CPU temperature not being properly reported.

[ghost]

The CPU temperature is directed to acpitz-acpi-0. Here it reports a the wrong temperature as my CPU runs 30-35C minimum (idle) in both Linux and Windows . After installing lm-sensors I ran sensors-detect, then the command 'watch -n 1 sensors'.

Here I saw the following.

I looked through extension.js and found that it was looking at thermal_zone0 when my CPU was being reported to thermal_zone1. Changing this and reinstalling the extension set the correct temp for my CPU.

From doing some googling I believe the first temp is the CPU Socket temperature.

I'm sure I'm the only person with this problem but I still though to report it just in case.

Take care!

You're not the only person. Should get an option witch sensor is reporting from. Reporting from acpitz-acpi-0 need k10temp-pci-00c3 $ sensors acpitz-acpi-0 Adapter: ACPI interface temp1: +16.8°C (crit = +20.8°C)

k10temp-pci-00c3 Adapter: PCI adapter Tctl: +42.5°C

Same problem for me, it gives me an error at the taskbar for temps, sensors output:

I've made a change at the file extensions.js, function _refreshCpuTemperature

        _refreshCpuTemperature() {
            const command_temperature = "sensors k10temp-pci-00c3 | grep Tdie | awk '{print $2}' | tr -d +";
            let proc = Gio.Subprocess.new(['bash', '-c', command_temperature], Gio.SubprocessFlags.STDOUT_PIPE | Gio.SubprocessFlags.STDERR_PIPE);
            proc.communicate_utf8_async(null, null, (proc, res) => {
                const [, stdout, stderr] = proc.communicate_utf8_finish(res);
                if(proc.get_successful()) {
                    let temperature = parseFloat(stdout.split('\n')[0].split('°')[0]);
                    if (this.cpuTemperatureFahrenheit) {
                        temperature = (temperature * 1.8) + 32;
                    }
                    if (this.displayDecimals) {
                        this.cpuTemperature.text = `[${temperature.toFixed(1)}`;
                    } else {
                        this.cpuTemperature.text = `[${temperature.toFixed(0)}`;
                    }
                }
            })
        }

Just run sensors and look for your processor sensor name, in my case is k10temp-pci-00c3, don't know if is the best way to do this but it works

Ok, now I've added the ability to choose what to monitor (from preferences). Please give me feedback especially for amd cpu (@fzamperin @machetie). Thanks for collaboration. P.S. this fix is in the develop branch.

[fzamperin]

Thanks @0ry0n, I was facing error problem, with this new develop fix I'm still having issues, this is my screenshot.

Strangely, the list of devices now in the thermal options for me are blank, no options available to select

[0ry0n]

Please give me this output. ls /sys/devices/virtual/thermal/ cat /sys/devices/virtual/thermal/thermal_zone*/temp

[fzamperin]

[0ry0n]

@fzamperin ok, are you in Virtual Machine?

[fzamperin]

No, I'm running a physical machine

Linux bife-desktop 5.13.19-2-MANJARO #1 SMP PREEMPT Sun Sep 19 21:31:53 UTC 2021 x86_64 GNU/Linux

[0ry0n]

@fzamperin ok, this should work.

[fzamperin]

Confirming, It's working now, the devices are detected, selecting the right sensor and temperature works.

And the temperature monitor:

Thanks a lot for your effort, really appreciate, this extension is amazing!!
