My CPU is throttling in God of War Ragnarok because the AK500 is overheating. What's the fix?

This was a total nightmare. Trying to run this game on a single-tower cooler is basically a torture test for your hardware; my FPS would tank from 80 down to 30 in periodic cycles. The DeepCool AK500 Ice Cube just couldn't handle the transient power spikes of a modern CPU, and the fins would heat-soak, pushing core temps to 95℃ and triggering severe throttling. I tried enabling the 'High Performance' power plan, but that just made the CPU hotter and the throttling happen even faster—which was just laughable. I ended up strapping a 120mm auxiliary fan to the back of the cooler and capped the CPU TDP at 125W in the BIOS to stop it from boosting too aggressively. Monitoring with HWMonitor, the temps dropped from 95℃ to 78-84℃, and the clocks finally stabilized around 4.2GHz. I actually bumped into my RAM sticks while installing the extra fan, which caused a boot failure, but once I reseated everything, it worked. Temps are now 72-78℃ with fans at 2200 RPM. Exported the BIOS settings to keep this stable config backed up.
