How to fix VRAM overheating on Manli Snow Fox RTX 5080 OC?
Swinging through downtown Manhattan was great until my 120 FPS suddenly tanked to 45 FPS out of nowhere. That kind of hitching is absolutely lethal when you're moving at high speeds. I checked GPU-Z and saw the GDDR7 VRAM on my Manli Snow Fox RTX 5080 OC was peaking at 98-102℃, which triggered a hard thermal throttle. My first instinct was to lock the core clock at 2600 MHz, but that was a disaster—VRAM temps soared even higher and the whole system just black-screened and rebooted. I realized I had to prioritize cooling over clocks. I went into the fan control and moved the trigger threshold from 60℃ down to 50℃, cranking the max speed to 85%. In GPU-Z, the VRAM temps finally settled between 82-86℃, and the frame variance shrank from 30 FPS to just 5 FPS. The fans sounded like a jet engine at first, which was pretty grating, but switching to a smooth stepped curve made it tolerable. Core temps stayed at 65-71℃ with power peaks around 320-340 Watts. After a two-hour stress test, the VRAM stayed locked at 82-86℃.
