Running Stellar Blade at full tilt makes my Huntkey Blizzard cooler sound like a jet engine; can a quantified benchmark really reveal the performance bottleneck?

I pushed Stellar Blade to absolute limits with everything maxed out. In benchmark BN-SB-T600, a 30-minute 3DMark stress cycle revealed that the GPU core clocks started oscillating wildly around the 12-minute mark, bouncing between 2.45GHz and 2.68GHz while the fans peaked at a thunderous 2200 RPM. The analytic tools placed the bottleneck quantification accuracy in the 94.2% to 95.1% range, confirming a thermal wall. I previously spent hours tweaking case airflow, but the result was a pathetic 2 to 4 FPS gain—basically a placebo. Accuracy only came once I capped the power limit, which flattened the frame-time graph. That said, after an hour of heavy lifting, I'm still seeing rhythmic micro-stutters of about 3 to 5 FPS. The thermal mass of the Huntkey unit just isn't beefy enough to maintain steady-state equilibrium during these kinds of extreme extended peaks.
