The list of running modules -

The EmbendURL modules only display on demand on a seperate page

My Pi5 has a on chip fan and it was running 75 inside the box attached to the monitor in the back.
I added external little fab on top of my enclosure to extract the hot air and it dropped the temp to 60.
Moved it 1 inch away from the monitor back panel and the temp now is 55 all the time with screen on and 44 during the night when the screen off.

You shouldn’t run any raspberry pi 5 without cooling fan on top it will break if run it without fan installed
Buy fan

I have ordered a fan/cooler

But anyone have any insight into whethere the processes I listed are over running?

@mvrlogins if you stop MagicMirror what is the temp?

It drops to 50C in a few min

what do you mean by separate page?
MagicMirror does not have pages, it has logical groupings of content, some shown together, others hidden (this is MMM-pages, MMM-Carousel, MMM-ModulesGroupsRotation, MMM-ProfileSwitcher, etc)
so even if not shown, some content could still be generated (Embed/iFrame) , they don’t know they are hidden

if you run ps -ef you can see the commandline used to launch each process.

you say you have a 1 gig pi5, but mem reports as 2gig.

but you are over physical, and swapping. which takes cycles.

I would suggest, disabling module at a time
add

disabled:true, 

after the module:name… line

and rerun to see what the effect is. what are the embed modules showing? active content, graphs, images??

The EmbedURL module shows a WebRTC video. The page is hiddent and called on demand (not regular rotation).

I thought that the module would not continue to stream the video when hidden. I guess this is the problem, since it does continue

[mvrlogins]

Instead of using pages to hide the module, I guess I could use MMM-Remote-Control to enable/disable the EmbedURL module? That would stop the streaming?

[sdetweil]

@mvrlogins i think runtime enable/disable just changes its visibility. there are no apis to add/remove modules from the DOM.
the disable at startup skips adding it as a runtime module… which is completely different

@sdetweil

Thanks

I’ll have to find another way to stop the streaming while the page is hidden
