I set my new AI Prime 16 down on the couch while I waited for the app to go through its several minutes long start up procedure. I came back to a smoking couch because the program auto starts at 100%. I feel like this should not be the default setting.
I did the same thing with a used hydra 32. I was testing it and put it on piece of cardboard light side down and it came on full blast so I went to unplug it. It was on the cardboard for maybe 5-10 seconds and it was burn through entirely and smoking. It's amazing how hot they get.
