Hey everyone, just wrapped up setting up a friend's PC with a Ryzen 5 3600 and the mentioned motherboard. Temperatures were quite high both when running and when idle, so I checked the voltage settings. The default Vcore was around 1.45V. After undervolting, full load temps dropped to about 55°C without any performance drops. Curious why MSI includes such high voltages in their BIOS?

What is the maximum temperature range? Expect around 70 to 75 degrees, which is normal, particularly with the stock cooler in place. How were these tests conducted?

All motherboards start with low voltage by default because it’s safe. They add extra power just in case the cheapest chip fails. It seems they sometimes push it even more than needed, which is why I usually adjust it myself.

I performed Cinebench tests between runs. No score drops were noticed, suggesting stable performance. The stock system didn’t reach full load temperatures; fans increased significantly, prompting a voltage reduction. Now it operates at 0.25V lower, which I find substantial. The cooler is robust enough to prevent overheating. I used a beQuiet! Shadow Rock 2 with 180W TDP, which should deliver strong cooling for the CPU.
