My CPU is throttling and dropping frames in Rainbow Six Siege with a DeepCool AK620 ARGB; can I fix this?

The moment I tried to peak a corner, the game would freeze for 0.1s—it felt like I was playing on a 2G connection, which is absolutely ridiculous. The DeepCool AK620 couldn't handle the sudden power bursts, with temps jumping between 84-90℃ and forcing the CPU to downclock from 4.8GHz to 3.5GHz. I tried lowering the settings, but a 2℃ drop didn't stop the stutters; relying on software tweaks for a hardware heat issue is just a waste of life. I went into the BIOS, set the fan response time to 0.1s, and added a +0.02V core voltage offset to stabilize the boost. Using a temp monitor, I saw peaks drop from 90℃ to a steady 76-82℃, and the frequency crashes stopped entirely. The fans were way too loud during light tasks at first, so I dialed everything under 55℃ back to 900 RPM to find a balance. Now the CPU is smooth as silk. I exported the logs to verify, and the fans are now humming steadily between 1400-1600 RPM.
