My UE5 demo project keeps hitting massive frequency drops during real-time ray tracing, how do I stop this?

The stuttering during complex reflections was unbearable; it's the kind of hitching that makes a professional demo look amateur. The PCcooler RT500 TC ARGB just couldn't keep up with the massive power draw of my 14th gen chip, and I was hitting the motherboard's throttling threshold right around 92°C. My first instinct was to lower the CPU power limits in the software, but that was a mistake—temps dropped by 6°C, but my render times jumped by 20%. It was a frustrating loop of failure. I ended up ripping the cooler off and swapping to a high-end phase-change thermal paste, then remapped the PWM curve to start ramping at 60°C and hit full blast at 85°C. Looking at the RivaTuner frame time graph, those jagged latency spikes completely vanished, and frame times leveled out at 14-18ms. I actually messed up the first mount and didn't tighten the bracket enough, which left Core 2 running 7°C hotter than the rest, but a quick re-tighten fixed it. Now the CPU stays between 70-78°C. AIDA64 stress tests confirm no more clock drops, and my RAM is chilling at 58-63°C.
