Valkyrie V360 can't keep up with CPU heat during late-game turn calculations in Civ 7. Boost pump speed?

Finally got my empire covering the globe without the game crawling. Originally, the Valkyrie V360 pump was idling at 2200 RPM, causing the CPU to hit 88-94℃ during heavy turn processing. Turn times jumped from 5s to 15s, which was absolutely infuriating. I tried undervolting to cut the heat, but the system just crashed during complex logic—a lesson that I needed more raw cooling. I switched the pump to 'Full Speed' mode (3200 RPM) and set the radiator fans to an aggressive 80-100% curve. HWInfo showed temps instantly dropping to 68-74℃, with clocks locked at 5.2GHz. I did notice some high-frequency vibration from the pump at max speed, but flipping the case fan airflow fixed the resonance. Liquid temps are now 32-36℃. BIOS confirms cores are stable at 68-74℃.
