How to fix thermal throttling on DeepCool AK620 in Kai no Kiseki?
When hitting high-density town areas, my AK620 core temps spiked to 88°C - 93°C, causing the clock speed to tank from 5.0 GHz down to 3.2 GHz. This kind of performance dive made me seriously doubt the actual headroom of this dual-tower cooler. At first, I tried slamming the fans to full speed in the BIOS, but the noise jumped past 40 dB while temps only dipped by 3 degrees—a total nightmare of noise vs. cooling. I eventually rebuilt the step curve: 50% speed at 65°C and a 100% peak at 80°C. Monitoring via HWiNFO showed cores stabilizing between 74°C - 79°C. Early on, I hit a snag where the fans wouldn't spin up due to low startup voltage, which I only fixed after switching the control mode from PWM to DC. Frame times finally tightened from 22ms to 16ms, and the tearing felt way less jarring with Sync on. It's a tedious process to balance efficiency, but it killed the thermal spikes. I saved the final curve parameters using a dedicated temp logger.
