Optimizing DeepCool AK620 fan curves for Phantom Blade Zero?
The default fan curve on this cooler is a complete joke; the second a fight gets intense, the CPU just hits 95℃. It's honestly ridiculous. The AK620 just doesn't ramp up fast enough for bursty workloads, letting the core temp jump from 60℃ to 90℃ in under 10 seconds, which triggers an immediate downclock. I tried swapping in some high-RPM third-party fans, but it just made the noise unbearable while only dropping temps by 3℃—a terrible compromise. I went into the BIOS and set up an aggressive stepped curve, forcing 100% fan speed the moment it hits 75℃, while also boosting the intake on my front case fans. In OCCT, the peak temp dropped from 96℃ to a manageable 82-86℃. I had some annoying vibration at low speeds during the first few tests, but raising the minimum floor to 800 RPM smoothed it out. Idle temps are 35-40℃. After ten hours of gaming, the FPS drops are gone and the controls feel tight again.
