How do I stop the Cooler Master B360 Core from overheating and throttling during Nioh combat?

Whenever I unleashed wide-area skills, my FPS would slowly bleed from 110 down to 60, a performance decay that got worse the longer I played. The B360 Core's stock pump profile is honestly too conservative, leaving my cores hovering around 88-92℃ and triggering a mild throttle that killed my clock speeds. My first instinct was to cap the maximum processor state at 99% in Windows; while temps dropped by 10℃, I lost about 15 FPS overall, proving that underclocking is just a band-aid. I ended up locking the pump PWM signal to a constant 90% and lowered the radiator fan trigger threshold to 50℃. Under stress tests, core temps stayed between 74-80℃ with clocks holding steady above 4.5GHz. I had some annoying tube vibration at first, but a bit of cable management and securing the radiator fixed it. Coolant temps are now sitting at 36-40℃ with the pump humming at 2700 RPM. Cinebench R23 confirmed zero performance loss, and my RAM stayed within 58-63℃.
