Minimax H3 is quite resource intensive like no model before
is it just me or did anyone else notice several inference spikes that H3 seems to cause? It doesn't even happen during long lora training or running e.g. flux 2 dev, but this model brings the gpu temps to such a point where your rig might be ready to take off. no matter what workflow or even wan or ltx high res videos, it basically only happens with this model. i never encountered that before in comfyui. 5070ti and 32gb ram.
next to this, with the pruned int8 and the nvfp4 text encoder, the model still eats up at least 10-30gb of a page file quickly, depending on the video length (5-15sec).
