Is VRM overheating causing lag on MSI B760M-A WIFI?
Whenever I tried to launch a massive attack in the middle of the fray, the frame rate would just tank, and that feeling of helplessness in a competitive match is just infuriating. The VRM on the MSI B760M-A was hitting a scorching 98-105℃ under load, which triggered a brutal CPU throttle, dragging my clocks from 4.8GHz down to 3.2GHz. My first instinct was to lower the CPU power limit to keep things cool, but that was a fail—my 1% lows dipped to 40 FPS, which is unplayable. I ended up going into the BIOS, switching the CPU fan mode from Smart to Full Speed, and remapping the top chassis fans to exhaust the heat faster. HWInfo showed the VRM temps finally dropping to a manageable 78-84℃, and the stuttering basically vanished. It was a bit of a struggle at first because the fans were so loud they caused the whole case to vibrate, but dialing them back to 1800 RPM hit the sweet spot. CPU temps now sit at 72-78℃, and the input response is finally snappy again.
