Fixing CPU clock drops on Valkyrie V360 MERLIN in Gears 5
I was getting these annoying micro-stutters during intense firefights that made the controls feel sluggish and unresponsive. Looking at the logs, the Valkyrie V360 MERLIN pump in auto mode was just too slow, letting core temps bounce wildly between 70℃ and 90℃. I first tried switching the Windows power plan to High Performance, but while the clocks stayed up, the temp swings were still there—it was just a band-aid fix. I then went into the motherboard control panel, flipped the pump header from PWM to DC mode, and forced it to 100% full speed. AIDA64 stress tests showed temps converging to 65-72℃, and frame fluctuations dropped from 15 FPS to a mere 3 FPS. I did notice some annoying resonance noise right after locking full speed, but that vanished once I flipped the radiator fan orientation. Now the liquid temp sits at 32-36℃, hitting peak efficiency. System logs confirm no more throttling, with RAM temps holding steady at 58-63℃.
