A Redditor kicked off a GPU temperature check for MiniMax H3 generation. On his 4090 — 15-second clips, 0.8MP first pass plus 1.0MP upscale pass, monitored with MSI Afterburner and GPU-Z — he measured: core max 72°C / avg 68°C, hot spot max 83°C / avg 77°C, and VRAM max 78°C / avg 76°C. He's collecting comparisons from other cards, useful reference for local video-gen thermal headroom.
