Fixing voltage ripples on Cooler Master ML360 Sub-Zero?
The game would just hitch violently out of nowhere, and that kind of stutter is incredibly jarring when you're trying to soak in the horror atmosphere. The TEC module on the Cooler Master ML360 Sub-Zero pulls a massive amount of power, with peaks hitting over 220W, which caused my motherboard VRM voltage to bounce between 1.18 - 1.22V, tanking the CPU clock. My first instinct was to lower the shadow quality in-game; it gave me maybe 5 more FPS, but the hitching didn't stop because it was a power delivery issue, not a GPU one. I went into the dedicated control software and dialed the TEC intensity down from 'Extreme' to 'Balanced' and locked the pump at 2800 RPM. Checking RTSS, the frame time spikes of 16 - 32ms finally flattened out to 11 - 14ms. I actually saw CPU temps bounce back to 75℃ when I first lowered the power, but after re-applying the thermal paste for better coverage, it settled back to 55 - 62℃. Water temps stayed between 28 - 32℃. System logs confirm the voltage ripples are gone, and RAM temps are holding at 58 - 63℃.
