  • $\begingroup$ Blender will use your computer hardware to render, I don't believe the resolution has anything to do with heating your hardware, except that it will take longer, so your processor will be working for longer. This question is about hardware not about Blender. $\endgroup$ – Georges Jun 14 '16 at 18:51
  • $\begingroup$ Ok. Thanks for the information. I'll delete this question $\endgroup$ – Jml19 Jun 14 '16 at 19:44

For complex rendering in general, reducing the "threads" can help. (Under performance tab in render) The computer will auto-calculate it, but you can set it lower than the auto value through the "fixed" option. The render will be slower, but it will be less intense and cause less heating/crashes.
