Is conky still a thing? I used it for that when I used an exclusively passive cooled PC a few years ago. You were able to easily create bar graphs in a config file and even include output of commands.

Mission Center, UI kinda like Windows 11: https://flathub.org/apps/io.missioncenter.MissionCenter

I currently use a combo of btop and radeontop for this. For GPU monitoring I’ve also used nvtop.

I use “GtkStressTesting” for tracking system’s health, although it’s actually a Benchmarking tool.

Resources is a nice aio flatpak for system monitoring.

On KDE there’s System Monitor, which you can customize to show graphs for CPU usage and temp, among other things, and GPU usage and temp too.

For in-game monitoring there’s Mangohud, also very customizable on what you can show in the overlay

Isn’t there Green With Envy to monitor NVIDIA stuff on Linux?

If you’re using an amd gpu, corectrl gives you a ton of info and controls.

bpytop is very nice and functional. Maximize the window and it almost hypnotic to watch.

Mission Control looks pretty nice, it tries to resemble the Windows Task Manager really closely so it’s great if you are switching from Windows

Resources is pretty good.
