Why does my Valkyrie V360 MERLIN trigger thermal throttling during massive 10k unit battles in Warhammer 3?

Right when I was leading thousands of troops into a charge, my frame rate absolutely tanked from 75 FPS down to 28 FPS. It was a total nightmare; the stuttering made tactical deployment impossible. I realized the Valkyrie V360 pump was way too sluggish in default mode, letting the CPU core temps spike from 62℃ to a brutal 98-102℃ within ten seconds, which triggered a hard frequency lock. I first tried cranking up the case fans, but while the chassis felt cooler, the core heat just wouldn't move—a total waste of time. I eventually dove into the BIOS, flipped the pump header from Auto to Full Speed, and set the radiator fans to hit 100% once they hit 75℃. Checking HWInfo, the peaks finally settled between 82-86℃, and my clock speeds stayed consistent at 4.8-5.1 GHz. I actually dealt with some annoying resonance noise when I first maxed the pump, but getting the tubes sorted and adding dampening pads fixed it. Power draw leveled out at 210-230 Watts, and frame times finally smoothed out to 5.1-6.4ms. It's a bit loud, but at least it doesn't crash anymore.
