After playing Gears 5 for a while, my ASUS TUF B760M-PLUS Artillery starts dropping frames due to VRM overheating. Why does this keep happening?

During high-intensity matches, I noticed the VRM temps swinging between 92-98℃. It didn't shut down the PC, but it triggered aggressive CPU throttling. I first tried disabling all power-saving features in the BIOS, but the FPS just hovered between 50-65 without any real gain. I then went into the fan control and switched the VRM fans from 'Auto' to 'Manual', setting a steep ramp-up curve starting at 85℃. In HWMonitor, the power delivery temps stabilized at 82-86℃, and frame time jitter dropped from 11.2-16.8ms to 8.4-9.7ms. I actually tried overclocking the RAM first, which just made the system unstable. After two hard reboots and rolling back the XMP profile, I realized the VRM stability was the actual bottleneck. The fans are pretty loud when they ramp up, but the clock speeds stopped jumping. I verified everything with a Cinebench stress test, and frame times are now locked at 8.4-9.7ms.
