How to stop thermal throttling on the DeepCool AK620 ARGB?
During massive team fights, my FPS would just dive from 200 to 140 out of nowhere, which totally ruins the timing for casting spells. The AK620's dual-tower setup has a bit of a lag in heat pipe conduction—about 12-18ms—causing the cores to spike to 86-91℃ under sudden load. I tried enabling 'Game Mode' in the drivers, which lowered CPU usage slightly, but the drops were still there; it felt like a surface-level fix that didn't touch the real problem. I went into the BIOS and set the fan curve to 75% at 65℃ and 100% at 85℃, and I added an intake fan at the bottom of the case to force more cold air in. Real-time monitoring showed the peak temp drop from 91℃ to a steady 72-77℃, and the FPS variance shrank from 40 frames to just 8. The fans were screaming at first, but I bumped the 100% threshold to 87℃ to find a balance. CPU power is now stable at 120-135W. Heat soak is gone and performance is verified.
