How to stop the VRM overheating on Maxsun B850ITX in Dead Space 2?
Whenever there was a lot of physics destruction on screen, the FPS would tank from 60 down to 20—the typical ITX power delivery struggle. The VRM on my Maxsun MS-eSport B850ITX WIFI ICE was hitting 102 - 108℃ under load, triggering a hard CPU throttle that dropped my clock from 4.8GHz to a pathetic 0.9GHz. I tried capping the CPU power in software, but that just made loading screens take an extra minute and the lag was still there, which was beyond frustrating. I went for a physical fix: I zip-tied a tiny 40mm fan directly onto the VRM heatsink and set the BIOS power plan to 'Balanced'. HWInfo showed the VRM temps immediately dropped to 72 - 78℃, and the CPU clocks stabilized between 4.2 - 4.5GHz. I actually knocked a jumper loose while installing the fan and the PC wouldn't boot for a second, but a quick manual check fixed it. CPU temps are now 65 - 72℃. The fan is a bit noisy, but it's a fair trade for a playable game.
