My Thermalright RT620P is failing to keep temps down in Dune Awakening, causing the whole system to hitch. How do I deal with this?

Core temps were swinging wildly between 92°C - 97°C, causing a noticeable frame drop every ten minutes. That kind of janky experience told me the contact surface was likely the culprit. I tried limiting CPU power via software first, but my FPS got sliced in half—a complete waste of time that didn't fix the root cause. I ended up stripping the cooler, reapplying high-conductivity paste, and tightening the screws in a strict diagonal pattern. I saw idle temps drop from 42°C to 35°C in CPU-Z. Even then, I noticed some slight fluctuations until I bumped the front chassis fans up to 1200 RPM to flush out the heat. Finally, the CPU frequency locked in at 4.6 GHz without those infuriating thermal spikes. This physical fix beat software tweaks hands down; the top of my case no longer feels like a hot plate. Even pressure on the base is the real secret to stability, and the stuttering is finally gone.
