Why is my CPU throttling with a Valkyrie V360 MIST in Scarlet Nexus?

Whenever I spam large-scale abilities, the FPS slowly drifts from 120 down to 70, and it gets worse the longer I play. The default pump profile on the Valkyrie V360 MIST is way too conservative, leaving the core temps hovering around 88-92℃, which triggers thermal throttling. I tried capping the CPU state to 99% in Windows, and while the temps dropped by 10℃, I lost about 15% of my overall performance—too much of a trade-off for me. I ended up manually locking the pump PWM signal to a constant 85% and lowered the radiator fan threshold to 55℃. In stress tests, the max core temp stayed between 72-78℃, and the boost clock stayed above 4.6GHz. I noticed some slight tubing vibration when I first locked the speed, but a bit of cable management and securing the radiator fixed it. Now the coolant is steady at 38-42℃ with the pump at 2600 RPM. Cinebench R23 confirms zero performance loss, with clocks steady at 4.8GHz.
