Location of sensors
Hello, I just wonder how to know the location of the sensors, I got a lot of them on my HP Probook laptop : hw.acpi.thermal.tz0.temperature: 87.0C hw.acpi.thermal.tz1.temperature: 47.0C hw.acpi.thermal.tz2.temperature: 72.0C hw.acpi.thermal.tz3.temperature: 59.0C hw.acpi.thermal.tz4.temperature: 26.4C hw.acpi.thermal.tz5.temperature: 55.0C acpi_tz0: Thermal Zone on acpi0 acpi_tz1: Thermal Zone on acpi0 acpi_tz2: Thermal Zone on acpi0 acpi_tz3: Thermal Zone on acpi0 acpi_tz4: Thermal Zone on acpi0 acpi_tz5: Thermal Zone on acpi0 For example I know that there is two sensors on the CPU unit, and one one on the Wireless chipset but which one?

It's also possible that contacting HP's support might dig up more info. Failing that, however, you might be able to look at the Hardware/Health Status page in the BIOS, note the relative temperatures being displayed and what they are with, and then compare the sysctl output after a boot. You might also be able to boot into Windows and try running a vendor-supplied thermal monitoring utility, and either look for debugging info, perhaps in the logs if it produces any, or again try to figure out the correspondence.

You could try running them while doing various things to try to affect different areas, eg running sysutils/cpuburn. I didn't try to define all the sensors because my problem was different and I solved it.
