Monitoring and adjustment of system temperature in Linux

Monitoring and adjustment of system temperature in Linux-Linux Enterprise Application-Linux server application information. For details, refer to the following section. Install tp-fancontrol to limit the gpu Temperature
UbuntuCPU temperature cat/proc/cpuinfo
The video card temperature has a sensor applet, which can be displayed when installed.
Run cpufreq-info on the terminal to view CPU Information

Sudo cpufreq-selector-c cpu No.
Or sudo cpufreq-set-c cpu number.
Select the CPU to adjust (because there may be more than one CPU on your computer)

Sudo cpufreq-selector-f the frequency you need
Or sudo cpufreq-set-f, the frequency you need
Adjust the cpu frequency. Note that the frequency here must be in the unit of KHz and can be reached (that is, the various frequencies viewed with cpufreq-info)

Yes.
Sudo cpufreq-selecotr-g Mode
Or
Suod cpufreq-set-g Mode

Here, the mode is the supported mode after you run cpufreq-info.
For example, powersave, userspace, ondemand, conservative, and performance.
Powersave is a so-called "power-saving" mode that maintains the lowest frequency in any case;
Userspace is the mode of custom frequency, which is automatically changed when you set a specific frequency;
Ondemand: a task with a cpu computing workload immediately runs at the maximum frequency, and returns to the minimum frequency immediately after the execution is completed;
Conservative is translated into a conservative mode, that is, the default mode. Generally, this mode is automatically adjusted at the upper and lower frequency;
Performance, as its name implies, focuses only on efficiency and keeps running at the maximum frequency.
