I’m uncertain about the second number, but the first one seems like a warning sign—consider getting a new cooler for the CPU. If possible, opt for an AIO setup.

VRM temperature is the concern. Are you employing water cooling? Make sure the motherboard retains enough airflow.

Uncertain about this, but it seems the Gigabyte guide doesn't clarify much. The second number suggests the issue isn't just CPU heat, but possibly VRM temperature – VRMs manage power delivery to the CPU and can overheat if airflow is poor. MOSFETs are part of that setup. So you should boost airflow inside the case, focusing on areas with these parts.

Indeed, this is one of the reasons I asked here...at least someone has some hypothesis about what this is! Thank you for the suggestions and descriptions: I'll try to improve the airflow! Just to make sure I'll try to write to Gigabyte, maybe someone will be kind enough to tell me what that value is... I have an air-cooling solution, but from the beginning I had my doubts about it (I can't remember the exact model of the fan, but it favours quietness over cooling power...). I'm not sure AIO is an option, but I'll keep you posted if I manage to improve things Thank you everyone!!

Standard TR4 coolers usually can't handle the 280W Threadripper Pro. For quieter operation, consider the Noctua 14 TR4 or Dark Rock Pro. Anything else will struggle unless it’s much quieter. The Supermicro SNK-P0064AP4 is a strong option with a powerful fan and fits a 4U server.
