Fixing VRAM overheating on Manli Star Ship RTX 5090 D v2?
Hitting 300km/h and suddenly my screen is covered in these glitchy green pixels—it was honestly stressing me out. The GDDR7 memory on the Manli Star Ship RTX 5090 D v2 OC was hitting 98-105℃ under full load, which is basically the thermal ceiling. I tried lowering shadow quality in-game, but it only dropped the temp by 3℃ and made the game look washed out, which I hated. I went into the control panel and set a super aggressive fan curve, forcing 80% speed as soon as it hits 60℃, and capped the power limit at 420W. HWInfo showed the VRAM temp dropping to 82-88℃, and the flickering vanished. I did have a moment where the case started vibrating like crazy due to the fan turbulence, but slowing down the front intake by 200 RPM quieted it down. The core stays at 64-70℃ with VRAM usage at 85-92%. After 10 benchmark runs, the pixels are clean and the input response feels snappy.
