run for 30 to 45 minutes to achieve balance.

Could lowering the voltage to 1.3V improve performance?

You seem to have confirmed your previous setup before upgrading. Did you recall the version you were using?

Yeah, my x570 is behaving the same. This seems linked to voltages that are higher than usual. I notice 1.5v for small loads sometimes. As long as you don’t exceed 95 under load and start throttling, it should be okay. Regarding the lower Ram frequency, it’s likely XMP is turned off now, and you’ll need to re-enable it later. For the fan adjustments, tweak the CPU fan curve so it reaches 50% only after the highest temperature you see when idling or under normal use (like web browsing). Or better yet, set a curve that triggers the fans to increase past 50% only when temperatures hit around 55 degrees.
