CPU Temperature not working

[TateFleming]

I have a Ryzen 9 7900X CPU. Lm-sensors does not report the CPU sensor stats, so this tool fails on it. Hopefully this will be supported in the future. In the meantime, I put in a work around (just look at nvme temperature instead of cpu) so the program still functions.

Another problem was the program looking for hwmon directories in the incorrect locations. I put in a quick-fix that works for my build, so I can now display full GPU stats.

If anyone runs into these issues and needs help, feel free to reach out. Better yet, if anyone has solutions to these problems, please let me know!

For the CPU temp, upgrade your kernel.

You had a problem displaying GPU stats?

[TateFleming]

Kernel is latest 5.15. No CPU stats reported from sensors, seems to be a known thing.

It was assuming GPU stats were at '/sys/class/drm/card0-HDMI-A-1/device/hwmon/' which returned an error. The stats are actually in '/sys/class/drm/card0-HDMI-A-1/device/device/hwmon/.' I don't know if this is something specific to my build or if it is new with Zen4. I'm new to all of this myself, so I could be doing something incorrectly.

That kernel is over a year old, I believe the monitor for those cpus was added about 5 months to the kernel.

Those are harmless errors, we iterate over the files to find the right one

[TateFleming]

Now kernel is 6.1.0. CPU temperature updates, but all GPU stats are messed up now.

[gort818]

What GPU, what exactly is messed up?

[TateFleming]

GPU is Radeon RX6600.

I'm trying to display CPU and GPU stats, temp, power. Also GPU core and mem clocks, and CPU mhz.

GPU showing 0%, cooler than expected temperature, constant 65535MHz for one of the clocks, and ~10W power. I have two amdgpu items that show up when 'sensors' is ran, it appears that MangoHud is grabbing the second when it should grabbing the first potentially?

CPU stats are good besides temperature is stuck at 655C.

VRAM displays 0.0GiB.

[gort818]

are you on the latest build of MangoHud?

[TateFleming]

Yes I am. I just removed it completely and cloned the repo again to verify.

[gort818]

7900X has an igpu doesn't it?

can you try this?
#802 (comment)

set pci_dev for your RX6600

I'm on a Ryzen 5 7600X and for me it's reading 655C temperature, doesn't sound quite right.
For the iGPU the reading seems to be correct though (but for that one the MHz one is slightly off, reading it as 65535MHz)

Tools like KDE's System Monitor seem to be able to read the temp correctly, so there's definitely kernel support.

Kernel: 6.1.4-x64v1-xanmod1-1
Mangohud: 0.6.8

I'm on Ryzen 9 7900x and it's also showing 655 degrees. Screenshot
The KDE System Monitor and sensors show the correct temps. Screenshot

Kernel Version: 6.0.18-300 (64-bit)
Mangohud Version: 0.6.8-1
OS: Fedora 37

Can someone with a zen4 show me the contents of the temp1_input file.

grep -rl "k10temp" /sys/class/hwmon/* 2>/dev/null | xargs -I{} sh -c 'cd "$(dirname "{}")"; cat temp1_input'

[valeth]

@gort818 returns 41000 for me

[gort818]

Thank you!
can you try this patch?
cpu.txt

[gort818]

Also if someone can give me the output of this
grep -rl "k10temp" /sys/class/hwmon/* 2>/dev/null | xargs -I{} sh -c 'cd "$(dirname "{}")"; cat temp1_label'
