How to fix the low-frequency humming and RPM spikes in Marvel Puzzle Quest: Dark Reign with Cooler Master MasterLiquid G360 RGB?

During a high-stakes team fight, the water pump emitted an annoying low-frequency hum that vibrated through the case to the desk, shattering my concentration. I tried switching to manual mode at a fixed 1500 RPM, but the temperature spiked to 85°C causing throttling, which was a frustrating dead end. I used GamePP Fan Curve Configuration to redraw the curve, capping RPM at 1200 below 70°C and ramping to 2000 above 75°C. AIDA64 stress test confirmed noise dropped to 36dB and temperature stabilized below 78°C.
