What is acpitz virtual 0?

acpitz-virtual-0 is the temperature sensor near/on your CPU socket. This sensor can be unreliable. coretemp-isa-0000 measures the temperature of the specific cores.

How do you start a LM sensor?

Install the lm-sensors package (see InstallingSoftware). Run sudo sensors-detect and choose YES to all YES/no questions. At the end of sensors-detect, a list of modules that needs to be loaded will displayed. Type “yes” to have sensors-detect insert those modules into /etc/modules, or edit /etc/modules yourself.

What is k10temp PCI 00c3?

k10temp-pci-00c3 Adapter: PCI adapter. This sensor is provided by the k10temp kernel module which handles the AMD CPU, see http://lm-sensors.org/wiki/Devices. The related temperature is the CPU one. IIRC it8720, is a common chip on the MB, not possible to say more without manufacturer specification.

What is x86_pkg_temp?

Each of the different zones is a different thermometer on the system: the “acpitz” one is the one made available through ACPI, and the x86_pkg_temp is the temperature exported by the core x86 spec. The ACPI one is a motherboard sensor that is near the CPU socket, and the x86_pkg_temp is within the CPU itself.

What is Peci agent?

What is PECI? A. Intel has developed the PECI as a new interface that enables communication of the temperature reading of a systems’ host processor over a single-wire bus, enabling efficient platform thermal control. It is anticipated to replace remote diode interfaces now used in most systems.

What is TDIE and TCTL?

On some AMD CPUs, there is a difference between the die temperature (Tdie) and the reported temperature (Tctl). Tdie is the real measured temperature, and Tctl is used for fan control.

What is ACPI thermal zone?

ACPI Thermal zones are a logical collection of interfaces to temperature sensors, trip points, thermal property information, and thermal controls. Thermal zone interfaces apply either thermal zone wide or to specific devices, including processors, contained within the thermal zone.

What is PECI temperature?

Intel has developed the PECI as a new interface that enables communication of the temperature reading of a systems’ host processor over a single-wire bus, enabling efficient platform thermal control. It is anticipated to replace remote diode interfaces now used in most systems.

Which CPU temp should I pay attention to?

90C is a bit close to the thermal throttling temperatures. Anything below 80 or 75C is absolutely fine. Hardly any benefit whatsoever from pushing lower to some 50C. But 90C is right on the border of where most CPUs start losing performance.
