Proxmox cpu temp

1. Overview

In this tutorial, we’ll take a look at how we can check for the CPU temperature on the Linux terminal. First, we’ll see how we can figure out the temperature of our CPUs without the help of third-party tools.

Afterward, we’ll cover a couple of small useful utilities for the same purpose.

2. Finding CPU Temperature Without Third-Party Tools

On Linux, we can read almost every accessible detail related to hardware resources.

These details include the count of the CPU cycles, CPU temperature, I/O usage, network usage, and more.

This is all possible because Linux gives us more control over the hardware and software.

2.1. The /sys/class Directory

The /sys directory is a virtual file system that contains a plethora of information regarding the Linux kernel and the hardware. The files inside this directory don’t actually reside on the disk.

Instead, they’re only created and updated on-the-fly as we read them.

The /sys/class directory is the hierarchy of the hardware. This directory mostly contains information about the devices that
