How to fix VRM overheating on MSI A520M-A PRO in FS25?
The power delivery on this board is basically naked when simulating massive crops; every time I loaded heavy machinery, the system just handed me a Blue Screen of Death. The VRM temps on my MSI A520M-A PRO were hitting 102-108℃ in minutes, which obviously triggered the hardware thermal protection. I tried stuffing three extra case fans in there to blast the motherboard, but it only dropped the temp by 4 degrees—absolutely ridiculous. I finally gave up and went into the BIOS to cap the CPU max boost at 4.2GHz and forced the VRM fan curve to a constant 100%. In OCCT stress tests, the core temp leveled out at 70-76℃ without any voltage drops. I actually froze the system at the loading screen when I first tried undervolting, and only got it working after tweaking the Vcore offset. Now the fans sound like a jet engine taking off, but at least I can play for three hours without a crash. I've cleared the event viewer logs and confirmed fan speeds are steady at 2200-2400RPM.
