Hi, I'm planning to leave the iMac 2.1ghz to render a batch from Cinema4d for 2-3 weeks. I tested it this weekend, leaving to render for around 60 hours and when I came back the temperature had gone up to 69º - everything works fine and the temperature dropped quickly to 64º when i stopped the render. Do you think it would be safe/sane to do the 2 week render or am I risking blowing the thing to pieces? Also would it be ok to nice Cinema 4d to maximum and have finder at the lowest possible cpu load? I could leave my Powerbook to assist in a NET render but I would really rather prefer to use it for other stuff... Anybody with experience on rendering in general on an iMac? Thanks.
