Greetings fellow Solus user!
I'm currently running the latest Solus 4 GNOME edition, and while I do enjoy using it very much (I say this while not under duress!), I do notice quiet randomly and not often enough to pinpoint the problem, that my laptop will run rather hot. Right now it's about 65 degrees celsius, which is very warm to the touch! Not running any editing software or games mind you, this is just from a fresh boot, rather odd I find as GNOME doesn't always do this (and yes this can happen even when all extensions are disabled). At times though GNOME can run rather cool to the touch, but lately (last week or two) it's run a bit hotter than I prefer (looks towards Budgie).
Anyways! Get on with your question you may ask? Well for those curious I'm not so much looking for fixes and the like at the moment (i believe the culprit itself could be gnome-shell quite frankly 😛), but more I'm very curious what all the other laptop users out there are running and how cool or hot their systems typical are on average, so feel free to share! To get my CPU/GPU temp I use the GNOME extension Freon which works with the latest GNOME, or you can use a terminal of your choice and use the command sensors to see your temperatures.
I believe for my average temperatures right now, on the cool end it runs at about 49 degrees celsius and on the hot tamale end it runs up to 65 degrees. Looking forward to hearing from you all!
