I probably should’ve specified that I’m using a laptop, not a desktop. But my vent does get pretty darn hot sometimes so it might be that.
And yes, it takes a few minutes after I start rendering to turn off. At first it would stop everytime at a certain point so I thought something might be wrong with that clip. But then it went a bit further, and then stopped, so it can’t be that.
Also, I don’t know if this helps, but the problem started when I clicked on an old project and tried to save it. Before that, everything was fine.
