I recently completed my PC build and everything functions properly. However, I noticed the temperature on the 5900x is unusually high. I’m using an NH-D15 cooling setup in a pull-pull configuration because my RAM is tall. Many people suggest this setup is sufficient for cooling a 5900x, but I’m still concerned about the heat. My CPU stays idle at around 50–60°C under default settings (except XMP, SAM, and PBO are enabled), and during heavy tasks like Cinebench it reaches about 87°C—higher than I expected. While some say this is normal for Ryzen 5000 series, the temperature feels uncomfortable. I’ve read about undervolting as a way to lower heat output. I tried reducing the voltage by -0.125V, which cut the idle temperature down by about 10°C and kept it stable at around 40–50°C. The peak temperatures during load stayed under 70°C, never reaching 80. I’ve tested various benchmarks and CPU-bound games without stability problems or performance drops. Still, I’m unsure if the performance is affected. Should I stick to default settings or proceed with undervolting for better cooling? I don’t plan to overclock, just want everything running smoothly without worrying about heat.
The cooler performs well. The temperatures are generally normal for a new Ryzen setup. If you're uncomfortable with the heat, you can slightly lower the voltage. The main concern is that your high-end processor might struggle with stability if you undervolt it, especially since it needs to run 12 cores at around 4.8ghz. Idle temperatures tend to be high because Windows is running and your powerful CPU demands maximum performance for both system tasks and OS operations.
I just watched this video and followed the instructions carefully. I managed to balance the curve by 22 using my motherboard, and it seems stable now. The Cinebench test ran without any crashes, which is good. Temperatures are definitely going down, and I’m checking the hardware info to confirm everything is safe for the processor.
When handling heavy workloads, consider resetting the undervoltage settings and proceed. Ensure there are no stuttering issues during gameplay. I support the video perspective, but there should be a clear explanation for why AMD maintained the stock offset and voltage levels.
I'll remember this, so far certain titles that run smoothly at 144hz show this odd microstutter where the frames drop suddenly from 144 to around 80, making it feel like a sharp lag before returning. It's strange because these issues appear even when I don't interact with the BIOS settings, so it's unclear what's causing it. My reason for playing these games is that they generally have poor optimization, which might be the cause. Thanks!
Those games aren't running smoothly. Hope you have a great chance!
