How to tune MSI B650M GAMING PLUS WIFI for PUBG?
Whenever I'm looting in dense urban areas, my FPS would just tank from 140 down to 60 out of nowhere. It was incredibly stressful. Checking HWInfo, I saw the VRM temps on the MSI B650M were screaming at 92-98℃, triggering a hardware thermal throttle that crashed my CPU clock from 4.8GHz down to 3.2GHz. I tried disabling PBO Enhancement, which dropped the temps by 6℃ but killed my overall performance by 15%—I felt like I was just handicapping my PC. Instead, I rigged up two 12cm side fans to blow directly onto the VRM heatsinks and set a CPU core voltage offset of -0.05V to cut down the heat. Now, the VRM temps stay between 76-82℃, and frame times have stabilized from a wild 25-45ms to a tight 14-18ms. I did deal with some annoying case resonance noise after adding the fans, but swapping to silicone mounts fixed it. CPU temps are now 65-72℃. My inputs finally feel responsive again, though the fan noise is a bit more noticeable.
