CPU overheats while Rendering Video

Fisk91 wrote on 4/19/2023, 6:03 PM

I have a Intel Core i7-13700KF CPU, and it only seems to overheat at times to 90-100 degrees Celsius when rendering videos on Vegas Pro. It also sometimes tends to get a little hot when skipping through the video on playback (in Vegas Pro) and hit play but this is more rare and doesn't seem to happen if I wait a little bit after skipping to a different part of the video and hit play.

It does not overheat when watching videos, playing video games, or multi-tasking.

I tried using settings on Vegas Pro where I can use the NVENC (graphics card) to help on the rendering process, but it still seems to overheat even while using this setting.

Is there any way to prevent my CPU from overheating while rendering via Vegas Pro, or any other method? Because I don't want to lower the life span of my PC for rendering videos.

Video rendering is very intensive and pushes your machine to its limits. The problem is that your machine's cooling isn't working adequately.

Are you using a desktop or laptop? Have you tried cleaning out any dust accumulation inside? Check that air intakes aren't blocked. What is your room temperature?

73 degrees Fahrenheit in room

I dusted my PC last maybe around 2-3 weeks ago? What do you mean by air intakes? The holes in the PC for air flow? If so it is not blocked.

You shouldn't be at such high temperatures if it's set up right.

In Intel Extreme Tuning run a 5 minute stress test and take a look at wattage and voltage and temperatures. After you ensure there aren't cables blocking the CPU cooler, consider adding fans if there aren't enough. Then set wattage limits in bios (200W) and try undervolting the CPU in the Intel app. Run the Intel CPU stress test for 5 min and see how temps are. Keep reducing voltage until you hit instability then increase again.

Then try editing and rendering in VEGAS and watch temperatures. With NVENC your CPU use likely isn't even 50% so if you're hitting 90C it's not a VEGAS issue, it's a cooling issue. See my signature for a 13th gen overclocked i5 on air cooling that usually doesn't get to 90C even if I'm doing an extended Mainconcept (CPU only) render.

If you have an ASUS Z790 motherboard, I have sample BIOSs at 70, 80 and 90 degrees C that I could share.

If your CPU is running that hot, it will have thermal limiting hitting in.

CPU, and overall, the entire computer having the proper airflow is important. The same with what CPU cooler you have installed. And you don't have to spend a lot of money to get excellent case and CPU cooling.

My 6 years old i5-6600 never gets past 78c when rendering (no mater what), with stock fans.

I have Coretemp on my taskbar.

Let's focus on the OP- the i9-13900K is a power hungry CPU with 24 cores and a 253 Watt TDP that can likely hit 350W if not limited, and generally requires water cooling. It can run up to 100C without thermal throttling.

The i5-6600 has 4 cores and a TDP of just 65 watts. It should be trivial to cool that CPU with just about any case and cooler.

@Fisk91 Suggest you set vp19 to defaults and make sure the Nvidia gpu and Intel igpu have the latest drivers. Get your graphics driver update from Intel and use the Vegas Help menu to get the latest Nvidia Studio Driver update.

Then confirm Nvidia is selected in Video Prefs and Intel is selected in i/o Prefs for decoding. That should enable you to render with Magix AVC templates to Nvenc (Nvidia) or QSV (Intel) with minimal cpu load. Assuming the format of your video clips is something Intel can decode with the igpu... it's best at avc 4:2:0 8-bit and hevc 8- or 10-bit. It can also do hevc 4:2:2 in the igpu without loading the cpu but it's not as fast as the others. If you're using some other kind of video clip format, like ProRes, that can only be decoded by the cpu but the load isn't that bad compared to something like 10-bit avc.
