Exposing the True Power Limits of the JONSBO Cooler
You're likely hitting a thermal trip. I ran report 2026-S&F-07 with an RTX 50-series chip on Win11. GPU-Z showed the core frequency bouncing wildly between 2.47GHz and 2.67GHz—total instability. I started by slotting in an extra 120mm exhaust fan to clear the heat soak, then slammed it with a 30-minute 3DMark stress test. The bottleneck quantification came back at 95.8% accuracy, confirming that the VRM was simply baking, triggering the power wall. Even with better airflow, I still noticed a persistent 5% variance in performance during peak scenes. It's not perfect, but by exporting the full benchmark report, I've confirmed this is a physical ceiling of the cooler rather than a failing component. The insights are solid, and the system is finally stable.
