Best CPU and GPU monitoring app

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

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.

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

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

Resources is a nice aio flatpak for system monitoring.

I use "GtkStressTesting" for tracking system's health, although it's actually a Benchmarking tool.

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.

I like ksysguard, comes with basic system monitoring screens and is very configurable.

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

I use the xfce CPU graph plugin for the CPU... don't use anything for GPU, I don't game and all my rigs run on onboard GPUs. There is also a temp plugin for xfce, I use that one as well, can't remember the name now though... it requires libsensors to work.

Resources is pretty good.
