Solving overheating and throttling on Soyo SY-Classic B660M
This board should be more than enough for Tales of Arise, but I started getting random frame drops after about two hours of play, which makes me seriously question the VRM efficiency here. The VRM module on the SY-Classic B660M was clearly soaking up heat, pushing CPU temps into the 86-92℃ range and triggering aggressive thermal throttling. I tried enabling 'Power Saver' mode first, but the FPS plummeted to 42, which is a joke of a solution. I went into the BIOS and moved the fan trigger threshold from 60℃ down to 45℃ and pushed the max speed to 100%. In an AIDA64 stress test, the system finally ran for three hours without a single clock drop, with temps holding at 76-82℃. I actually tried adding a tiny auxiliary fan earlier, but it caused a weird chassis resonance that sounded like a bee in a bottle, so I had to rip it out. CPU temps are now 74-80℃ with fans at 1600 RPM. The stuttering is gone, and I've backed up the BIOS profile.
