My Librem 5 is quite warm—usually not too much to hold but nonetheless hot.
Is this a normal function of the device? My internal temp sensors appear to stay below 60° Celsius but do get quite close.

Mine gets hot. I find if I keep the modem off unless I need it to make a call, it sometimes gets less hot.
Also, for me Waydroid (especially with GAPPS) makes it very hot. [So I have never installed that on the eMMC and only install is on an SD card dual boot to isolate it.]
Something that might make mine run a bit better is that I would sometimes use tcpdump and/or wireshark to have the device listen to itself while idle, and then built-in components and services on the GNOME stack used to make Phosh (such as geoclue that send location home every 5 seconds or whatever) I would chop out and disable until it was moreso likely that the only networking the device would undertake would be the things that I want it to. And that might help it run better, but obviously if you need those systems and services then you might feel you’re missing something.
Can depend on user choice

It has occurred to me that perhaps this issue is related to my intense gaming addiction to SuperTuxKart.

Purism used the frame itself as a heatsink in the device, I believe. So whenever activity generates heat it’s going to be felt. The screen also transmits a good bit of heat.

I would say: Librem 5 is normal, but GTK is NOT normal.
GTK is very very obsessed with iPhone and iMac.

As long as it doesn’t go higher than 55°C, I would not mind, that’s normal (it already includes unexpected heat that is still okay). If it goes warmer, there is probably something wrong. Can you describe your situation where it becomes close to 60°C? Do you run something special (watching video on browser etc)? And is it warm where you live?

Booting from SD card will be the biggest heat producing factor, right after not having the modem’s USB link suspend (which is what happens on some distros that don’t read stuff from the modem’s QCDM port). Both of these keep the USB hub active, which is a huge power hog.

Yes, hence previous jokes on it. Like using it for a coffee coaster to keep your cup warm, defrosting your fridge, or keeping it in your car? Will the heat from a parked car damage your phone or will the heat from the phone damage your car.?

Maybe a solution could be to create a cover that helps to reduce temperature?
Eg: cold fluid like in cars or similar? Or micro fans? Of course, it’d be connected to L5 usb to take energy to works but it’d allow to use it preventing to be too hot…

@dos Do you mean any distro except PureOS? My Librem 5 is often at 57°C.

Mine is currently at 28.8°C while charging but it is idle and I have modem, bt and wifi off (running pmOS stable but upgraded to 5.5.92pure01 kernel). Ambient temperature is 22°C.

I am on Crimson. But no. Only after Videos or Fediverse Tuba sessions. Before on Youtube or social Media. Wlan was heating my phone more than mobile one.
