CPU temps for Ryzen

[Ralph Little]

Would it be possible to add a pattern match for CPU temperatures with the sensors label Tdie?
I have done this for my Ryzen system but when I upgrade I have to make the change again.

I just added another entry in linux-lib.pl:

            elsif (/Tdie:\s+([\+\-][0-9\.]+)/) {
                    $rxx++;
                    push(@rv, { 'core' => 0,
                                'temp' => $1 });
                    }

It shows "Core 1:" but I am cool with that.

Hi,

What is the output of sensors command?

[Ralph Little]

k10temp-pci-00c3
Adapter: PCI adapter
Tdie: +54.4°C (high = +70.0°C)
Tctl: +54.4°C

I have linux kernel 5.4.0-53

Is this the temperature of the CPU itself?

[Ralph Little]

From what I gather from online resources, Tctl is the raw temperature detected at the heat spreader and Tdie is the proper computed value. On my machine they do seem to be the same. My understanding is that Tctl might have an offset which would need to be corrected.

I am running the machine at 100% so the temperature seems pretty reasonable.

Is this complete sensors command output?

[Ralph Little]

Yep, that's all I get for this machine after running the full probe. :(

Seems to work!
Thanks!
