Thermal stress testing Soyo SY-Yanlong B550M in Warhammer 3
This game is absolutely brutal on the CPU; it practically baked my B550M alive. During massive army clashes, the VRM temps spiked to 102°C, triggering a massive clock throttle that tanked my FPS from 70 down to 25. It was like watching a slideshow, and I almost threw my mouse. I tried limiting power in software, but the 1% lows stayed at 20 FPS, which was unacceptable. I went the aggressive route: I strapped a small active fan directly onto the VRM heatsinks and slashed the fan response delay from 3s to 0.5s to keep up with the heat spikes. HWiNFO showed the peaks were finally suppressed to 84°C - 88°C, and my clocks stabilized at 4.4GHz. The fan mod created this weird high-frequency resonance in the case, but I'll take a bit of noise over a fragmented screen any day. CPU idles at 36°C and hits 86°C under load. I exported the logs, and frame times are now a steady 5.1ms - 6.4ms.
