An RTX 5090 user reports extreme thermal stress when running the MiniMax H3 video generation model locally. Generating a 15-second video at 0.9x speed took about 15 minutes, during which the GPU fans ran at full speed and the temperature stayed consistently between 80–83°C.
The author noted that they never experienced such a heavy workload with wan2.2 or LTX 2.3. They advised users running this model on consumer-grade top-tier GPUs to pay close attention to case cooling, looking forward to better optimization solutions in the future.
