Fixing VRM overheating on Soyo SY-Yanlong B550M?
The game would just black screen and reboot after 30 minutes without any warning. The anxiety of losing progress was real. Monitoring showed the VRMs on the Soyo SY-Yanlong B550M were hitting a scorching 105-110℃, triggering the motherboard's emergency thermal shutdown. I tried slapping an extra fan on the side of the case, but that only dropped temps by 3℃—still hovering around 98℃. Completely useless. I had to go into the BIOS and manually cap the CPU PL1 power limit from 105W down to 80W, and applied a -0.06V core offset. In OCCT, the VRM temps immediately plummeted to 75-81℃, and the crashes stopped dead. I noticed a drop of about 8 FPS after the power cap, but I managed to claw that back by enabling the memory's XMP profile. CPU temps now sit comfortably at 68-74℃ with fans spinning at 1100-1300 RPM. Four hours of testing and no more crashes; the input lag is gone and it feels responsive again.
