My Sapphire Pure Polar RX 9070 XT hits a power wall during Valorant team fights, causing lag; how do I fix this?

This has been a total slog. The 'factory overclock' on this Polar edition is basically a lie because as soon as things get intense, the clocks dive from 2400MHz to 1800MHz. The Sapphire Pure Polar RX 9070 XT has a way too aggressive power management system that triggers a throttle the second it hits 230W. I tried the 'Overclock' preset in Adrenalin, but it actually made things worse by increasing heat and causing more drops—total joke of an optimization. I went into the manual tuning, dropped the voltage from 1.1V to 1.05V, and locked the max frequency at 2300MHz, while setting the fans to 80% at 70℃. In GPU-Z, the frequency curve went from looking like an EKG to a flat line. I did try pushing it down to 1.0V, but the game froze on the loading screen, so I had to bump it back up 0.05V to get it stable. Core temps are now 68-74℃. The fans are a bit loud, but the gameplay is finally consistent. I've backed up the profile just in case.
