How to fix DeepCool AK620 cooling issues in Control 2?
In the middle of those debris-filled fights, my FPS was bouncing randomly between 50-70, which felt incredibly jarring. The DeepCool AK620's dual-tower design can cause airflow turbulence in certain cases, leading to a massive temp delta across the CPU cores—sometimes up to 15℃—which triggers localized throttling. I tried just bumping the fan speeds, but it only dropped the temp by 3℃ while making the PC sound like a vacuum, and the drops stayed. I ended up flipping the second fan to an exhaust configuration and applied a -0.05V offset in the BIOS. HWInfo showed the core spread shrink from 65-80℃ down to a uniform 62-68℃, and frame times tightened from 15-30ms to 8-14ms. I did notice the top of my case got hotter after flipping the fan, so I had to add an extra exhaust fan to clear the air. Now it stays at 64-70℃ and runs like a dream. Hardware parameters are finally verified.
