Solving Power Oscillation and Noise Issues in Unknown 9
Power drift is the worst for mental stability. I tried locking the clocks manually and just ended up with a black screen and a hard reboot. According to the [Pow-T600-Log] hardware data on a Win11 24H2 rig with driver v562.8, I used HWinfo v7.8 and saw the total system power oscillating violently between 450W and 580W, with spikes peaking at 620W during heavy Raytracing calculations. I dove into the BIOS hardware monitor and rewrote the fan profile for my Huntkey Blizzard T600 Snow from 'Auto' to a steep thermal staircase. I set 40-60C at 30% speed and only ramped up to 80% once it hit 70C, keeping the CPU steady between 61C and 67C, peering at 75C. After the fix, the power swing was still there, but the fan ramp-up became silky smooth, eliminating that drill-like screeching sound. However, for this silence, the VRM temperature actually rose by about 3C during peak loads. As long as it doesn't throttle, it is a fair trade.
