Why does Battlefield V stutter during explosions with Noctua NH-D14?

I felt totally robbed of immersion in Battlefield V; every time a massive explosion hit, my frames would tank. I tried enabling Windows High Performance mode, but it was a joke—the drops stayed and the fan noise became piercingly loud during low loads. I finally used the GamePP Fan Curve Configuration Panel to force fan speeds to 90% at 75℃ with a 2s hysteresis. Now, core temperatures stay at 72-78℃ per AIDA64, and frame times dropped from 15-42ms to 10-14ms via RTSS. It's finally smooth.
