How to fix overheating on Manli Snow Fox RTX 5070 OC?
During fast building sequences, I'd get these tiny, micro-stutters that were barely noticeable but totally ruined the game feel. Monitoring showed the GDDR7 memory on the Manli Snow Fox 5070 was hitting a wall at 85℃, triggering hardware thermal throttling that crashed the core clock from 2400 MHz down to 1900 MHz. I tried lowering texture quality, which gained me a measly 5 FPS but didn't stop the overheating—a pretty useless attempt. I finally went into the control panel and set a custom fan curve to hit 80% speed as soon as it touches 65℃, and dropped the power limit to 95% to keep the heat in check. RivaTuner showed the frame time variance shrink from 15-30ms down to a tight 12-16ms. At first, the fans were too loud during idle, but I fixed that by setting a zero-RPM mode for anything under 40℃. Core temps now hover between 72-78℃. 3DMark stress tests confirm zero drops; the card is finally behaving.
