I'm running bazzite on my desktop with an AMD 7800x3d and an AMD 7900XT gpu.

I have a PBO optimizer curve offset set to -30 in bios but I'm still getting pretty high temps in my case, even when idling. CPU is water cooled with a Corsair H110. CPU temps are around mid to upper 40c and can reach up to 80c when gaming.

I don't think it's an issue with the cooler because when when idling it's blowing out hot air on the exhaust fans in my case. The cpu cooling radiator is setup as an intake so it cools the liquid with cool ambient air.

I believe bazzite might be consuming a lot of power itself but I can't prove it because I have no way of viewing power usage. I tried setting up ryzenadj but it gave me an error about how my cpu family isn't supported. (It might be laptop only?)

If anyone has any recommendations I'd greatly appreciate it.

That's well within expectation

    Those temps are very normal. You can set cpu or frequency limits if you want to use less.

    1. Install powertop and run (with sudo) to see what's consuming power. Use the tunables tab for suggestions on what can turned on or off.

    2. You're on AMD, so your CPU scheduler should using the amd-pstate-epp module to handle power profile settings. Turn your power profile to power saving and see if your temps go down. Move up to balanced from there and see how that is.

    3. You sure you haven't over locked anything? Try setting defaults in your BIOS.

    4. Pic of your case and components couldn't hurt. You might just have an airflow issue

    How hot is the heat exchanger itself? If it's not warm at all, is there some plastic you forgot to take off the thermal interface?

    Edit: also, 80°C is normal operating temperature under load. If you're worked about heat damage, look up the max temperature in your CPU specs.
