Reducing the power supply to my processor causes the machine to stop working and then returns to its default settings.

You're trying to reduce your CPU's voltage to avoid overheating, but adjustments via MSI Command Center often cause the system to crash or reset, erasing your changes. Using BIOS, you can manually lower the voltage, though it may trigger a shutdown and restart. Your current AMD FX-8350 at 4.2 GHz on an MSI MS 970 board is running hotter than usual after these attempts. Any advice?
Looking for a CPU cooler? Check the ambient temperature, idle temperature, load temperature across all cores at full speed. Would it help if we try resolving the cooling problem first rather than focusing on voltage issues?
Looking for a CPU cooler? The temperature readings you mentioned are concerning. When idle it's around 30, but under load it spikes to 78-79°C, and sometimes it shuts down completely. If cooling improves, it might be easier, but replacing the cooler could be costly. I’m also unsure if my motherboard supports it or if I need a compatible one.
Ambient temperature equals room temperature. The PC draws air from the room, which is why hot shutdowns become a significant issue. We need more questions to figure out how to boost cooling affordably. Are there any spare fans or thermal paste available? If yes, take the fan and shroud off the CPU cooler, install a bigger one—92mm should fit. Clean the CPU and heat sink paste, secure it in place. This approach is similar to what AMD used for the Wraith Prism, featuring a larger fan with noise controls. It's interesting since I also use AMD fans for cooling my Intel VRM and memory.
I don’t have any extra fans on hand, and regarding thermal paste, I’ve already updated it some time ago, but it hasn’t made much difference to my issue. Would you like me to try removing the voltage instead?
The system shutdown might be linked to voltage adjustments. Certain BIOS settings behave this way. My first step would be purchasing a higher-quality cooler. I’m aware my old FX-8150 overheated even when idle. What cooler is installed? If you plan to cut voltages, you’ll need to lower the clock speed as well.
You only have your case's fan and the CPU's built-in cooler. No extra cooling solution. For voltage adjustments, you should reduce it gradually without changing other settings. The CPUNB value offers fine-tuning options with many decimal places—stick to the recommended range based on your current temperature. Avoid making big changes unless necessary, and save a cooler for when it's truly needed.
The CPU comes with a cooler, correct? Is it a built-in one? It seems to be located on the motherboard. You probably don’t need to adjust anything. The only settings that really matter are the core voltage and multiplier. Underclocking potential depends on both the CPU model and your expertise.
It's a stock cooler, but I'm not familiar with it. Can you explain what you're trying to do?
