How to stop VRM overheating on Maxsun B850ITX WIFI ICE?
It's absolutely insane that an ITX board could let my CPU trigger thermal protection and crash right in the middle of a massive fight—it was a total disaster. The VRM modules on the Maxsun B850ITX were screaming at 105-112℃, causing the core voltage to dip by 0.1V, which just killed the system. I tried capping the CPU at 65W, but that was a joke; my FPS dropped from 120 to 70, and I refuse to neuter my performance like that. I ended up flipping my case fans to a forced exhaust setup and set the Load-Line Calibration to Level 3 in the BIOS. In OCCT, the VRM peak temp plummeted from 112℃ down to 82-88℃, and the crashes stopped entirely. I did get some annoying case resonance after changing the airflow, but some silicone dampening pads fixed that. CPU temps are now a steady 75-82℃ without the clock jumping. Power parameters are backed up in BIOS.
