I'm trying to do animation sequences of rather detailed models, using both raytraced shadows in the scene and clear and reflective elements. This results in render times that can excede several minutes per frame. Even after thoroughly auditing the scene for any and all simplifications I can make, and unnecesary materials that I can dissable the ray tracing on, I still get these long render times.
I'm not complaining about the times, I know it's the price to pay for using those features to get the great imagery effects, but I am worried about what doing these sequences will do to my machine when I start trying to render them out. I keep the ports and cooling fans clean, but other than that, and auditing scenery for simplicity and unnesesary RT active materials, I'm short of ideas here.
During any render job, my machine just dives in and shrieks full bore running at an absolute 100% capacity for each entire frame, with just a brief set-up occuring between each frame, where the workload appearently relaxes and appears to stem the heating process when the frame times are short enough.
I can usually achieve, and am happy with, render times of between 4 and 10 seconds per frame, as there is enough pause and reset time between them to keep my machine from overheating. But these longer times really worry me, as my core temperatures shoot up to become outrageously hot on just one frame.
Is there a way I can "throttle down" the "effort" (sorry I don't know the terms for this stuff) that my machine puts into doing these render jobs, like a setting in Blender that will tell the machine to run at only 50%, or say 30% capacity while doing these jobs? I could be comfortable just setting it up to run for hours at a time that way, or overnight with a restriction like this.
