ubuntu 查看 CPU 温度

Catálogo

很多博主都推荐

$ sensors

但是不同的主板获取的都不太一样，比如在 A320H 上是这样的

勉强能看出来 CPU 温度是 +37.5°C

在我另外一台机器是

$ sensors
gigabyte_wmi-virtual-0
Adapter: Virtual device
temp1:        +34.0°C
temp2:        +38.0°C
temp3:        +78.0°C

temp5:        +55.0°C
temp6:        +52.0°C

acpitz-acpi-0
Adapter: ACPI interface
temp1:        +16.8°C
temp2:        +16.8°C

k10temp-pci-00c3

Tctl:         +78.4°C
Tccd1:        +67.5°C
Tccd2:        +68.0°C

nvme-pci-0100

Composite:    +40.9°C  (low  = -273.1°C, high = +89.8°C)
                       (crit = +94.8°C)
Sensor 1:     +40.9°C  (low  = -273.1°C, high = +65261.8°C)
Sensor 2:     +43.9°C  (low  = -273.1°C, high = +65261.8°C)

那压根看不出来了

推荐使用 inxi

$ inxi -CMs
