How to fix VRM thermal throttling on Biostar A320MH PRO?
The second I slip into a target building, my frames dive from 60 down to 35, and that choppy feeling is a total nightmare for a stealth run. Checking HWiNFO revealed the Biostar A320MH PRO's VRMs were hitting a brutal 98-105℃ under load, triggering an immediate thermal throttle. I tried slamming the OS into High Performance mode, but that just pushed core temps over 100℃ and made the stuttering even worse—software tweaks are useless against a physical heat wall. I eventually dove into the BIOS and manually locked the core voltage at 1.15V while dropping the fan response time to 0.1s. According to RTSS, my frame times finally tightened up from a wild 16-42ms swing to a steady 12-15ms. I did notice some annoying coil whine after the voltage lock, but that vanished once I tweaked the load line to Medium. Now the CPU sits comfortably between 72-78℃, and the experience is night and day. I saved these tweaks to a BIOS profile, and the frame times are rock steady at 12-15ms.
