cpu-temp

An Intel CPU temperature monitoring library for Windows and Linux.

Features

• Read real-time CPU core temperatures
• Read CPU package temperature
• Support for Intel CPUs
• Multi-core temperature monitoring with physical core mapping
• Cross-platform support (Windows & Linux)

Platform Details

Windows

Uses MSR (Model Specific Register) access via the PawnIO driver for low-level temperature reading.

Linux

Uses the Linux hwmon subsystem (/sys/class/hwmon) for temperature readings. No special drivers required.

Requirements

Windows

• PawnIO driver must be installed for MSR access
• Run as administrator

Linux

• Root access or appropriate permissions to read /sys/class/hwmon files

Installation

Add this to your Cargo.toml:

[dependencies]

cpu-temp = "0.1"

Usage

use cpu_temp::cpu::intel::IntelCpuTemperature;

// Create temperature monitor
let mut temp_monitor = IntelCpuTemperature::new()?;

// Read temperatures
let data = temp_monitor.get_temperatures(&mut msr)?;
println!("TjMax: {}°C", data.tj_max);
for core in &data.core_temps {
    println!(
        "Core {} (logical {}): {:.1}°C",
        core.physical_id,
        core.logical_id,
        core.core_temp.temperature
    );
}
