Hware Acceleration def? Dangerous temps turned off

Help/How To
1

Should hardware acceleration be default if available? I rendered a video with an Intel I5-11600k (using iGPU on PC) without hardware acceleration and the CPU temperatures elevated to 92°C, where I promptly canceled the render. It could have gone higher, I didnt want to risk it.

I turn on H.A. and it renders a little faster while the temps don’t raise above 70°C.

I have read where you can lower priority in task manager. Also, in Power Options you can limit CPU power percentages. Haven’t tested too much but just lowering to %90 seemed to shave +10°C. But of course H.A… weird.

Wonderful program, thank you!

I do not think so. On many systems hardware encoding is unreliable or lower quality.

I do not see this as a problem. Modern CPUs have thermal protections built in and will reduce their clock speeds automatically to avoid thermal damage.

Rendering for long periods of time and life of the CPU was my concern. Thank you for the info.

Ahh… didn’t come across that, thank you.

I was thinking of adding a second fan anyway to the CPU cooler for the coming summer and/or taxing programs. …and I’ll also look into motherboard fan rpm graph.
