Fixing cooling response lag on the Galax B760M D4 Wi-Fi
During massive Boss fights with screen-filling effects, every quick camera flick caused a micro-stutter that felt terrible. The fan response on the Galax B760M D4 Wi-Fi Black Knight had a 3-second lag between 75℃ and 85℃, letting the CPU core temp overshoot to 92℃ and trigger a hard throttle. I tried lowering the graphics to Medium, but while the average FPS went up, the temperature spikes stayed—clearly not a GPU issue. I dove into the motherboard control panel and slashed the fan response time from 3 seconds to 0.1 seconds, then capped the CPU power at 125W. HWInfo showed the peak temps drop from 92℃ to a manageable 80-84℃, and the drops mostly stopped. At first, the fans were ramping up and down constantly, which was annoying, until I set a 5℃ hysteresis interval to smooth it out. CPU now stays between 75-81℃ with fans at 1400-1600 RPM. Frame times are finally stable at 5.1-6.4ms.
