Here attached is the screenshot when is visible the denoising where temperature reached 88 degrees.

How was the OC stability and temps tested? I always use Linx, even though it overloads the CPU more than rendering does. If it doesn't crash, and temps are acceptable, I'm sure it won't overheat during extended rendering sessions etc.

All overclocking, testing and monitoring are done within the same application Intel Extreme Tuning Utility.
Here is a screenshot with some detail about a rendering that is currently running. Is not finished yet so I don't have denoise temperature to show right now. I may upload the new chart later if may be of any interest.

Thanks to everybody bringing light to this and helping to keep safe my beloved CPU.

Hi SairesArt,

thanks for taking the time for this clear explanation. Now is clear what's going on. I think I will have to reduce a bit the OC or install some more efficient cooler on the CPU if I want to keep using the denoise function safely.

Hello,
my first post here as proud and happy user of Corona Render.
Now, I've some question for the experts.
I'm lately rendering high resolution still frames and, as you know, each minute spending rendering cost money, so I've opted for a moderate and safe overclocking of my workstation. I'm overall gaining about 30% in rendering time overclocking from 3.6GHz to 4.6GHz.
During the rendering time, of course, all 6 cores in my CPU are 100% used, and the temperature stay stable at a safe range of about 76 degree celsius. But, once the rendering is finished, and (ONLY) during the denoise process, the temperature raises to a warning level of 86 degree celsius (the cores of course stay at 100% usage).
So, clearly, the denoise function is way more CPU intensive than the rendering itself, or if this is not the case, the rendering process is not as efficient as the denoise function is.
Do you have an explanation for this behaviour?

Thanks
