How to reduce CPU use (temperature problems)?

My computer has been crashing several times due to high temperature while rendering. A temperature monitor showed me that CPU cores easily reach critical temps during renders. Is there a way to prevent this problem, I suppose by limiting CPU use by DAZ Studio (or by whatever other means?)

    With DS runing, find it in Task Manager's details tab, right-click on it, and select Set Affinity. You can then uncheck threads. It does sound as if your cooler needs cleaning or even reseating though.

    After looking at it :

    Set affinity allows me to prevent DAZ Studio from using one or more of the cores, right? But won't the others keep running at the same rate, keep overheating, and keep causing the system to crash?

    If you stop it using all cores that will reduce the heat produced - each core generates heat as it works.

    Makes sense. Thank you.

    Don't know what type of comp you have or build.  CPU heating is caused by varying factors, mainly dust, specially on fans.  If cpu is overheating, depending on cooling system, I would recommend remove/replace thermal paste for cpu, remove fan clean or replace.  Good luck.

    I installed a temperature tool to be warned when it rises too much (and interrupt the render until the computrer cools down a bit), and I'll try to clean the fans. Using one core less didn't seem to help much. On the other hand, it only happened on a day when it was particularly hot at my place. I guess it plays a part.

    Hopefully, I'll soon be able to buy a better computer for renderings, the one I use currently being an underpowered (2Gb Vram) laptop.

    Ah! A laptop. Those generally aren't designed with the idea they'll be running for many hours straight. And some, trying to lose as much weight as possible, sacrifice airflow and cooling to be able to brag about their weight savings.

    I had an old laptop for work that used to overhead badly for me even under normal use. I bought a USB powered laptop cooling pad from Amazon and it helped a lot to circulate more air through the case and keep things cooler.
