I recently got a premade desktop (specifically a Cyberpower PC) for my birthday 3 months ago, and while it functions for the basic uses that I need, I've noticed that its temperatures have been getting quite hot while rendering videos in Cyberlink Powerdirector 11.
While idling, my CPU temp reads in Piriform Speccy are between 22-26 degrees Celsius, with the temperatures reaching ~40 degrees while browsing and doing minor things online. When rendering videos of any size, length, or type, my CPU temp reads skyrocket to 80+ (although CPU usage doesn't go beyond 70%), which has led to it shutting down once due to overheating. It doesn't have any problems while running games like DotA 2 (temp reads are between 45-55), and otherwise it functions nicely.
I guess my basic question is this--is there any way for me to somehow limit my CPU temperature when it's rendering videos? After it had overheated the first time, it ran things very slowly for an entire day, but I noticed that it wouldn't let rendering temps go over 60 degrees (but the length of time that it took to render the files was tripled). For whatever reason after a fresh restart, it returned to normal where it would allow the temperatures to get quite high again. Needless to say, I've stopped rendering videos, at least until I can figure out a solution for this.
Regarding my PC specs, I've attached my DxDiag output, just in case this is helpful to anyone willing to help me troubleshoot and brainstorm this issue. Also worthy of noting, I have tried adjusting the affinity of the program via Task Manager, and regardless of how many processors I tick/untick, it doesn't change how hot the CPU gets when rendering--the only change that occurs is that it takes the files longer to be rendered.
One final comment--I have tried tinkering with settings in Cyberlink Powerdirector 11 regarding the hardware acceleration function. I've rendered videos both with hardware video encoding enabled and disabled, and the only difference is how long it takes the files to render. The temperatures still get quite hot with either setting.
Thank you so much for any insight you can provide. My ultimate hope is to just limit the temperature, even if it doubles or triples the time that it takes for the files to render.
