Stopping MSI PRO B760M-A from overheating in MS Flight Simulator?
Man, the second I hit the throttle for takeoff, the whole PC just went black. I thought my PSU had fried, but it was actually the motherboard VRMs giving up. On the MSI PRO B760M-A, the power stages hit 105℃ when the i7 hit full all-core boost, triggering a hard hardware shutdown. I tried slapping three 120mm fans on the chassis, but the noise was like running a factory and the temps only dropped by 3 degrees—a complete waste of time. I eventually went into the BIOS and manually set the PL1 and PL2 power limits to 180W and undervolted the CPU core by 0.05V. HWInfo showed the VRM temps plummet from 105℃ to a manageable 82-87℃. I did try limiting it to 125W first, but the frame rate tanked and the cloud rendering became a choppy mess, so 180W is the sweet spot. CPU temps are now 78-84℃ and fans are steady at 1400-1600 RPM.
