Rasberry PI wifi issue, usb webcam and heat.

[Pradit]

It seem to be too many question in 1 thread but I suspicious they might be related.

My initial issue is the connection to rpi gone mid of the night.

I couldnt remote to monitor or telegram couldnt notify me.

It happen recently around the time I added extra cheap no brand usb webcam.

Now i had multicam octoprint plugin running pi cam and usb cam.

I only notice pi temp reach up to 60c while printing. Im not sure this happen normally coz I had never looked at it before.

May the cam heat up the pi and cause wifi gone?

Could I just use lan will solve this?

Or add fan to the pi or increase fan speed now its only 35% speed.

Yup, you definitely need a fan to provide active cooling. I notice my PIs start to act weird when thet get to high 40's let alone 60C. I also use a decent sized 24V fan for the cooling. I find those little 3010 5V fans that get sold for PI cooling are less than useless. With decent cooling my PIs never get above low 30s.

If you get the PI temperature under control with some active cooling (although heat-sinks helps as well) then you probably won't need to start worrying about removing cameras and wifi (I've had multiple USB cameras on a PI + WIFI without the need for anything drastic).

The mcu is heating and probably throttling the pi (slowing the processing down). What model pi is it ?

Definitely add a fan to the pi to keep it cool. Under load the mcu temp should ideally not be getting any higher than 38 degrees

I got 60mm 24v fan run at 100% mount to the pi without heatsink.

Now working temp under 48C.

Thing seem ok so far.

No heatsink on the Pi? That might be contributing. I have the typical aluminum heatsink set on my Pi, then just use the two electronics bay cooling fans. I swapped to Noctuas to quiet things down (12V instead of 24V). Those run all the time during a print & are on a delayed macro cycle during idle. My Pi stays about 40-50C and the Octopus stays mid-30's with that.
