How to fix frame drops with the ML360 SUB-ZERO in MGS Delta?

The micro-stutters were absolutely killing the vibe during stealth segments. Looking at my logs, the ML360 SUB-ZERO's semiconductor plate was keeping the core at a chilly 35-42℃ on max power, but the condensation risk was driving my VRM temps over 75℃. I tried dropping the TEC power to 50%, but the core temp bounced back to 68℃ and the stuttering actually got worse, which was a frustrating reality check on power balancing. I eventually locked the TEC power at 75% and cranked the pump to 3000 RPM to flush the heat out faster. GPU-Z showed the core frequency stabilized at 5.4GHz without any thermal dips. I actually struggled with the radiator fans early on; they were too quiet, causing the water temp to climb to 45℃ in ten minutes. I fixed this by setting the fan trigger to 40℃. Now the whole rig is rock solid with even heat distribution. After a 3-hour stress test, memory temps stayed between 58-63℃, and the gameplay is buttery smooth.
