Why does the Valkyrie V360 Merlin cause clock speed drops during multi-sim loading in The Sims 5?

When building complex community scenes, my CPU temps shot up to 92-98℃, causing the clock speed to bounce violently between 3.2GHz and 5.1GHz. The default pump curve on the Valkyrie V360 MERLIN is just too sluggish when switching between low and high loads, creating a thermal lag that is honestly baffling. I first tried slamming the fans to full speed in the BIOS, but that just gave me a jet engine in my room while only dropping temps by 2℃—totally frustrating. I eventually dove into the control software and locked the pump at 3200 RPM, while bumping the radiator fan floor from 800 RPM to 1200 RPM. Monitoring via HWiNFO showed full-load temps plummeting from 96℃ to a stable 74-80℃, and the stuttering finally stopped. I did run into a weird issue where aggressive step-changes caused the fans to 'pulse' rhythmically; I had to increase the smoothing time to 3 seconds to kill that noise. Now, water temps sit at 38-42℃ and the VRM stays around 65-70℃. Stress tests confirm the cooling is now peaking, with water temps rock steady at 38-42℃.
