Undervolt Micro-Tuning and Airflow Optimization for Deepcool AK620
Stress logs showed that under max Ray Tracing, the CPU wasn't just hot—it was erratic. [HWinfo64 caught temperatures ping-ponging between 94℃ - 99℃], causing a frequency overshoot that manifested as screen tearing. I started by cranking the fans, but that was essentially spitting on a forest fire. I went into the BIOS, punched in a -0.075V offset, and re-engineered my case into a positive pressure airflow setup to purge the heat faster. [GPU-Z showed the clock locking into a stable 4.8GHz - 4.9GHz range], and [3DMark verified clock variance between 2ms - 5ms], killing the erratic jumps. The only lingering issue is that the absolute lowest 1% frames still dip beneath 35-40fps occasionally during the most intense scenes. I fell for the trap of following extreme OC guides which basically tortured my silicon, but this conservative underclocking is a total life-saver. Stability over raw numbers, always; I've finally stopped chasing the dragon of peak clocks.
