Is there a way I can make render times longer to avoid overheating? Whenever I render a picture above 16 samplings with Cycles, my laptop crashes in 5-20 seconds.
Is there a way I can manually make the render time longer while not affecting the quality of the render, so it doesn't get my laptop so hot it self-crashes to not melt itself? (I'm willing to use Add-Ons and, if there is a denoiser that could make a render with 16 samplings look like a render with 128 or 64 samplings that's okay for me as well.)
I live in a very poor country and can't afford a decent PC/laptop. Maximum I can afford is something below 50$ (Which would hurt my wallet quite a lot).
Here is a related SuperUser post.
In Blender, you can lower the number of threads by going to Render Properties -&gt; Performance.

Change from auto-detect and lower the number of threads.
I lowered mine to 2 and started a CPU render and it does appear to split the compute load pretty evenly among the processor cores, so one part of the chip won't necessarily be hotter than the other and it should prevent an overheat.

(This PC runs pretty hot.) :)
It's also worth quickly noting that denoising is a processor intensive task in itself, so it may not be a solution.
