My Thermalright PA120 SE WHITE can't keep up with the heat in Crimson Desert, causing throttling. How do I fix this?

During massive war scenes, I noticed my CPU boost clocks becoming unstable as temps hovered between 88-94℃. While the PA120 SE WHITE's dual-tower design is solid, the heat buildup in my cramped case caused a roughly 15% drop in cooling efficiency. I first tried pinning the fans to 100%, but the noise was unbearable and the core clocks were still jumping around. I ended up redesigning my airflow, cranking the front intake to 1200 RPM, and setting a BIOS fan curve that hits 90% speed at 75℃. HWInfo confirmed full-load temps stabilized at 74-79℃, with clock fluctuations narrowing to within 0.1GHz. I actually had a bit of a struggle at first because I applied the thermal paste too thickly, which caused a 10℃ delta across the core—had to wipe it and redo it for a proper seal. VRM temps are now 62-68℃. Verified the cooling status with a heavy stress test.
