Is the DeepCool AK500 ARGB causing lag in Call of Duty 2026?

Watching my FPS jump wildly between 120 and 80 like an EKG monitor was stressing me out during multiplayer matches. The DeepCool AK500's default thermal profile has a massive 4-6 second delay in fan response during high-frequency power spikes, leaving my cores bouncing between 70°C and 92°C. I tried a 0.05V undervolt in the BIOS first, but that just led to hard freezes when loading large maps. I realized I couldn't just rely on undervolting. I went into the control panel and locked the fan speed above 90% while dropping the start threshold to 50°C. In RTSS, the frame time variance shrunk from a messy 15-40ms down to a tight 12-16ms, making the game feel way smoother. The fans did have a noticeable hum at idle, so I dropped the speed to 30% for anything under 40°C to get some peace. CPU temps now hover between 65-72°C with power draw at 130-150W. Stress tests confirm the stuttering is gone and the input lag is finally gone.
