Fixing CPU throttling in LoL with Noctua NH-D15 G2?

It's unbelievable that a top-tier air cooler was hitting the thermal wall during teamfights. The stuttering made my movement feel like I was lagging in a dream. I checked HWInfo and saw the CPU temp spike from 60℃ to 98℃ in literally half a second, triggering a massive clock speed drop. I tried enabling Power Saver mode, but my FPS tanked to 80, which was just a joke. I went straight into the BIOS and switched the PWM fan curve to 'Aggressive,' forcing the fans to hit 1500 RPM as soon as the CPU touched 70℃. Now, max temps are held at 78℃ - 84℃ and the clock is steady at 4.8 GHz. The first time I tried this, the fans sounded like a jet engine taking off, so I had to drop the idle speed below 50℃ to 600 RPM to stay sane. Fin temps are 35℃ - 40℃. I've exported the logs and the fans are now stable at 1400-1600 RPM, though the noise is still noticeable.
