My DeepCool AK620 ARGB is having thermal swings when building large bases in Palworld, causing micro-stutters. How do I fix this?

While placing a ton of structures, I noticed my core temps bouncing between 78-86℃. It wasn't shutting down, but the instability caused the clock speeds to jitter. I tried enabling Game Mode and flushing my RAM, but my FPS just hovered around 50-62 without any real improvement. I eventually went into the BIOS and switched the PWM control from Auto to Manual, setting a steep ramp-up curve starting at 80℃. In the monitoring panel, temps stabilized at 74-78℃, and frame times dropped from 14.2-20.8ms to 10.5-12.1ms. I actually tried bumping the core voltage to stabilize the clocks first, but that just caused local hotspots, and it took two reboots to roll back the settings. I realized thermal stability is the real key here. The fan noise is a bit rough at max speed, but the cooling is exactly where it needs to be. Cinebench confirms the cores stay at 74-78℃.
