During rift jumps in Ratchet & Clank, my Noctua NH-D15S has a response delay causing instant temp spikes and lag. Should I change the fan strategy?

Whenever the game jumps between dimensions, the CPU load spikes instantly, causing core temps to leap 15°C in a single second. It's a very noticeable jolt. The Noctua NH-D15S fans are usually too polite, which let heat build up at the base and triggered an instant throttle. I tried enabling 'Ultimate Performance' mode in Windows, but the fan noise became piercingly shrill—a trade-off that made me want to try a more professional tune. I went into the BIOS and steepened the fan curve slope, forcing 100% speed once it hits 70°C. The monitoring panel showed peak temps dropping from 85°C to a manageable 72-76°C, and the lag vanished. I did experience some annoying fan start-stop oscillations at low loads until I locked the minimum speed at 600 RPM. Now the CPU stays between 58-65°C and the delivery is perfectly linear. I switched the profile from Silent to Performance via the management software.
