Laptop running hot/loud when OBS is open?

[jsolomonster]

Any input is appreciated. As soon as I open OBS, my laptop fans always get hyper, and even keeping the program open for a couple of hours without actually streaming or recording, my laptop temperature will rise from, say, 36C to around mid-forties. I don't do much gaming with the laptop, but live stream multiple times a week to YouTube talking sports, etc. so it's really just me on camera, that's it. I have not experienced any performance issues, lagging, crashing, encoding overload messages or anything like that, I just wish I knew why OBS causes such a spike in temperature and fan noise as compared to any other program I use and see if there is a reason for it/way to reduce it.

I did get the back cover off my laptop few months ago to dust the fans, I bought a stand to elevate the laptop off my desk to allow the fans more room to breathe, etc., but wouldn't say any of these things have helped specifically when OBS is open. Perhaps certain settings could be tweaked, but this is why I wanted to ask. Any help is appreciated.

And yes, I know I am running an older version of OBS, but have been resistant to update as I don't want to screw anything up.

That would likely be due to all your plugins actively doing what they do plus OBS rendering the preview
Check your Task Manager to see what is running

See threads on how the real-time compositing computationally demand work starts with opening OBS Studio into a Scene Collection with a video source (typically). Recording/Streaming is simply outputting the rendered video already created.

Thermally constrained laptops are not great platforms for real-time video work (see 4K video editing requirements to get a sense of what is involved)... doable, with care, but easy to overload a system if you aren't careful

Then running at 60fps... screen refresh rate not an even multiple of the FPS (ie, 120hz refresh rate, not 165, with 60 fps)
then streamelements PoS puking all over the log (and presumably issues don't stop with just the OBS Studio log)... some of which may be user settings/config

then lots of issues in that log with devices not found, etc... none of which can be helping matters

so, yea, what deFrisselle said...
- I'd recommend learning how to do some real-time hardware resource utilization monitoring, and add on top of that, the methodology specific to your make/model laptop in terms of thermal monitoring
- and so OS clean up on audio devices (I'm guessing) and/or Audio device config within OBS Studio.
